Due to a small magnet, the intensity at a distance \(x\) in the end-on position is \(9~\text{gauss}\). What will be the intensity at a distance \(\frac{x}{2}\) on equatorial position?
1. \(9~\text{gauss}\)
2. \(4~\text{gauss}\)
3. \(36~\text{gauss}\)
4. \(4.5~\text{gauss}\)

At the magnetic equator, the angle of dip is

1. 0$°$

2. 90$°$

3. 45$°$

4. 135$°$

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:
1. \(M_B=8M_A\)
2. \(M_A= 4M_B\)
3. \(M_A=8M_B\)
4. \(M_A=2M_B\)

Magnetic screening is:

1. Not possible

2. Possible using superconductors

3. Possible using the iron ring as cover

4. Both (2) & (3)

The apparent dip at a place is always greater than or equal to the value of true dip at that place. This is due to

1.  An increase in the apparent value of B_V

2. A decrease in the apparent value of B_H

3. An increase in the apparent value of B_H

4. Both (1) & (2)

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

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$°$
