MOTOR
BOTH
GENERATOR
Name: Date: Period:
Changes electrical into mechanical energy.
Very useful and found in many everyday appliances.
Contains an electromagnet AND a permanent magnet.
Runs on electricity or battery
Contain permanent magnets and coils of wire.
Both spin.Are opposites.Both involve AC or DC current.
Changes mechanical energy into electrical energy.
Needs motion to operate.
Used in power plants to make most electricity used today.
Contain permanent magnets
