A long bar magnet has a pole strength of `10 Am`. Find the magnetic field at a point on the axis of the magnet at a distance of 5cm from the north pole of the magnet.

Explanation

To solve the problem step by step, we will follow the formula for the magnetic field due to a bar magnet at a point along its axis.

### Step 1: Identify the Given Values
- Pole strength (m) = 10 Am
- Distance from the north pole (d) = 5 cm = 0.05 m (conversion from cm to m)

### Step 2: Use the Formula for Magnetic Field
The formula for the magnetic field (B) at a point on the axis of a long bar magnet is given by:
