Given below are two statements: 

Statement I:	\(\oint \vec{B} \cdot \overrightarrow{d s}=0\) because magnetic monopoles do not exist.
Statement II:	\(\oint \vec{B} \cdot \overrightarrow{d s}=0\) means the magnetic field is zero.

1.	Statement I is false but Statement II is true.
2.	Both Statement I and Statement II are true.
3.	Both Statement I and Statement II are false.
4.	Statement I is true but Statement II is false

Choose the correct statement regarding magnetism.

Soft iron is used to manufacture electromagnets because:

1. It has a high permeability.
2. Its retentivity and coercivity are small.
3. Its retentivity and coercivity are high.
4. Both (1) & (2)

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

At angle cos^{-1$\left(\frac{1}{\sqrt{3}}\right)$} to the magnetic meridian, the apparent dip is 60$°$. The true dip at the place is :

1. 30$°$

2. 45$°$

3. 0$°$

4. 60$°$

Elements of Earth's magnetism is/are

1. Magnetic declination

2. Magnetic Inclination (or dip)

3. The horizontal component of the earth's magnetic field

4. All of these

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

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)

The magnetization of a piece of iron or steel:

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:
