Right-hand rule #1: Hold the conductor with your right hand. Your thumb should be pointed in the direction of the conventional, or positive current flow. Your fingers should be pointing in the direction of the magnetic field around the conductor.

Right-hand rule #2(for coils): Hold the coiled conductor with the right hand such that the 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 north end of the electromagnet produced by the coil.
