The copper and the magnet....

Absolutely fascinating.. I'm going to buy a strong magnet and a copper tube and demonstrate this to some of my friends at work...We like to come up with little built in the garage type science projects to demonstrate scientific principles...particularly if they're not very obvious.

Take a copper tube and drop a ball bearing..it'll fall quickly.
Take a copper tube and drop a magnet, and it'll fall slowly..amazing.
I want to try it and show everyone.
 
I told a friend about this and sent him a link to the video. He came back with a piece of 1/2 copper tube and a rare earth magnet. Works as advertised.

Being curious, I wonder how much, if any, current is generated? And how would you measure it? Can't hook anything to the magnet, and the pipe is a conductor so no place for two leads. Maybe a few turns of wire around the tube?

I have a tool/screw fetching magnet, and about 3' of 1/2" copper pipe, I thought of trying it, but didn't get to it, I also have several lengths of heavy10-12 ga insulated wire....maybe wrap the outside and take the Fluke meter to it.....then try shorting out the loops and see what happens....
