6.15 understand that a voltage is induced in a conductor or a coil when it moves through a magnetic field or when a magnetic field changes through it and describe the factors which affect the size of the induced voltage

- If you more a wire back and forth in a magnetic field or through a coil (solenoid), a voltage will be induced.
- Increasing the magnetic field strength, quickening the speed your moving the wire or increasing the number of coils, will all increase the voltage.
