What is magnetization

Short answer

Magnetization M is the magnetic dipole moment per unit volume (A/m). It quantifies the net alignment of atomic magnetic dipoles and is related to the fields by B = μ₀(H + M), with M = χ_m H for linear materials.

What do you understand by the term magnetization?

Magnetization M is the magnetic dipole moment per unit volume of a material: M = lim (Σ m)/Δv as Δv → 0, in A/m. It measures how strongly the atomic magnetic dipoles in a material are aligned by an applied field. It is related to the field by B = μ₀(H + M), and for a linear material M = χ_m H, where χ_m is the magnetic susceptibility.
