A flat circular coil with 105 turns, a radius of 4.00 x 10 neg 2nd m, and a resistance of 0.48Ω 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 ΔB/Δt =0.783T/s, thus inducing a current in the coil. Discover the magnitude of the magnetic field at the center of the coil that is produced with the induced current.
