  • The Motor Effect
    • The force experienced by a current-carrying wire in a magnetic field
    • Size of force increases by
      • Increase the current
      • Stronger magnet
    • Size of force depends on angle between wire and magnetic field lines; the force is:
      • Greates t when wire is perpendicular to magnetic field
      • 0 when wire is parallel to magnetic field
    • Direction of force reversed if direction of current/magnetic field is reversed
      • thuMb = Motion
        • First finger = Field
          • seCond finger = Current
