a: Electromagnetic induction ~
b: closed loop of tube filled with water
What:
"A chemical battery is like one full bucket and one empty bucket. Pour the water from the full bucket through the tube into the empty bucket, and you have current until the full bucket runs out.
Electromagnetic induction is like a closed loop of tube filled with water, with a motor-driven propeller inside. Turn on the propeller, and the water will flow around and around as long as you can supply power to the propeller."
