5. The SI unit of magnetic flux is

1. Dyne
2. Tesla
3. Weber
4. Ohm

Explanation: The SI unit of magnetic flux is Weber.

6. Susceptibility is positive for

1. Ferromagnetic material
2. Paramagnetic material
3. Diamagnetic material
4. Option (a) and (b)

Answer: (d) Option (a) and (b)

Explanation: Susceptibility is positive for ferromagnetic as well as paramagnetic materials.

7. The magnetic dipole moment of a magnetic dipole is given by the formula ……………

1. M = m × 2I
2. M = m + 2I
3. M = m – 2I
4. M = m / 2I

Answer: (a) M = m × 2I

Explanation: The magnetic dipole moment of a magnetic dipole is given by the formula M = m × 2I. Where: m is pole strength and 2I is dipole length directed from S to N.

8. What is the formula to find the work done in rotating the dipole in a uniform magnetic field from θ1 to θ2?

1. W = MB (cos θ1/cos θ2)
2. W = MB (cos θ1 + cos θ2)
3. W = MB (cos θ1 – cos θ2)
4. W = M+B (cos θ1 – cos θ2)

Answer: (c) W = MB (cos θ1 – cos θ2)

Explanation: The formula to find the work done in rotating the dipole in a uniform magnetic field from θ1 to θ2 is W = MB (cos θ1 – cos θ2).
