ELECTRIC MOTOR
... A change in magnetic field associated with a conductor will induce a electric current in the conductor. This phenomenon is known as electromagnetic induction. The direction of induced current can be found using Fleming’s right-hand rule. Stretch the thumb, forefinger and middle finger of right hand ...
