A square circuit with an edge of a = 0.4(m) was composed of the R
resistance and the C capacitor. The circuit is placed in a magnetic field
perpendicular to its plane, as shown in the figure. Capacitor is empty at
t = 0. It is observed that the potential difference between the ends of the
capacitor changes with time t according to Vc = 12(1 - e^-t/τ) (V). Here
τ is any constant. Find the rate of change of the magnetic field.
