Explanation

### Step-by-Step Solution:

#### (i) Definitions

1. **Magnetization (M)**:
- Magnetization is defined as the magnetic moment per unit volume of a material. It quantifies how much a material becomes magnetized when exposed to an external magnetic field.
- Mathematically, it can be expressed as:
\[
