Two circular coils X and Y, having equal number of turns and carrying currents in the same sense, subtend same solid angle at point O. If the smaller coil X is midway between O and Y and if we represent the magnetic induction due to bigger coil Y at O as `B_y` and the due to smaller coil X at O as `B_x`,then find the ratio `B_x//B_y`.

Options

A. `(B_y)/(B_x)=1`
B. `(B_y)/(B_x)=2`
C. `(B_y)/(B_x)=1/2`
D. `(B_y)/(B_x)=1/4`

Answer

C
