- Electromagnetism
- Electric current in a conductor produces an electromagnetic field
- Electric Motor
- current goes through and the motion goes up
- Break in the circuit means that the current switches
- The motion goes down causing it to turn
- Break in the circuit means that the current switches
- Increase the number of rotations: Increase Current, Stronger Magnet, Increase coils
- Change the way of rotation: Change field or current
- current goes through and the motion goes up
- Loudspeakers
- Magnet with a coil at the back
- AC - one way goes up and one way goes down
- Magnet with a coil at the back
- Flemmings Left Hand Rule
- ThuMb = Motion
- SeCond finger = Current
- Third Finger = Field
