JEE MainPhysicsMagneticsMCQ+4 / −1
Two concentric coils each of radius equal to 2πcm2\pi cm2πcm are placed at right angles to each other. 333 ampere and 444 ampere are the currents flowing in each coil respectively . The magnetic induction in Weber /m2{m^2}m2 at the center of the coils will be (μ=4π×10−7Wb/A.m)\left( {\mu = 4\pi \times {{10}^{ - 7}}Wb/A.m} \right)(μ=4π×10−7Wb/A.m)
