A closely wound solenoid of 2000 turns and areaof cross-section 1.5 × 10–4 m2 carries a currentof 2.0 A. It suspended through its centre andperpendicular to its length, allowing it to turn ina horizontal plane in a uniform magnetic field 5 ×10–2 tesla making an angle of 30° with the axis ofthe solenoid. The torque on the solenoid will be:
  • a)
    3 × 10–2 N-m
  • b)
    3 × 10–3 N-m
  • c)
    1.5 × 10–3 N-m
  • d)
    1.5 × 10–2 N-m
Correct answer is option 'D'. Can you explain this answer?

Torque on the solenoid is given by ζ = MB sinθ where θ is the angle between the magnetic field and the axis of solenoid.
M = niA
∴   ζ = niA B sin 30°
= 1.5 x 10-2 N-m
