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).
