Maxwell's right handed screw/ Cork Screw rule

The figure shows the screw rule used to determine the direction of the magnetic field in a current carrying conductor. It states that if a right hand screw is screwed into or out of a board, the direction in which it rotates is the direction of the magnetic field around the current carrying conductor if the direction of motion of the screw is the direction of current in the conductor.
This can be used to verify the right hand grip rule.
