How does the magnetic moment and pole strength of the two parts of a magnet change if a magnet is cut into two pieces along its length?

Explanation

To solve the question of how the magnetic moment and pole strength of a magnet change when it is cut into two pieces along its length, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Magnetic Moment**:
The magnetic moment (m) of a bar magnet is directly proportional to its volume (V). This can be expressed as:
\[
m \propto V
