Inducing Electricity
How is electricity induced in a conductor of electricity (eg a wire or a coil).
What is the energy transfer?
When is a current induced?
If the magnet moves quicker should there be more current induced?
If the magnet were stronger how would this affect the current induced?
If there were more turns on the coil how would this affect the current induced?
How does the direction of motion affect the direction of the current?
Simple dynamo
When the wheel spins what happens to the magnet?
How does this induce a current in the coil?
Does the current flow in the same direction at all times?
Ac Generator
What is moving here?
What happens when the coil spins through 1800?
Why must there be brush contacts to the rings?
AC Output
How does the reading on the voltmeter change as the handle is turned?
Sketch the shape of the wave.
Speed of rotation
Compare the output of the two simulations
In what two ways does the speed of rotation of the coil affect the ac output?
