Magnetic dipole moment is a vector quantity directed from
1 south to north
2 north to south
3 east to west
4 west to east
Explanation:
A Magnetic dipole moment is directed from south to north. A magnetic dipole can be defined as the magnetic north pole and the magnetic south pole separated by a small distance.

Which of the following materials is repelled by an external magnetic field?
1 Iron
2 Cobalt
3 Steel
4 Copper
Explanation:
D Copper is a diamagnetic element so it will repelled by an external magnetic field.

The null points are on the axial line of a bar magnet, when it is placed such that its south pole points:
1 south
2 east
3 north
4 west
Explanation:
C The point at which resultant magnetic field intensity is zero that point is known as null point. When the north pole of bar magnet points geographically north, the null points are formed on equatorial lines at two points, where magnetic fields lines from the bar magnet (directed north to south) are cancelled by magnetic field lines by the earth magnet.

When a magnet is heated
1 it loses its magnetism
2 it gains magnetism
3 it neither loses nor gains magnetism
4 none of these
