Description:

About this item:

  • HIGH QUALITY: Made from strong neodymium-iron-boron alloy (NdFeB) and have a stylish nickel coating (Ni-Cu-Ni) with an appealing silver surface --- All the magnets are magnetized axially and have a maximal operating temperature of 80 degrees Celsius
  • MULTIPURPOSE: These neodymium magnets are perfect for DIY craft projects and scientific projects
  • LARGE SIZE: Diameter 40mm x thickness 20mm(approx.1.57"x0.79" ).Tolerances: ±0.2mm x ±0.2mm. Stronger magnetic properties and wider applications than ordinary magnets
  • USAGE TIPS: Neodymium magnets are not actually made of solid blocks of metal, but rather large amounts of powder pressed into blocks through a process called sintering. When subjected to a sudden impact, they will break. To prevent the magnets from breaking, the two magnets should be separated by a large distance to prevent them from being attracted and collided.
  • PURCHASE TIPS: If you purchased it to remove, please buy a combination of 2. The combination of 2 pieces has stronger magnetism. One piece of magnetic block can only be used for 85% of the labels on the market, and two pieces combined can be used for 98% of the labels on the market

    5.0 out of 5 stars Super strong!

    (function(){ P.when('cr-A', 'ready').execute(function(A) { if(typeof A.toggleExpanderAriaLabel === 'function'){ A.toggleExpanderAriaLabel('review_text_read_more', 'Read more of this review', 'Read less of this review'); } }); })() These worked awesome for what I needed them for. Zero complaints.Warning...don't let your kids play with these. Get a finger in-between then and they're in trouble. They probably couldn't get them apart, but if they did and get skin or a digit in them it's terrible. I speak from experience! They broke my skin and it took some effort to get them off.

    5.0 out of 5 stars Very strong

    I use these magnets to manufacture a gate latch for my elevator/lift. The magnets are so strong. I had to offset them to be able to get the gate open!

    5.0 out of 5 stars Insanely strong

    I bought them just to see how strong they really were. and they are definitely not a toy or anything to just play with. I have no clue what to use them for because the strength is scary. Keep away from kids for sure 😂 exceeded my expectations

    5.0 out of 5 stars Stronger than expected

    Did not work a leak to remove security tag from item. Bought item but store forgot to remove tag. I somehow lost the paper tag on the item AND the receipt🙄. Killing myself trying to figure out to get the tag off. so decided to buy this after seeing it on yt. complete Waste o’time! Wasn’t even strong enough to stick to the metal part of the tag

    4.0 out of 5 stars Great magnets! Very strong but very fragile.

    First, these are INSANELY strong magnets. I used them for a physics demonstration, and one of my students was not careful to empty their pockets before handling the magnet and it wiped the magnetic strip on his student I.D. in an instant. They will wreck havoc on your cellphone or computer. Not a toy by any stretch.These magnets are very difficult to separate, even if you are strong, and if they are anywhere near each other, they will come together so violently that they will chip or shatter each other. TAKE CARE! There is very little that you can do to keep these from smashing together once they are less than 5" away from each other. It hurts real pain to get your fingers involved between these. The little plastic spacer provided is not sufficient. I keep mine separated by a 1/2" thick piece of wood, and I can just barely get them apart that way when I want to use them.These are a great value though, super strong, and they perform better than I expected. Hours of fun with steel ball bearings or ferrofluid, and great for all kinds of demonstrations on magnetism.

    I bought a tigers jersey shirt from the store and I didn’t realize it had one of those ink tags on it. I had this top in my closet for months waiting for an occasion to wear it since it is white. I couldn’t take it back to the store cause I didn’t have my receipt still so I was searching for a magnet to take the tag off. I was shocked that it truly worked. I did it over the sink incase it busted the ink tag and I didn’t was my floor or anything else ruined it I made a mistake. But this magnet popped it right off. But be warned I wasn’t watching and it touched my sink and I had to pry it off by force. Also I would keep this in the box it comes in so that you don’t ruin anything by the magnet. Yes it was worth the money!!!!

    DO NOT, I REPEAT, DO NOT put your fingers in between these magnets. Only issue I've found is that, if your not careful, the magnets will smash together, and sadly, they will break. This happened to me when I was initially opening the package. I did NOT realize that the magnets would be as strong as they are. I finally was able to pry them apart, and immediately after, they shot back together as I relaxed (kind of user error) and broke into multiple different pieces. So if you buy these, just be careful with them and try not to put them too close to eachother.
