Define magnetization. Write its S.I. unit and dimensions.

Explanation

### Step-by-Step Text Solution:

1. **Definition of Magnetization**:
Magnetization is defined as the net magnetic dipole moment per unit volume of a material. It quantifies how much a material can be magnetized in response to an external magnetic field.

2. **Mathematical Expression**:
The magnetization (M) can be expressed mathematically as:
\[
