Student Objective To explain how energy transformations produce electricity 1 Warm Up What are the 2 things needed to generate electricity?

2 Electric Motors An electric motor transforms electrical energy into mechanical energy.

3 The generator is opposite of the motor !

4 MECHANICAL ENERGY ELECTRICAL ENERGY

5 MOTOR BOTH GENERATOR Name: Date: Class: magnets coils magnet coil Pg Pg

6 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
