- Generating
- There is no current in a wire when it is stationary between the poles of a magnet
- The size of the voltage depends on the rate at which the magnetic field changes
- The brushes are contacts that touch slip rings and complete the circuit
- Slip rings are connected to the ends of the coil to allow the coil to spin without the wire winding around itself
- Increasing the speed of rotation of the electromagne-t increases the current induced in stator coils
- Stator coils rotate around the rotor coils and increase the frequency of the voltage generated
- As the coil rotates, the direction of the current reverses every half turn
- A voltage is induced when a magnetic field changes
- Reversing the direction of the magnetic field reverses the induced voltage and current
- When a wire is moved upwards, a voltage is induced and a current passes
