A bar magnet of pole strength (m) and magnetic moment (M) is cut perpendicular to its axis in two equal halves. The new pole strength (m') and magnetic moment (M') of each part are respectively:
- m and M
- m and \(\frac{M}{2}\)
- \(\frac{m}{2}\) and 2M
- 2m and \(\frac{M}{2}\)
Answer
(B) m and M 2
