Sagot :
Answer:
1.) A coil of wire becomes an ELECTROMAGNET when current passes through it. The electromagnet interacts with a permanent magnet, causing the coil to spin.
2.) For a motor the input energy is ELECTRICAL ENERGY and the useful output energy is mechanical energy. The generator is used to produce an electric current from rotational motion (on large scale power stations a turbine is used to provide this rotation).
Explanation:
1. ELECTROMAGNET
2. ELECTRICAL ENERGY
