ELECTRIC AND MAGNETIC FIELDS FOR ELECTRIC (J) AND
MAGNETIC (M) CURRENT SOURCES:
 An electric current source J and a magnetic current source M. The
procedure requires that the auxiliary potential functions A and F
generated, respectively, by J and M are found first. In turn, the
corresponding electric and magnetic fields are then determined (EA,
HA due to A and EF , HF due to F).
 The total fields are then obtained by the superposition of the
individual fields due to A and F (J and M).
