A rectangular coil of length 0.12 m and width 0.1 m having 50 turns of wire is suspended vertically in a uniform magnetic field of strength 0.2 weber/m2. The coil carries a current of 2 A. If the plane of the coil is inclined at an angle of 30° with the direction of the field, the torque required to keep the coil in stable equilibrium will be:
- 0.20 Nm
- 0.12 Nm
- 0.15 Nm
- 0.24 Nm
Answer
(B) 0.12 Nm
