A bar magnet with pole strength m and magnetic dipole moment p is cut into two identical pieces along its length. Then for each of the two pieces

pole strength and dipole moment are m/2 and p/2, respectively

The correct answer is Option (2) → pole strength and dipole moment are m/2 and p/2, respectively

When a bar magnet is cut along its length:

- Pole strength of each piece becomes half: $m/2$

- Magnetic dipole moment, being $p = m \cdot 2l$, also becomes half: $p/2$

Pole strength = m/2, Dipole moment = p/2
