4r Two circular coils X and Y have equal number of turn 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 then X9 Y 1 W By 1 Bx 3 By Bx 1 2 X 4 V 40 2 4 By Bx By Bx 2 x 4
