Right Hand Rule 1 + 2

The Right hand rules are used to determine the direction of current and the north and south poles of a conductor or coil. The Right hand rule literally uses your right hand to measure these things. With a conductor, you wrap your right hand around it and bend your fingers in, similar to a 'cat'. The direction in which your thumb is pointing is the direction of the flow of current. The fingers symbolize the invisible magnetic field around the conductor.

This is known as the Right hand Rule.
