True.
When a bar magnet is cut parallel to magnetic axis its pole strength and magnetic pole decreases.
∵
magnetic is cut parallel to magnetic axis, length remains the same, but
pole strength decreases accordingly as the poles are divided. so,
magnetic moment will also decreases accordingly.
Hence, option : A.
