Question:
The capacitor in Figure is being charged with a 2.50A current. The wire radius is 1.50 mm, and the plate radius is 2.00 cm. Assume that the current i in the wire and the displacement current id in the capacitor gap are both uniformly distributed. What is the magnitude of the magnetic field due to i at the following radial distances from the wire's center:
(A) 1.00 mm (inside the wire),
(b) 3.00 mm (outside the wire), and
(c) 2.20 cm (outside the wire) what is the magnitude of the magnetic field due to id at the following radial distances from the central axis between the plates:
(d) 1.00 mm (inside the gap)
(e) 3.00 mm (inside the gap), and
(f) 2.20 cm (outside the gap)
(g) Explain why the fields at the two smaller radii are so different for the wire and the gap but the fields at the largest radius are not.
