THE ELECTROMAGNETIC RESPONSE OF A MAGNETIC

Field experiments in the vicinity of a tabular body of nearly massive magnetite have demonstrated that the body may respond in either of two ways; it may react as a permeable mass, or it may react as an eddy current inductor, depending upon the frequency employed. If several frequencies, spanning a broad range, are employed, both types of response will be experienced.
