Input (English): The Landau-Lifshitz-Gilbert equation of motion may be used to analyze the multicycle variety of this phenomenon. One significant researcher of this phenomenon wrote Elements of Electrical Engineering as a supplement to his Alternating Current Phenomena that uses his phasor analysis of circuits. When plotting magnetization in terms of magnetic field strength, the coercivity and remanence of a permanent magnet may be seen on the graph associated with this phenomenon. The physicist that names an equation often modified by a term for sinusoidal excitation frequency, which multiplies a power of the peak flux amplitude to find the time-average loss due to this effect, is named Charles Proteus Steinmetz. For 10 points, name this phenomenon that is central to magnetic tape memory, that means "lagging behind," and whose loop demonstrates path dependence.
