Hey all, I was wondering about a varied version of something.
I know that if you run a magnet up and down a tightly coiled tube of copper, it creates an electric current through the wire. I also know the reverse, which is that if you passed a current through that wire, while it was wrapped around a ferrous or magnetic substance, it will become magnetized (an electromagnet).
What I was wondering, is that would this still apply, if you replaced the ordinary magnet with a magnetic ball, still running it up and down the tube. (Assuming) the ball would roll over going both ways, with its poles moving around, would an electric current still be produced in the copper wire? Or would the poles have to be in the same position all the time?
