Right Hand Rules #1 & #2

OERSTED'S PRINCIPLE: Charge moving through a conductor produces a circular magnetic field around the conductor

RHR#1



RIGHT-HAND RULE #1 (RHR#1) for conventional current flow: Grasp the conductor with the humb 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.



RHR#2



RIGHT-HAND RULE #2 (RHR#2) for conventional current flow: Grasp the coiled conductor with the right hand so 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 the north (N) end of the electromagnet produced by the coil.
