Sergeant Magnet of the Electron Army

Another video in our Animated Series. The light switch goes on and Sergeant Magnet sets off to recruit loosely held electrons to answer the call. He trains them to move forward as the magnet moves sideways across the wire. Then he sends them on a long range mission where the wire narrows and they meet resistance. They bounce along through the filament losing energy and exciting the atoms to give off light. They wonder if resistance is useless after all.
