The magnetic moment of a bar magnet of length 0.2m is `1 Am^(2)`. If it is cut into two equal pieces along its axis, what is the magnetic moment of each piece.

Explanation

To solve the problem, we need to find the magnetic moment of each piece after a bar magnet is cut into two equal halves along its axis.

### Step-by-Step Solution:

1. **Understand the Magnetic Moment Formula**:
The magnetic moment \( M \) of a bar magnet is given by the formula:
\[
M = m \times l
