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

Magnetization & Magnetic Intensity | Magnetic Properties
Magnetization, also termed magnetic polarization, is a vector quantity that measures the density of permanent or induced dipole moment in a given magnetic material. As we know, magnetization results from the magnetic moment, which results from the motion of electrons in the atoms or the spin of electrons or the nuclei.
