Fleming’s Left Hand Rule and the Motor Effect







When a wire carrying an electric current is moved in a magnetic field of a magnet the magnetic field induced by the wire reacts with the magnetic field of the magnet causing the wire to move outwards. Fleming's left hand rule helps you to predict the movement.

First finger - direction of magnetic field (N-S)
SeCond finger - direction of current (positive to negative)
ThuMb - movements of the wire

When a coil of wire carrying a current is placed in a magnetic field the coil turns.
This is called the motor effect.

  2. Did you know that in a magnetic field, a current-carrying conductor would meet force? It is known as electromagnetic force, or emf. This trait is important to all modern electric motors and generators. So we know there's a force operating on the current-carrying conductor, but how do we know which direction it's pulling? If only a simple process could be applied in almost every situation. Fleming left hand rule will suffice.

    Similarly, when a conductor is activated in a magnetic field, an induced current is present. Power direction may be easily found by applying Fleming Right hand rule.
