How does the (i) pole strength, and (ii) magnetic moment of each part

1.	How does the (i) pole strength, and (ii) magnetic moment of each part of a bar magnet change if it is cut into two equal pieces transverse to its length? [HOTS]
Answer» where M=Magnetic moment. According to this relation, when a BAR magnet is cut into TWO HALVES ALONG its length, area of cross-section become HALF. But length remains the same. So, the pole strength actually becomes half and consequently the magnetic moment becomes half
