Is Copper Magnetic?

Whilst we are faffing about with magnets ....
 
     
 
Prof. Eric Laithwaite ... once went to one of his lectures .. much more amusing  for real ...  :)
 
Good bloke ...

Eric Laithwaite: absolute freakin' legend! :beer:

75Plus:
I became aware of the reaction of copper in a magnetic field about 50 years ago. I had a precision beam scale that was dampened by a copper vane moving between two fixed magnets. It was almost as efficient as a hydraulically operated damper.
 

Dawai:
Yes, slightly.. spinning a magnet close to a copper loop will heat it?

Water is slightly also magnetic. Diamagnetic? I think the word is? Water can exhibit anti-gravity "magnetic levitation" in the Lord Kelvins thunderstorm experiment.

     

The droplets "orbit" the coils as they transfer the electrical charge simulating anti-gravity.

TLGriff:
I used eddy current theory to build a magnetic damper for a scriber blade in a manufacturing fixture at work. The blade was oscillating as it was dragged across a plastic surface causing skips in the scribed line and the damper eliminated the oscillations. The damper was an aluminum disc attached to the scriber with a circular array of neodymium magnets in close proximity to it. As the magnets moved relative to the aluminum disc, they magnetized it, effectively damping the movement.
