Question

Define magnetization. State its SI unit and dimensions.
 

Hint:

Magnetization quantifies the alignment of magnetic dipoles within a material.

Answer 1

Magnetization is a vector quantity that represents the magnetic moment per unit volume of a material. Denoted by \( \mathbf{M} \), it indicates both the strength and direction of the magnetic field within the material. 
The SI unit of magnetization is \( {A/m} \) (Ampere per meter), and its dimensional formula is: \[ [M] = [I L^{-1}] \] where \( I \) is the current and \( L \) is the length. \bigskip
