Magnetic Induction, Coefficient of

The number, obtained by dividing the magnetization of a body, expre ed in lines of force produced in it, by the magnetizing force which has produced such magnetization, expre ed in lines of force producible by the force in question in air. It always exceeds unity for iron, nickel and cobalt. It is also obtained by multiplying the coefficient of induced magnetization by 4 PI (4 * 3.14159) and adding 1. (See Magnetic Susceptibility--Magnetization, Coefficient of Induced.) 347   STANDARD ELECTRICAL DICTIONARY. The coefficient of magnetic induction varies with the material of the induced ma , and varies with the intensity of the magnetizing force. This variation is due to the fact that as the induced magnetism in a body increases, the magnetizing force required to maintain such induction, increases in a more rapid ratio. The coefficient of magnetic induction is the same as magnetic permeability, and in a certain sense is the analogue of conductivity. It is also termed the multiplying power of the body or core magnetized. It is the coefficient of induced magnetization (see Magnetization, Coefficient of Induced) referred to a ma of matter. For diamagnetic bodies the coefficient has a negative sign; for paramagnetic bodies it has a positive sign. Synonyms--Permeability--Multiplying Power--Magnetic Inductive Capacity.
