If there were no current in the wire running through the magnet, what could you do to induce an electric current?

If there is no current running through a good conductor, it's always because

there is no potential difference between its ends, so the electrons in it have

no incentive to go anywhere. If you want a current to flow, just create a potential

difference (a voltage) between the ends of the conductor. You can do that with

a generator, a battery, a solar cell, or some pieces of metal stuck into a moist

potato. As soon as you do that, those electrons wake up, and they all start trying

to fly away from the negative end of the conductor, toward the positive end.
