Where does the work you do pushing the magnet into the coil end up?
AJoule heat in the coil
BLight in the magnet
CSound in the air
DMass of the coil
Answer & Solution
Correct answer: A. Joule heat in the coil
1. The induced current flows through the coil's resistance.
2. Current through resistance produces heat.
3. The work becomes Joule heat.
