Tragic accident with ball magnet EMDR motor-generator

[TinselKoala]

I wish I had access to my old lab. It would be really interesting to take a high-speed video of the magnet exploding from the inertial stresses. I used to be able to use a video camera that could take 30,000 frames per second. Oh well, maybe somebody up there is reading this and will try it.

What is your nearest University town, TK?

I would bet my bottom dollar that, if your gear is reasonably transportable, one of the engineering faculties will have the equipment and be entertained at the idea of setting up on their premises.

The real challenge is converting that speed to useable power.

It doesn't have to be big either.

Wow!! You mean if someone is an asshole to me, I can tell them to lick my left nut and not get banned!!?? This is the coolest Forum on the Internet!!

Hi All,
we again have to warn users using big sized Neodym ball magnets with high speed rotation !

Another member of a German group has been hit by flying apart pieces of such a 3 cm diameter ball magnet.

He got hit into his arm with several pieces and also a plexiglas piece flying into his eye,
fortunately it was no piece of the magnet, so his eye could be saved.
Here is a video, where he described what happened to him, in German language:

So please be very carefull, when you play with ball magnets.
They are only sinter-pressed together and at high speed they fly apart and act like
lethal dum-dum munitions.. !
Better don´t use them at all !

I hope you will see the danger now...

Regards. Stefan.
