The possible value of magnetic susceptibility of a diamagnetic material can be:

1. \(-2.45\)

2. \(0.75\)

3. \(-0.5\)

4. \(1.67\)

The bar magnet \(A\) of magnetic moment \(M_A\) is found to oscillate at a frequency twice that of magnet \(B\) of magnetic moment \(M_B\) and the same moment of inertia when placed in a vibration magnetometer. We may say that:

When a magnetic material is subjected to a very small magnetising force \(H,\) the intensity of magnetisation is proportional to:

If a bar magnet is kept on a horizontal plane with N-pole of bar magnet facing geographic N-pole and S-pole of bar magnet facing geographic S-pole, then the number of neutral points is:

The magnetization of a piece of iron or steel:

A Gaussian surface is drawn enclosing the N-pole of a bar magnet. The net magnetic flux through the Gaussian surface will be:
(pole strength of N-pole is treated as positive and S-pole as negative)

A material when heated suddenly changes its magnetic property at a particular temperature and above this temperature, its susceptibility is found to be inversely proportional to the absolute temperature. The material may be:

1. Ferromagnetic

2. Diamagnetic

3. Paramagnetic

4. Ferromagnetic or Paramagnetic

As we go from the magnetic equator towards the geographic south pole, the angle of the dip will become:

A long solenoid has 1500 turns per metre and an iron core of ${\mu }_r$ = 1100 is kept inside it. 2A current flows in the coil of the solenoid. If the core is heated beyond curie temperature, then:
