Subtopic: Magnetic Field Due to Circular Current Carrying Wire
Two circular coils X and Y have equal number of turns and carry equal currents in the same sense and subtend same solid angle at point O. If the smaller coil X is midway between O and Y, then if we represent the magnetic induction due to bigger coil Y at O as BY and that due to smaller coil X at O as Bx :

\[\frac{B_{Y}}{B_{X}} = 1\]
\[\frac{B_{Y}}{B_{X}} = 2\]
\[\frac{B_{Y}}{B_{X}} = 1/2\]
\[\frac{B_{Y}}{B_{X}} = 1/4\]
