The best neodymium magnets, compared.
Top pick: NXPUXP 80 pack, 10 mm x 3 mm Best value: Wukong 100 pack, 5 mm x 2 mm – About £5.94 for 100 discs, score 80, N48 on the bullet and 4.5 from 4,341 reviews. The 26 g line is paper. Updated 23 October 2026.
A neodymium magnet is a sintered NdFeB piece: a disc, a block, an adhesive bar, or a steel-cup pot. In the UK you buy a multi-pack for notes on a steel fridge, a whiteboard, light craft, or a screw-fixed catch. You tell a suitable listing by the millimetres, which have to match the title. Prefer a stated grade, such as N42 or N52, and a pull off mild steel. A paper weight is a different claim. At the same size a higher grade is stronger, and a larger magnet still beats a tiny high grade. Nickel-copper-nickel plating slows rust. It does not make the magnet a toy, a waterproof fitting, or safe beside a pacemaker or a bank card. Loose discs around 5 mm are an ingestion hazard. Product safety alert PSA1 and NHS pages treat a swallowed magnet as an emergency even when the child looks well. If you cannot keep those discs away from children, do not buy that pack. Size, grade and fixing are set out in the [neodymium magnet buying guide](/hub/diy-supplies/neodymium-magnet/sub/neodymium-magnet-buying-guide).

Question 1 of 2
What are you holding?
NXPUXP is eighty 10 mm by 3 mm discs in a plastic case at £9.99, with 4.6 from 432 reviews. Grade and pull are not stated. The number-of-packs field says 6, which does not match a single case of 80. The listing says they are not toys and should stay out of mouths. A 10 mm disc is a step up from a 5 mm or 6 mm note magnet, and one review use is holding a fridge door, which is a catch rather than a photo. The case helps storage. Choose them when you want a larger everyday disc and a box. Do not treat the missing grade as N52, and do not use them as a specified door catch.
Pros
Cons
Best for: A larger everyday disc for a steel fridge or whiteboard, with a case for storage.
Less suitable: A specified door catch, a printed grade, or a paper claim you can quote in grams.
Specifications
Common questions
What size is each disc?
The title says 10 mm x 3 mm. The size field also says 0.394 in x 0.12 in, which is the same size in inches.
Are they marked as a toy?
No. The bullet says they are not toys, not to put them in a mouth or nose, and that children need supervision.
Is a case included?
Yes. The bullet says 80 discs of 10 mm x 3 mm come with a plastic case.
FIRST4MAGNETS F646-N52-1 is one 20 mm by 10 mm N52 disc at £9.99, with 4.6 from 95 reviews, the only single in this set that prints both a grade and a mild-steel pull. This amazon.co.uk listing says up to 14.8 kg vertically from the face, flush on mild steel. The maker's page for the same code prints 14.6 kg and 2.92 kg slide. Neither figure was retested here. There is no screw hole and no adhesive. Reviews mention finding screws in walls, and chips if the disc is dropped, and a thick disc can mark paint. It is the one to buy when the kilogram has to be written down and you will not put it on a fridge door. It is a small sample next to the multi-packs, and it is the wrong magnet for paper.
Pros
Cons
Best for: A single heavy pull where the grade and the mild-steel sentence have to be on the listing.
Less suitable: Photos on a fridge, a screw fixing, or any load you read as sideways slide.
Specifications
Common questions
What pull is printed?
This amazon.co.uk listing says up to 14.8 kg vertically from the face, flush on mild steel. The maker’s page for code F646-N52 currently prints 14.6 kg. Neither figure was retested here.
Does it have a screw hole?
No. It is one plain disc. The listing does not include adhesive or screws.
How many reviews are on the listing?
4.6 from 95. That is a smaller sample than the multi-packs. Reviews mention finding screws in walls, and chips if it is dropped.
Wukong is one hundred discs at £5.94, titled 5 mm by 2 mm, with N48 on the bullet and 4.5 from 4,341 reviews. The bullet also says about six sheets of A4, about 26 g, which is a paper claim, not a pull off steel. The dimension and thickness fields say 5 mm, so the title and the spec line disagree on thickness. A box is included. At about 6p a disc this is the best value in the set when you want a stated grade and a large pack for notes, and you should measure a disc when it arrives rather than trust the 5 mm field. Do not read 26 g as the same kind of number as an 8 kg or 14.8 kg steel claim.
Pros
Cons
Best for: A large pack of tiny discs for notes on steel, when you want a stated grade and a box.
Less suitable: A stated steel pull, a pocket that must be exactly 2 mm, or a house where loose 5 mm discs cannot be stored.
Specifications
Common questions
What does the 26 g pull mean?
The bullet says about six sheets of A4, about 26 g, and the pull field copies 26 grams. That is a paper claim, not a pull off steel.
What size are they?
The title says 5 mm x 2 mm, with a stated tolerance of ±0.2 mm. The dimension and thickness fields say 5 mm. Those two lines disagree.
Is there a storage box?
Yes. The bullet says the 100 discs come with a box.
The walolo pack is forty nickel-plated discs listed at 6 mm by 3 mm, £3.99 on amazon.co.uk, with 4.4 from 6,085 reviews, the largest review file in this set that belongs to one listing. Reviewers use them on a fridge or a whiteboard, and the listing says they are not a toy. No grade and no kilogram pull are printed, so a comment that calls them N45 is a review line, not a specification. The model field says LG Beauty LED Mask, which does not describe a magnet pack. At about 10p a disc, as a rule of thumb, this is the top pick here when you want a small everyday magnet and you can keep loose discs away from children. They are the wrong tool if you need a stated pull on mild steel or a screw fixing.
Pros
Cons
Best for: Notes or light photos on a steel fridge or whiteboard, if you can store loose discs away from children.
Less suitable: A screwed catch, a printed grade, or a kilogram measured on mild steel.
Specifications
Common questions
How many magnets are in the pack?
The title, the piece count, and the unit count all say 40. Each disc is listed as 6 mm in diameter and 3 mm thick.
Do they include adhesive?
No. The listing describes loose nickel-plated discs. You would need your own glue if the other surface is not steel.
Are they sold as a toy?
No. The listing says they are not a toy and can cause serious damage. No grade is printed. One review calls them N45, which is not on the spec line.
WATELL is a 6 mm by 3 mm nickel-copper-nickel disc pack at £4.99, with 4.4 from 1,031 reviews. The title and the piece count say 40, and the unit count says 50, so you should not assume fifty discs will arrive. No grade and no pull figure are printed. The bullet claims they come off a board or fridge without marks, which is a claim, and reviews describe them as small and strong enough for a few photos. Glue is not included. They suit a fridge or office board if a 6 mm disc is big enough and you accept the count clash. They are a poor choice when the listing must state a grade or a steel pull.
Pros
Cons
Best for: A fridge or office board when a 6 mm disc is enough and you can live with the 40-versus-50 count.
Less suitable: A job that needs a stated grade, a steel pull, or a reliable count of 50.
Specifications
Common questions
How many are in the pack?
The title and the piece count say 40. The unit count says 50. Those lines disagree.
Will they mark the fridge?
The bullet says they come off a board or fridge without marks. That is a claim. Reviews describe them as small and strong for a few photos.
Is glue included?
No. A review says to buy glue if you are making fridge magnets for non-metal objects.
VACUBXBY is six 20 mm by 6 mm countersunk pot magnets with six M4 screws at £4.99, and 4.4 from 216 reviews. The spec field says 25 pounds, the bullet says over 25 lb, and also 20 lb on the metal plate in the pack. A review says 25 lb feels overstated. Grade is not stated. The bullet describes a neodymium magnet in a steel sleeve, which is the pot shape: one working face, a screw through the countersink. Reviews mention a shed door and a drawer. They are the pack in this set when you can screw a catch flat to steel and you will not overtighten the screw. They are the wrong buy for paper on a fridge, and the 25 lb line is not the 13.2 kg figure printed on a different, thicker N42 pot.
Pros
Cons
Best for: A screwed catch flat against steel, such as a drawer or a shed door, if you tighten the M4 by hand.
Less suitable: Paper on a fridge, a pull through paint or a gap, or anyone reading 25 lb as a 13.2 kg specified pot.
Specifications
Common questions
Are screws included?
Yes. The bullet says six 20 mm x 6 mm pots and six M4 screws. The hole is countersunk, so the screw head is meant to sit in the face.
Which pull figure is printed?
The spec field says 25 pounds. The bullet says over 25 lb, and also 20 lb on the metal plate in the pack. A review says 25 lb feels overstated.
Can they screw to wood?
The listing says they can be screwed down or stuck straight to steel. There is no adhesive pad in the pack.
The Yizhet 50-pack is titled 10 mm by 2 mm at £7.99, nickel coated, and the page shows 4.3 from 23,178 reviews. That count and the review text are the same row as the other Yizhet ASIN, including comments about a 20 mm disc, so it is not a sample of this thickness alone. No grade and no kilogram are on the spec fields. The dimension field only says 2H millimetres, and the model and part numbers do not match. The bullet says they are not a toy. You might still use a 10 mm by 2 mm disc for a whiteboard if the pieces that arrive match the title. Do not treat 23,178 as proof this size is the most reviewed magnet in the set.
Pros
Cons
Best for: A whiteboard disc only if you measure what arrives and you ignore the shared review count.
Less suitable: Choosing on the star count, or any job that needs a grade and a steel pull.
Specifications
Common questions
Are the 23,178 reviews all for this size?
The listing shows 4.3 from 23,178, and the review text matches the other Yizhet ASIN, including comments about a 20 mm disc. Do not read that count as this size alone.
What size does the title state?
10 mm diameter and 2 mm thick, 50 pieces. The dimension field only says 2H millimetres.
Are they a toy?
The bullet says they are not a toy. No grade and no kilogram pull are on the spec fields.
This Yizhet listing is twenty pieces at £7.99, with the title saying 10 by 10 by 4 mm and a bullet saying 10 by 4 mm. The shape field says rectangular. It shows the same 4.3 from 23,178 as the 10 mm by 2 mm Yizhet discs, and the review text matches, including other sizes. The coating line says nickel, written NiCuNi, on NdFeB, and the listing says they are not a toy. No grade and no pull are printed. Buy it only if you want a small block and you will measure the piece, because the two size lines do not agree. Skip it if you are choosing on the star count.
Pros
Cons
Best for: A small block only if you measure the piece that arrives and you do not need a stated pull.
Less suitable: Anyone choosing from the review count, or a recess cut to one of the two conflicting sizes.
Specifications
Common questions
What size is printed?
The title says 10 x 10 x 4 mm and 20 pieces. A bullet and the size field say 10 x 4 mm. The shape field says rectangular. Those lines do not agree.
Is the review count for this block?
The page shows 4.3 from 23,178, the same row and the same review text as the 10 mm x 2 mm Yizhet discs, including other sizes.
What is the coating?
The bullet says nickel, written NiCuNi, on NdFeB. The listing says they are not a toy.
Grtard sells four 30 mm by 3 mm discs at £8.59, with an 8 kg pull claim, adhesive pads, and 4.3 from 2,959 reviews. The listing does not name the test surface and does not print a grade, and it warns that the pack is for ages 15 and over. Reviews describe the discs as very hard to separate, with buyers needing real effort to prise a pair apart. The pads held on some metal and failed on picture frames and in a hot car, so the magnet and the glue are not the same strength. Use them when you want a wide disc and you will check the bond yourself. Skip them for a child's fridge or for a frame that must not fall.
Pros
Cons
Best for: A wide disc for a workshop catch or a heavy note on thick steel, if you test the pad before you trust it.
Less suitable: A child's fridge, a painted door you cannot mark, or a frame held only by the pad.
Specifications
Common questions
What pull does the listing claim?
The title and the pull field say 8 kg. They do not say that figure is on thick bare mild steel. Reviews describe them as very hard to separate.
Is adhesive included?
The highlight says double-sided adhesive. Reviews say the pads held on some metal and failed on picture frames and in a hot car.
Is there an age warning?
Yes. The listing says age 15+ only, and that the magnets are hazardous if swallowed or placed near medical devices.
BKSAI is twelve self-adhesive bars at £11.89, with N52 in the highlight, a 1.5 kg pull field, and 4.3 from 1,832 reviews. The pieces field says 1 while the title and unit count say 12, and the shape field says Round. A review says each bar is six very small magnets in a strip, so this is not one solid N52 bar. Some pads held a radiator cover and tools, and one buyer called the adhesive useless. Buy them when a light self-adhesive strip is the job and you can replace a failed pad. Skip them if you need a single magnet with a hole or a kilogram you can trace to thick steel.
Pros
Cons
Best for: A light self-adhesive strip for tools or a cover, if you can replace a pad that lets go.
Less suitable: One solid bar, a screw fixing, or a pull you need traced to thick mild steel.
Specifications
Common questions
Do they stick without screws?
The listing includes a self-adhesive backing and no screw holes. Reviews split: some pads held a radiator cover and tools, and one buyer called the adhesive useless.
Are they one solid magnet?
The bullet says several round magnets on one strip. A review says each bar is six very small magnets, so the 1.5 kg line is not a solid N52 bar.
What grade is printed?
N52 appears in the item highlight and in the colour field, which reads 12pcs N52. It is not a separate tested grade line.
MAGABALLNET is one hundred discs titled 5 mm by 2 mm at £5.99, with 4.3 from 1,089 reviews and a nickel-copper-nickel coating. The dimension field says 5 mm by 5 mm by 5 mm, so plan on the title and check the parcel. One verified review of two packs reported 92 and 95 magnets, which is one report, not a recount of every pack. No grade and no pull figure are printed. The bullet talks about strength for the size without a kilogram. At a similar price to the Wukong hundred-pack it is the weaker spec, because that other pack at least prints N48. Use it for small craft if a short count would not ruin the job. Do not use it where children can reach loose 5 mm discs.
Pros
Cons
Best for: Small craft on steel if a short count would not ruin the job and the discs stay boxed.
Less suitable: A stated grade, a full count you must rely on, or a kitchen where toddlers can reach the spares.
Specifications
Common questions
Is the count exactly 100?
The title and unit count say 100. One verified review of two packs reported 92 and 95 magnets. That is one report, not a recount of every pack.
What size should you plan for?
The title says 5 mm x 2 mm. The dimension field says 5 mm x 5 mm x 5 mm. Use the title millimetres and check what arrives.
Is a grade stated?
No. The bullet says the small magnets have great strength for the size, with no kilogram figure.
Shelf prices, stars and review notes are the eleven amazon.co.uk listings stored for this set, dated 21 October 2026. A magnetic stud finder was removed before scoring. This is not a lab test of pull, grade, coating or heat. Each score is the sum of four marks: a star line, that listing's own review sample, listing clarity, and a review-signal mark. The weights below are those marks scaled so they total 100. The number on each product is the unscaled sum. A review row shared by two ASINs scores as one thin sample, not two British samples. The highest score, 81, is the top pick. Best value is a separate award for a stated grade and a low price per disc. OPSS PSA1, BS EN 71-1 as used in that alert, and the Toys (Safety) Regulations 2011 are safety limits, not points on the score.
Star line
41%The amazon.co.uk star line is multiplied by eight and rounded. A 4.3 becomes 34, a 4.4 becomes 35, a 4.5 becomes 36, and a 4.6 becomes 37. Stars are not the whole score.
Review sample
21%The amazon.co.uk count on that listing adds 20 from 5,000 reviews, 16 from 2,000 to 4,999, 12 from 1,000 to 1,999, 8 from 200 to 999, and 4 from 50 to 199. A review row shared with another ASIN in this set scores 4, whatever count is printed.
Listing clarity
26%Clarity starts at 25 and loses marks for a missing grade, a missing or paper-only pull, a pull that does not name the surface, two pull figures, or a size, pack count, or shape field that fights the title. The floor is 0. The weight here is that mark's share of the method, scaled to 100.
Review signal
12%The mark is 12 when several notes name a job and a fault, 10 when the notes are useful but narrower, and 8 when the file is thinner or shared, then minus 3 when the fault changes the buy. The floor is 0. The weight is that mark's share, scaled so the four weights total 100.
You are choosing a disc, a block, an adhesive bar or a steel-cup pot. The job comes first: paper on steel, a glued pad, or a screw-fixed catch. On this amazon.co.uk capture, tiny disc packs sit around £3.99 to £5.99, mid-range packs and one specified N52 disc sit around £7.99 to £9.99, and twelve adhesive bars are about £11.89. Trust millimetres that match the title, a printed grade, and a pull that names mild steel. A star row shared across two sizes is one row.
A neodymium magnet in this category is a sintered NdFeB disc, block, adhesive bar, or steel-cup pot, sold as a multi-pack for a fridge, a whiteboard, or light DIY. The shelf is mostly bare discs: packs around 5 mm by 2 mm, 6 mm by 3 mm, and 10 mm, plus a wider 30 mm disc and one thick 20 mm disc. A bar may be a strip of small discs rather than one solid magnet. A pot is a magnet in a steel cup, with one working face and, on a countersunk pot, a screw through the face.
Photos make 5 mm and 6 mm discs look larger, and UK reviews say so. Read the title millimetres against the dimension field. If they disagree, measure what arrives before you cut a recess.
About 26 g of paper, an 8 kg line with no surface, and 14.8 kg flush on mild steel are not one measurement. A catalogue kilogram is straight off clean thick steel, not a fridge and not a safe working load.
OPSS PSA1 covers small high-powered magnets because two or more, swallowed, can cause serious injury or death. NHS pages say go to A&E and do not wait for pain. A “not a toy” bullet is not a certificate.
The millimetres decide the job. A 5 mm by 2 mm disc and a 6 mm by 3 mm disc are note magnets. A 10 mm disc is easier to find on a door. A 30 mm disc and a 20 mm by 10 mm disc are a different object. Photos in this category make the small discs look larger. Read the title against the dimension field. If those lines disagree, plan on the title and measure what arrives. Prefer a stated grade. N48 and N52 on a listing are claims, not a lab certificate, and a missing grade is a missing fact.
Loose discs need a steel surface, or glue you supply. A glued pad can fail on a frame or in a hot car even when the magnet itself is strong. An adhesive bar may be small discs in a strip, and the pieces field may not match the title. A countersunk pot takes a screw, usually with screws in the pack, and the steel cup gives one working face. Do not overtighten that screw. Nickel-copper-nickel slows rust. It is not a waterproof rating and not a child-safety mark.
Three typical situations, each with a recommendation from this comparison.
You want small discs for notes or light photos on a steel fridge or whiteboard, and you can store loose discs away from children. The walolo pack is the top pick: forty 6 mm by 3 mm discs at about £3.99, score 81, with 4.4 from 6,085 reviews. No grade and no steel pull are printed.
You want a lot of tiny discs for notes or craft, and you want a grade on the listing. Wukong is best value at about £5.94 for 100 discs titled 5 mm by 2 mm, with N48 on the bullet, score 80, and 4.5 from 4,341 reviews. The 26 g line is paper. The thickness fields say 5 mm, so measure one disc.
You need a screw-fixed catch, or a kilogram written against mild steel. VACUBXBY is six 20 mm by 6 mm pots with M4 screws at about £4.99. The pull lines say 25 lb and 20 lb, and no grade is stated. If the listing must print N52 and a mild-steel pull, FIRST4MAGNETS F646-N52-1 is one 20 mm by 10 mm disc at about £9.99.
The top pick is the walolo pack of forty 6 mm by 3 mm discs at about £3.99. It scores 81, the highest in this set, with 4.4 from 6,085 reviews, the largest review file here that belongs to one listing. No grade and no pull are printed, and the model field names a different product. It is not a lab test. Skip it when you need a stated steel pull, a screw, or a grade you can read on the listing. Best value is the Wukong pack of 100 discs at about £5.94, score 80, with N48 on the bullet and 4.5 from 4,341 reviews. The title says 2 mm and the thickness fields say 5 mm. The 26 g line is a paper claim. MAGABALLNET is about £5.99 for a stated 100 at a lower score, and the dimension field disagrees with the title.
Wukong 100 pack, 5 mm x 2 mm
About £5.94 for 100 discs, score 80, N48 on the bullet and 4.5 from 4,341 reviews. The 26 g line is paper.
