Magnetization

This is the magnetic moment per unit volume. The units are the weber per meter squared [Wb/m²] or the tesla [T = Wb/m²] for SI units and the electromagnetic unit per square centimeter [emu/cm²] and the magnetization is expressed with the symbol I. 1 [Wb/m²] = 10⁴/4π [emu/cm²]. In the CGS units, the units of gauss [G] multiplied by 4π are often used and in this case, the magnetization is expressed with the symbols 4πI, giving 1 [T] = 10⁴ [G].
