A flat circular coil with 178 turns, a radius of 2.24 x10-2 m, and a resistance of 0.539 Ω is exposed toan 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 ΔB/Δt = 0.797T/s, thereby inducing a current in the coil. Find the magnitude ofthe magnetic field at the center of the coil that is produced by the induced current.
