Fleming’s Left Hand Rule

Fleming’s Left-hand Rule. Stretch out the First finger, second finger and thumb of your left hand so that they are at right angles to one another. If the first finger points in the direction of the magnetic field  and second finger points towards the direction of current, then the thumb will point in the direction of motion of the conductor.

Fleming’s Right Hand Rule

Stretch out the forefinger, middle finger and thumb of your right hand so that they are at right angles to one another. If the forefinger points in the direction of the magnetic field, thumb in the direction of motion of the conductor, then the middle finger will point in the direction of induced current.

This law is particularly suitable to find the direction of the induced e.m.f. and hence current when the conductor moves at right angles to a stationary magnetic field.
