#### Magnetic susceptibility

In electromagnetism, the magnetic susceptibility (Latin susceptibilis, "receptive"; denoted ) is a measure of how much a material will become magnetized in an applied magnetic field. Mathematically, it is the ratio of magnetization M (magnetic moment per unit volume) to the applied magnetizing field intensity H .
