Brought these home from Texas. Neodymium magnets, created by SWRI. We used them in refineries & oil fields to generate guided wave signals. Thought they were lost when a Chevron trailer was stolen off I410 many years ago. Each one you see is a mated pair, & we fear them. They are nasty powerful, and wicked around anything ferrous. Stop watches, wipe out hard drives, & ruin monitors. I had to mate a pair that I found separated, & it brought back memories of how dangerous these things can be. "What are you going to do with them?" Someone asked. I dunno, but you could ring a threshold & laugh when the FBI gets their weapons torn out of their hands.

Powerfullllll, Yeah.  I have 14 of them that are 1x2x1/2 that and can dead lift 169 lbs. each.  Had to make a special wooden device to separate them.  Bought them out of Dallas and intend to use them for a magnet motor that I may eventually get around to!  😀

Watch those around your car and wrist watch if it is electric. Almost everything today electronic is affected by strong magnets as well you know.

Learned the hard way with small ones.  Never get your hand between them, they snap together hard and fast when there poles match up

The only way to transport these things is mated, and shorting bars across the back of the poles. They went in the travel case specifically built for them, to keep them separated. I wouldn't carry them in a vehicle otherwise, might screw up the operating computer. A new technique was developed, and we attached pure nickel strips to piping, then used an alnico mag to introduce a field. Wrapped our coils around that array & we had a useful signal. Much more portable, much safer, and we pushed the beasts off to a corner.

Thanks for the lesson. Most interesting.
