What is an electric motor?
How does a simple electric motor work?
An electric generator
What is an electric generator?
It flows in one direction then the opposite direction.
What is an alternating current?
Moving the wheels
How might an electric train use the spinning motion produced by the motor?
It turns the wire loop between two magnetic poles.
How does a simple generator work?
Always flows in one direction.
What is a direct current?
The electric motor
What cause the wire loop spin?
They have the same parts.
What do simple generators and simple electric motors have in common?
An alternating current flows in one direction then the next, and direct current always flows in one direction.
What is the difference between alternating current and direct current?
The shaft does.
What causes the wire loop to spin?
Wall outlets and computers. (etc.)
What devices have used that use direct current? Alternating current?
