Physics · Moving Charges and Magnetism
A rectangular coil of dimensions 8.0 cm × 10 cm, with 100 closely wound turns, carries a current of 2.0 A. It is suspended vertically in a uniform magnetic field of 0.5 T such that the plane of the coil makes an angle of 30° with the field direction. The magnitude of the torque experienced by the coil is close to:
- 11.39 N·m✓
- 20.69 N·m
- 30.40 N·m
- 40.20 N·m
Correct answer
1.39 N·m
