The maximum torque on the magnet of length ` 2 xx 10^(-1)m` in a uniform magnetic field having induction `2 xx 10^(-1)T` is 10Nm. Calculate its pole strength.

Explanation

To solve the problem, we need to find the pole strength of a magnet given the maximum torque, the length of the magnet, and the magnetic field induction.

### Step-by-Step Solution:

1. **Identify the given values:**
- Length of the magnet, \( L = 2 \times 10^{-1} \, \text{m} \)
- Magnetic field induction, \( B = 2 \times 10^{-1} \, \text{T} \)
- Maximum torque, \( \tau = 10 \, \text{Nm} \)
