An electromagnet generates an induced current when a magnet oscillates within its coil. The electrons responsible for this current originate from the conduction band of the metal forming the coil. This mobility of electrons allows them to move freely from atom to atom, facilitating the flow of current. Understanding this principle is essential for grasping the functionality of electromagnets in various applications.

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?
