Super Strong Neodymium Magnet N42 4 x 1/2 x 1/4 Permanent Magnet Block, The World's Strongest & Most Powerful Rare Earth Magnets by Applied Magnets

Got these to make a Vacuum cleaner , ferrous metals pickup bar. to pick (those last 2) screws off the floor and carpet before they shoot into the brush head. Keeps the vacuum from being destroyed, and now i can find them screws that always get as far away as possible :-)I am always being careful with the power there , but I still popped one, when it jumped.BTW , if you remove the shipping spacer, and connect these bars together lengthwise, you will need a good amount of strength to slide, rotate and separate them, without causing damage to the magnets or the person.Be safe.

These bad boys are STRONG. Well packaged and wrapped in thick bubble wrap and the two 4” long rare earth magnets are separated with a plastic shim. Naturally you will want to separate them right? Well be careful. They are very strong. And getting them back together separated by the plastic shim isn’t easy either. If you wanted STRONG smallish bar magnets you won’t be disappointed with these.

Got them stuck together and it was hard to separate them.

I ordered this for a makeshift gate latch, because believe it or not.. they don’t sell magnetic gate latches. Only electromagnetic.This magnet did the trick though, super strong magnet. Great purchase!

Purchased a kitchen knife strip holder with weak magnets, replaced them with these magnets. Knife strip cost less than these but dang does it work great now. So much for prime days?

I purchased these magnets for my sons science fair and I could not use them. When I received them the plating was lifted and cracked on almost all of the corners and the edges were extremely sharp. Once I got the magnets apart and we were setting up his Magnetic Accelerator the peices just kept chipping away and there were too many sharp edges. I decided that it was too dangerous for my son to use.

I have no dislikes about the magnet. However when I attached to another magnetic device I did not know the adhesion was that strong. I cracked the magnet in half. It is easier to remove now only because I attach only the end and than bend sideways to remove. VERY STRONG MAGNET

I've bought two of these, one for my hubby and one for my stepdad. It's so much easier to use than a handheld stud finder, plus it keeps screws and such from wandering away when working on projects.
