Q State Fleming's right hand rule.
Fleming's right hand rule
The middle finger, the forefinger and the thumb of the right hand are held in the three mutually perpendicular directions. If the forefinger points beside the direction of the magnetic field and the thumb are along the direction of motion of the conductor then the middle finger points in the direction of the induced current. This rule is as well called generator rule.
