Two concentric coils each of radius equal to 2π cm are placed at right angles to each other. 3 Ampere and 4 ampere are the currents flowing in each coil respectively. The magnetic induction in Weber/m2 at the centre of the coils will be (μ0 = 4π × 10−7 Wb/A-m)
(1) 12 × 10−5
(2) 10−5
(3) 5 × 10−5
(4) 7 × 10−5
