Question

A circular conducting loop of radius 0.10 m lies in a region of uniform magnetic field perpendicular to its plane. The field magnitude increases at a steady rate of 0.50 T/s. Find the magnitude of the induced electric field (in millivolts per metre) at points on the loop's circumference.

Step-by-step solution

By Faraday's law in integral form, E*(2*pi*r) = |dPhi/dt| = pi*r^2*(dB/dt). So E = (r/2)(dB/dt) = (0.10/2)(0.50) = 0.025 V/m = 25 mV/m.

Final answer25.0
