LINEAR AC MAGNETIC-CIRCUIT THEORY

A theory is presented for linear, ac magnetic circuits. The theory dev elops real and imaginary reluctance terms which are used in the same m anner as real and imaginary impedance terms in linear, ac electrical c ircuit theory. The reluctance terms can be manipulated through coil-co upled resistances and capacitances. The theory is applied to a paralle l, magnetic-circuit configuration to show the limits of applicability for the particular materials from which the circuit is constructed.
