1. Electromagnetic Machines
Which way will these move?
What happens when you pass a current through a wire?
The Motor Effect
Why do wires carrying a current experience a force when placed in a magnetic field?
How can you tell which way the wire will move?
Applying this to a motor……
What does the coil of the motor spin?
How can you make it spin faster?
How can you reverse the direction of spin?
The Generator Effect
What is needed to induce a voltage in a conductor?
How can you change the size and direction of the voltage produced?
Ac generator
Dc generator
Why do we get a sinusoidal pattern for the induced voltage with the ac but not dc generator?
Add annotations to the diagram to the diagram to show why we need the split ring commutator.
