The magnetic needle of a tangent galvanometer is deflected at an angle 30o.The horizontal component of earth's magnetic field 0.34 x 10-4 T is along the plane of the coil. The magnetic induction produced by the coil at its center is

1.96 x 10-4 T
1.96 x 10-5 T
1.96 x 104 T
1.96 x 105 T

detailed solution

Correct option is B

B=BHtanθ=0.34 x 10-4 tan30o=1.96 x 10-5 T;where tan300 = 13
