PHXII05:MAGNETISM and MATTER

360601 A thin bar magnet of length \(2 L\) is bent at the mid-point, so that the angle between them is \(60^{\circ}\). The new length of the magnet is

1 \(\sqrt{2} L\)
2 \(\sqrt{3} L\)
3 \(2 L\)
4 \(L\)
PHXII05:MAGNETISM and MATTER

360602 The magnet dipole moment of a short magnetic dipole at a distant point along the equator of magnet has a magnitude of \('X'\) in SI units. If the distance between the point and the magnet is halved then the magnitude of dipole moment will be

1 2\(X\)
2 \(\dfrac{1}{2} X\)
3 \(X\)
4 \(\frac{1}{8}X\)
