Abstract:
In a low intensity alternating magnetic field associated with Category L conditions, a heating agent being dispersed in, coated upon or otherwise associated with a host material to be heated to effect a defined operation on said host material by said heating agent which comprises:fibers including ferromagnetic material having magnetic permeability greater than 1; and whereinthe intensity of said alternating magnetic field is defined as low if a heating matrix including a 64% loading by weight of a 74-420.mu. iron powder is unable to heat said host material sufficiently to effect said defined operation in five seconds or less, and wherein said fibers have a heating efficiency of at least 150% of the heating efficiency of 74-420.mu. iron powder in a corresponding alternating magnetic field.
