Magnetism and Electromagnetism; Right Hand Rules

Oerstead' Principle; the charge moving through a condutor produces a circular magnetic field around the condutor.

RHR1
Grasp the conductor with the thumb of the right hand pointing in the direction of the conventional (positive) current flow. The curved fingers point in the direction of the magnetic field (around the condutor.)

RHR2
Grasp the coiled coductor, with the right hand. The curved fingers should point in the direction of the conventional (positive) current flow. The thumb should point in the direction of the magnetic field within the coil. The thumb also represents the north (N) end of the electromagnet produced by the coil.
