Find the force experienced by a pole of strength 100 Am at a distance of 20 cm from a short bar magnet of length 5 cm and pole strength of 200 Am on its axial line.

Explanation

To solve the problem of finding the force experienced by a pole of strength 100 Am at a distance of 20 cm from a short bar magnet of length 5 cm and pole strength of 200 Am on its axial line, we will follow these steps:

### Step 1: Understand the Formula for Magnetic Force
The force \( F \) experienced by a magnetic pole in a magnetic field is given by the formula:
\[ F = B \cdot m \]
where \( B \) is the magnetic field strength (magnetic induction) at the location of the pole, and \( m \) is the pole strength.
