A flat circular coil with 170 turns, a radius of 5.18 x 10-2 m, and a resistance of 0.497 Q is exposed to an external magnetic field that is directed perpendicular to the plane of the coil. The magnitude of the external magnetic field is changing at a rate of AB/ΔΕ = 0.966 T/s, thereby inducing a current in the coil. Find the magnitude of the magnetic field at the center of the coil that is produced by the induced current
