DIYMAG Powerful Neodymium Bar Magnets, Rare-Earth Metal Neodymium Magnet, N52, Incredibly Strong 33 LB Strength - 60 x 10 x 5 mm, Pack of 30

Easy to handle. Very strong magnet, worked very well for my application. Probably over-kill, but when did I ever let that stop me. Great thing to keep around, because, when you have this kind of capability, it opens up a whole new world of possibilities. Well worth the money. If you follow the directions, in initially separating them, there will be no worries about breaking them. But, I repeat they are very strong, and it will be very hard to pull them off of a surface- you have to slide it off an edge to remove them.

These magnets are great. The key to getting them apart is to slide it. Push the bottom of the outer one up so it slides above the rest enough to grip, then slide it of the rest of the way off working it to the side and out. Do not try to lift it off. Yes they are so strong they will crack if not handled correctly. The plastic dividers allow for easy sliding - just make sure you don't let go till it's away from the rest.

They do what they should. Strong for the size.Super glued a couple of washers to the back of a sound bar, 2 magnets is all it took to hold it up inside the top flap of my toolbox. Pretty slick. Used to hold some fine mesh over a vent that bees were taking to. Lots of uses. Nice painted finish to help prevent corrosion. Will buy again when they’re all used up.

I’ve used these magnets in a few different applications so far - I used two per little solar motion activated outdoor light, and those have seemed to work great so far. No signs of falling off at all and no signs of corrosion so far either. However, I then tried to use two to hold up a small bathroom organizer device/shelving thing, but luckily I hadn’t put anything in or on that shelf yet, because after a few days, the adhesive completely failed and the whole thing fell off. So, if you are hoping to support any more than a super lightweight item, I’d recommend getting stronger/better adhesive than what is included with these magnets. Other than that, the magnets work as expected!

Wanted these for a knife board. Was worried when they came in a box with resin and hardner when I opened the box they were perfect. No breaks and very strong for a small magnet.

These are quite strong but quite brittle as to be expected with these types of magnets. However the reason i took off two stars is because they are advertised as being "heat resistant". Well, they lost about half their strength after a few hours of exposure to 125 deg c. I encapsulated them in nylon then attempted to anneal the nylon with the temperature peaking at 125 deg c during the annealing process. After slow cooling over a few hours the magnets lost about half of their magnetism.

Literal garbage can’t even take a picture bc I threw them out. For starters it was ridiculous how hard it was to peel them apart from one another. So I guess that’s a positive the magnet is insanely strong. Infact so strong that while attempting to pull apart the top magnet strip it snapped and not just in a clean cut snap noooooo the one side had a smooth snapped edge but the other side was jagged and had a bunch of metallic shards break off into magnetic crumbs. At first I thought ok it was a fluke. Struggled trying to get the second stick detached until I’d had enough and grabbed the only tool I saw fit for the job, a dull butter knife. While pointing the magnet stick pile away from my face I slid the blade side of butter knife into the crack between the top magnet and the next one it was attached to and used my mini girl muscles to break the hulk like grip And it slid right apart right off the table and onto the floor, this time immediately cracking in half in a clean split down the center. (Incase anyone was curious-the centers are a grayish silver resembling graphite like the color of a sharpened pencils point and just have a thin black layer of paint.) So having only 3 sticks left in my pile...I grabbed some pillows and created a fort blockade (I was now determined) and successfully separated one stick from the other two went to test the sticky power of magnets foolishly on a magnetic piece of metal upside down I guess bc once it was within range of the metal surface it magically turned into an Olympic gymnast and preformed a backflip and attached to the metal surface. Not only did it preform acrobatics but it learned mitosis too bc it multiplied before my very eyes and instantly became two instead of one as it split down the center on impact. After that I saw enough and just chucked the rest. Save ur money

I gave it 5 stars because they are very strong magnets. It is the first time I have worked with magnets with this much power. I am making knife holders with them. The first time I used them I made a magnet train of 7 magnets. I tried to pick up the train and they snapped right out of my hand, sending one across the room and the others broke in pieces causing sparks to fly. I am not sure if they were suppose to shatter.
