Suppose that a parallel-plate capacitor has circular plates with radius r = 43 mm and a plate separation of 4.3 mm. suppose also that a sinusoidal potential difference with a maximum value of 120 v and a frequency of 72 hz is applied across the plates; that is,
v = (120 v) sin[2π(72 hz)t].
find bmax(r), the maximum value of the induced magnetic field that occurs at r = r.
