Definition of magnetic field susceptibility

Answer 1

In electromagnetism, the magnetic susceptibility (Latin: susceptibilis, "receptive"; denoted χ) is one measure of the magnetic properties of a material. The susceptibility indicates whether a material is attracted into or repelled out of a magnetic field, which in turn has implications for practical applications. Quantitative measures of the magnetic susceptibility also provide insights into the structure of materials, providing insight into bonding and energy levels.

Mathematically it is the ratio of magnetization I (magnetic moment per unit volume) to the applied magnetizing field intensity H.
