Right hand rule:

• For conventional current flow grasp the conductor with the thumb of the right hand pointing in the direction  of  conventional or positive, current flow. The curved fingers point in the direction of the magnetic field around the conductor.

• Grasp the conductor with the right hand such that curved fingers point in the direction  of  conventional or positive, current flow. The thumb points in the direction of the magnetic field within the coil. Outside the coil, the thumb represents the north end of the electromagnet produced by coil.
