4 13 Two circular coils X and Y having 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 the bigger coil Y at O as B and that due to smaller coil x at O as B x then A C B V B B B 2r Y 0 25 1 X Figure 4 206 B D B B B y B X d 2 0 5 2
