A bar magnet of magnetic moment `10 A m^(2)` has a cross sectional area of `2.5 xx 10^(-4)m^(2)`. If the intensity of magnetisation of the magnet is `10^(6) Am^(-1)`, find the length of the magnet?

Explanation

To find the length of the bar magnet given the magnetic moment, cross-sectional area, and intensity of magnetization, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Given Values:**
- Magnetic Moment (M) = 10 A·m²
- Cross-sectional Area (A) = 2.5 × 10^(-4) m²
- Intensity of Magnetization (I) = 10^6 A/m
