Suppose that a parallel-plate capacitor has circular plates with radius R = 23 mm and a plate separation of 3.8 mm. Suppose also that a sinusoidal potential difference with a maximum value of 110 V and a frequency of 85 Hz is applied across the plates; that is, V = (110 V) sin[2π(85 Hz)t]. Find Bmax(R), the maximum value of the induced magnetic field that occurs at r = R.
