A current carrying coil experiences a torque due to a magnetic field. The value of the torque is 80 % of the maximum possible torque. The angle between the magnetic field and the normal to the plane of the coil is
Options
- A30^
- B45^
- C⁻¹ ( 3 4 )
- D⁻¹ ( 4 3 )
Correct answer
D. ⁻¹ ( 4 3 )
Step-by-step solution
the torque experience by a current carrying coil in a magnetic field is l = MB t _ = MB Also, l =80 % of i _ = 4 5 t _ = 4 5 MB MB = 4 5 MB = 4 5 = ⁻¹ ( 4 3 )
