Ultra High Performance N52 Neodymium Magnet for Arts, Crafts, Model Making, DIY, Hobbies, Office, and Home - 10mm dia x 5mm thick - 3.2kg pull - Pack of 10

I also wrote a review of the N42-strength ones, noting how strong the adhesion is. These are incredible magnets - so STRONG. Small but oh so mighty! I'm hoping they work for the project I need them for, but they might be just too strong! - I will buy weaker ones as well, even though I wanted really strong magnets in the first place - be careful what you wish for lol. Perfect for anyone wanting incredibly strong magnets!!!

Strong and useful.

Bought 10 of these that came stored in a plastic box and had metal caps on the ends on the magnets to keep them safe. These ones are amazing, genuine article and SUPER strong. Liked them so much I order another 10, these came from a third party, just 10 magnets in a bubble envelope. Not the same as the real deal, no where near as strong. I know, I've just tested them side-by-side. Will be returning these ones. Check you get the genuine article!

These things stick like magnets. For their size, the strength of the bond is remarkable. That's great once you've got them in position but the road there is frought with broken fingernails, sore fingers, swearing and other such displeasure when all they want to do is not go where you want them to, and to stick to themselves. Firstly, put the magnets (and anything remotely ferrous) that you're not using into a different room, or even house. The number of times they try to regroup like the T-1000 is tedious and separating them from each other for the 43rd time is no joke. Also, they're rather brittle and the closing speed of 4300mph on impact when they regroup can cause a bit of damage. If someone invents a magnet separator/applyer, they'll be rich.

Don’t let you fingers get trapped in these extra strong magnets, despite their deceiving small size.

Wow! I didn't expect them to be quite so strong. Fridge magnets are continually dropping off the fridge because the cards/appointment letters are so thick the magnetism doesn't work. These are so strong they are in danger of tearing the letters if you are not careful. The best way to get the papers out is to turn the magnets on their side and roll the paper out from underneath before putting the magnet flat again. The other use I have for them is to hold my tools on a flat tin surface in the shed. Much more handy than having spring clips or having slots/holes in bits of wood. Fortunately I don't have a pacemaker so carrying them in my breast pocket will not affect it, but there are sufficient warnings against that, and the plastic enclosure box avoids accidentally carrying them individually. More than satisfactory, but don't be tempted to try them for toys. These are serious business tools.

N52 magnets are the strongest grade and these are definitely N52 with 14800 gauss. They require a LOT of effort to separate them and grip them so much better than cheap magnets sold on Amazon which are the weakest grade of N35 at 12200 gauss. If you need a strong magnet, these are great (I have bought 2 lots now as the first were so useful)

Very strong magnets for their size and suitably packaged. Beware to keep your fingers well clear! One magnet did crack on me but I was using mole grips a little too tight so no surprise there - that was my fault. make sure to buy the correct spec of magnet for your project as they come in a range of sizes and strengths.
