Generators and Motors

1. What is electromagnetic Induction? (694-695)

• The process of inducing a current in a circuit by changing the magnetic field. 
• Potential difference of electrons and circuits
• Gravitational force and magnetic force.
• Electromagnetic waves and magnetic waves.

How can you induce a current in a closed loop of wire (circuit)

• By rubbing it vigorously
• By moving it towards or away from the magnet.
• By using a voltmeter to measure the current.
• The gravitational force that accelerates it downward.

What is a generator?

• The generator is a transformer
• A machine that converts electrical energy to mechanical energy.
• A device that converts mechanical energy to electrical energy.
• A generator is a DC current
