  • 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
      • Increase the number of rotations: Increase Current, Stronger Magnet, Increase coils
      • Change the way of rotation: Change field or current
    • Loudspeakers
      • Magnet with a coil at the back
        • AC - one way goes up and one way goes down
    • Flemmings Left Hand Rule
      • ThuMb = Motion
      • SeCond finger = Current
      • Third Finger = Field
