As power goes through a wire, it makes it a magnet. The more power, the stronger the magnet. This in inductance. If you place your hand on the wire with your thumb out in the direction of the current, your fingers will represent the direction of the magnetic field.

Magnets have a "field" around them in which they work. You can see by how when a paperclip gets close enough to it, it will jump to the magnet. So, when a magnet moves inside of a wire loop, all of the electrons in the wire try to follow the magnet like a paperclip would. This movement of electrons is electricity! Great question!
