One coil of resistance 40Ω is connected to a galvanometer of 160Ω resistance. The coil has radius 6mm and turns 100. This coil is placed between the poles of a magnet such that magnetic field is perpendicular to coil. If coil is dragged out then the charge through the galvanometer is 32µC. The magnetic field is :–
- 6.55 T
- 5.66 T
- 0.655 T
- 0.566 T
Answer
(D) 0.566 T
