Three Right Hand Rules of Electromagnetism – Magnetic Force

Teaching electricity and magnetism is complicated by the challenge that the magnetic forces are perpendicular to the motion of the particles and currents.  This requires a three-dimensional perspective which can introduce a variable of a “wrong” direction.  To prevent errors, let us be “right” and use the right-hand rule.
