Neodymium??

#61
All of a sudden your stage sound drops to nothing, you turn around and see your cab sitting in a pool of pure liquid neodymium.

What there is to understand is that neodymium comes in powder form, which is encapsulated in metal capsules that are very thin and flimsy, they look like coins, that consist each in two plates glued or just assembled together. When required to magnetize, current is applied and the capsules get naturally hot , and burst if overheated, exposing the neodymium powder, a very messy situation if you ask me!

It's true that neo magnets are encapsulated in a thin coating of nickel/copper to protect them from moisture and oxidation. But the is no "powder" to escape.
The metallic powders for magnets are pressed under high heat/pressure and then sintered. The result is a ceramic-like homogenous mass.

Regular speaker cabs work for this too. Back in the 'old tech' days of samplers/keys that needed sounds loaded from disks, I had a keyboard player put his box of sample disks in the back of an open backed guitar amp for load in at a show...guess what was blank for the show that night. ;)

I knew a guy who used an Alesis Datadisc machine to play his backing tracks. He said he put his disks in the back of his amp one night and had no backing tracks the following night. I don't know if that true, or just a good story. I suppose that could happen.

BurningSkies. I recommend that you install a Gauss meter in the cabinet, so that you will be able to monitor when heat buildup in the motor causes a decrease in the strength of the magnetic field, and so be alerted that you should turn down the juice. Also, I recommend that you install a refrigeration system to cool your magnets. Oh, yeah, and ear plugs.

Did you just tell me to cool my magnets?

OMG! The voice of reason & scientific knowledge. I thought this entire thread was a spoof, but ..... :facepalm:

It is sad that our education system has allowed the most bizarre thought processes to be allowed out in the public. Where these ideas come from is truly puzzling, but as an old friend once said, ever mind is a different world.
