Magnetic material - a term commonly used to refer to materials, which are ferromagnetic or ferrimagnetic. Either of the two can also exhibit properties which are magnetically soft, hard, or semihard.

However, in general all materials are “magnetic” but they respond in various ways to magnetic field, depending on their atomic structure and ambient conditions. Even vacuum is “magnetic” because magnetic field can propagate through it and by definition its magnetic permeability is a universal physical constant.1)

Efficient energy transformation relies on magnetic materials The Taza power plant, photographed Nov. 2, 2008, in Kirkuk, Iraq, is the largest
and newest power plant in Kirkuk province.  The V94 turbine generator generates

There are several ways in which materials can respond, and these different types of response are described by various types of magnetism:
