Currents, Ampérian

The currents of electricity a umed by Ampere's theory to circulate around a magnet. As they represent the maintenance of a current or of currents without the expenditure of energy they are often a umed to be of molecular dimensions. As they all go in the same sense of rotation and are parallel to each other the result is the same as if a single set of currents circulated around the body of the magnet. More will be found on this subject under Magnetism. The Ampérian currents are purely hypothetical and are predicated on the existence of a field of force about a permanent magnet. (See Magnetism, Ampére's Theory of.) If the observer faces the north pole of a magnet the Ampérian currents are a umed to go in the direction opposite to that of a watch, and the reverse for the south pole.
