Question:

Uniform displacement-current density figure 32-30 shows a circular region of radius R = 3.00 cm in which a displacement current is directed out of the page. The displacement current has a uniform density of magnitude Jd = 6.00 A/m2.What is the magnitude of the magnetic field due to the displacement current at radial distances?
(a) 2.00 cm
(b) 5.00 cm
