LOVIMAG Rare Earth Magnets, Small Magnets for Fridge, Whiteboard, Science, Crafts, DIY, Office and Locker Magnets-24pack

I recently got back into R/C after being out for more years than a lot of the readers of this, and I'm building a glider from a set of plans. Back in the day I would use a set of magnet to align and hold the ribs in place, instead of using pins, I bought these for that purpose.Now, the magnets I used back then were different, they were around 1" x 3/4" x 1/4", and were not NEARLY as strong as these. While these are much smaller, they would still serve the purpose...and that's where the title comes into play.As I said, the purpose of these was to stick one on each side of the rib to hold it square, and position it over the plans. With the older ones (which I searched for and cannot find any longer-and what drives me crazy is I KNOW I saw a package of them in some store!) there was no problem spacing out the ribs.Found out, REAL quick, not a good idea with these!I measured it - if you sit one of these on a slippery surface and take another one and hold it nearly 4" away from it, you can rotate the one in your hand and the one sitting there will rotate to match polarity.At 3" it will try to move towards your hand, and at 2 1/2" it will shoot across and slam into the one in your hand.If you separate them and let them fly at each other, though, they CAN, and DO shatter. I've had 2 do it already.If you're following along, you might guess that the ribs on a wing span of 50" aren't going to be spaced 5", at LEAST, apart, you may have imagined what happened with that.Fortunately no damage done, and I DID find a work-around by staggering each rib with the magnet at the front of the rib and the next on on the back. Managed to do what I needed.HOWEVER, the "annoying" part continues...Because they are so strong, pray there is nothing metal anywhere near them when you go to set them down somewhere.You know, things like x-acto knives, metal rulers, saws, pins, screws, blades, clamps, hinges with little metal pins, eyeglasses (grabbed the screws in the hinges), or any other magnetic object, because they WILL attack it!Since I have need to use them separately, it's necessary to space them where they won't all clump together, they when I go to use a tool the magnets will jump up and grab it as it passes over them.So it you NEED a strong magnet, these should do ya!

The purpose we bought for was good however the is quiet small which didn’t expect when we saw pics

After a day of him messing with them they started to chip. They are fun and he does like them but the chipping is a concern.

I bought these for my grandson who wanted them for his birthday, but we couldn't wait the extra 2 weeks! We've had so much fun...they are strong enough to be a challenge, but not so strong you can't get them apart. The only downside is that they will chip if they hit each other too hard. But I would buy them again!

these bad boys are strong. pack a lot of power for a small magnet. worked perfect for what we needed.

I've had two of these grenade because they grabbed each other.

These have a very strong pull. Be sure to be careful when handling Several people gave these a bad review because they break and that is because of improper handling. By the way, I chipped a couple myself

These magnets are quite strong, the finish on them is nice and they are easier to pull off because of their height than the flatter round ones.
