A uniform magnetic field B is directed into the page.
A circular circuit of radius r containing a
resistor R and a capacitor C, is placed in this field. Initially
the capacitor is uncharged, and at time t =
0, the magnitude of the magnetic field starts to change at a rate
dB/dt = x, x > 0.
a) Using Lenz’s law, determine the direction of the induced current
in the closed loop. Justify
your answer.
b) Calculate the induced...
