The magnetic moment of a bar magnet is 45 `Am^(2)` and its length is 10 cm. Calculate the magnetic field induction at a point 10 cm away from the centre of the magnet on the axial line.

Explanation

To solve the problem of calculating the magnetic field induction at a point 10 cm away from the center of a bar magnet on the axial line, we will follow these steps:

### Step 1: Understand the Given Data
- Magnetic moment \( m = 45 \, \text{Am}^2 \)
- Length of the bar magnet \( L = 10 \, \text{cm} = 0.1 \, \text{m} \)
- Distance from the center of the magnet to the point where we want to find the magnetic field \( d = 10 \, \text{cm} = 0.1 \, \text{m} \)

### Step 2: Convert Length to Half Length
