A hypothetical bar magnet (AB) is cut into two equal parts. One part is now kept over the other, so that the pole C2 is above C1. If M is the magnetic moment of the original magnet, what would be the magnetic moment of the combination, so formed? |

Answer» The magnetic moment of each half bar magnet is \(\frac{M}{2}\) but oppositely directed, so net magnetic moment of combination = \(\frac{M}{2}\) - \(\frac{M}{2}\) = (zero). |
