Question

Two concentric coils, each with a radius of $2\pi$ cm, are placed at right angles to each other. If 3 A and 4 A are the currents flowing through the two coils respectively, the magnetic induction (in Wb m^-2) at the center of the coils will be:

$12 \times 10^{-5}$

$10^{-5}$

$5 \times 10^{-5}$

$7 \times 10^{-5}$
