Question
Nonuniform displacement-current density. The figure
shows a circular region of radius R = 5.0 cm in which
a displacement current is directed out of the page.
The magnitude of the density of this displacement
current is given by Jd = (9 A/m²)(1 - r/R), where r is
the radial distance (r ≤ R). What is the magnitude of
the magnetic field due to the displacement current at
(a) r = 2.5 cm and
(b) r =
= 6.5 cm?
(a) B =
i
(b) B=
T
R
