One coil of resistance 4092 is connected to a galvanometer of 16099 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 32°C.
The magnetic field is:-
(1) 6.55 T
(2) 5.66 T
(3) 0.655 T
(4) 0.566 T
