Does an Electromagnet Create Charge?

[ajcoelho]

Homework Statement

Suppose you have a simple electromagnet. In the middle of the coil you have a magnet oscilllating. Thus, there will be an induced current in the coil. But where the electrons of this current come from? Do they come from the atoms that form the coil?

Yes. That's why you use a conductor to form the coil; the electrons come from the conduction band of the metal, which are mobile and can (more or less freely) move from atom to atom.
