Power from a moving aluminum-part? Answered
I was playing with some ideas and wonder if it is possible to get power from a moving piece of aluminum.
I know, if you tab the alu, you can get the power because to the eddy-currents geenrated if you have a permanent-magnet near...
But what if i wanted to get the power NOT from the aluminum, but from the "other" side like the magnet?
If i hold a magnet near a moving piece of aluminum, can i get power from the magnet as well or are the eddys only generated in the alu and not in the magnet since it already has its magnetic field?
So the basic question is:
How to get power with the help of a moving piece of aluminum, but the tab-point in NOT the aluminum but something geometrically separated.
Thanks a lot! :)
