Fleming’s Right Hand Rule
The forefinger, the middle finger and the thumb of the right hand are held in the three mutually perpendicular directions. If the forefinger points along the direction of the magnetic field and the thumb is along the direction of motion of the conductor, then the middle finger points in the direction of the induced current. This rule is also called generator rule.
Fleming’s Right Hand Rule also known as the Generator Rule this is a way of determining the direction of the induced emf of a conductor moving in a magnetic field.
