Electric Motor

  • An electric motor is a machine which converts the electrical energy into mechanical energy.
  • Works on the principle that "when a current carrying conductor is placed in a magnetic field, it will experience a mechanical force" 
  • The direction of this mechanical force is as per Fleming's left hand rule.
