Magnetic induction at an axial point of a short magnet at a distance \(r\) from the centre of dipole is \(\vec B\). Its value at the equatorial point of the short magnet at the same distance from the centre of dipole is:

1.	\(-\vec B\)	2.	\(\dfrac{\vec B}{2}\)
3.	\(\vec B\)	4.	\(\dfrac{-\vec B}{2}\)

Consider a magnetic dipole kept in the east-west direction. Let P₁, P₂, Q₁, Q₂ be four points at the same distance from the dipole towards north, south, east and west of the dipole respectively. The directions of the magnetic field due to the dipole are the same only at:
1. P₁ and Q₁
2. P₂ and Q₁
3. P₁ and Q₂
4. Q₁ and Q₂

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:

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)
