A flat circular coil with 103 turns, a radius of 3.96 10-2 m, and a resistance of 0.456 Ω 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 = 0.704 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.
the answer is 0.00128T
can you show me the steps to get this answer? thank you
