Question

A capacitor with parallel circular plates of radius R = 1cm is discharging via a current of 10 Amp. Consider a loop of radius R/4 that is centered on the central axis between the plates.

(a) How much displacement current is encircled by the loop?

(b) Consider a new loop with radius r. At what radius inside the capacitor gap is the magnitude of the induced magnetic field half the maximum possible value? (maximum possible value can be written as a symbol)

(c) At what radius outside the capacitor gap is the magnitude of the induced magnetic field half the maximum probable value?
