Question

Magnetic susceptibility of a material is – 0.5x 10-5. If the material is subjected to magnetic field of intensity, 104 A/m, find magnetic moment per unit volume of the material and magnetic flux density of the material. Also, identify the type of magentism associcated to the material.

Answer 1

Answer:

The origin of the magnetic moments responsible for magnetization can be either microscopic electric currents resulting from the motion of electrons in atoms, or the spin of the electrons or the nuclei. ... Physicists and engineers usually define magnetization as the quantity of magnetic moment per unit volume.

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.
