Left-hand rule:
electromagnetism, the left hand placed in a magnetic field, so that the magnetic induction lines vertical penetration of the palm, palm facing the N pole (fork into the point out), referred four fingers point to the current direction, the direction of thumb is that a conductor direction of the force.
Simple principle:
power conductor in a magnetic field magnet provided continuously driven by Ampere force, resulting in rotational movement.
Changing the magnetic field direction and the direction of the battery, wires inversion occurs.
