Question

A spherical shell with inner radius r1 and outer radius r2 is uniformly magnetized. Use Poisson’s relation to find the magnetic field B inside the inner surface of the shell, outside the outer surface of the shell and within the magnetized material of the shell. Use SI units.

Answer #1

A spherical shell with inner radius r1 and outer radius r2 is
uniformly magnetized. Use Poisson’s relation to find the magnetic
field B inside the inner surface of the shell, outside the outer
surface of the shell and within the magnetized material of the
shell. Use SI units.

A spherical shell, with inside radius R1 and outside radius R2,
is uniformly magnetized in the direction of the z- axis. The
magnetization in the shell is Mo = Mok. Find the scalar potential

A spherical dielectric shell has inner radius r1,
outer radius r2, and dielectric constant k. A charge Q
is placed at the center of the sphere.
(a) Determine the polarization P in the dielectric shell.
(b) Find the bound volume charge density, ρb, inside
the dielectric shell.
(c) Find the bound surface charge density, σb, at r =
r1 and r = r2.

A spherical, non-conducting shell of inner radius r1 = 7 cm and
outer radius r2= 16 cm carries a total charge Q = 18 nC distributed
uniformly throughout the volume of the shell. What is the magnitude
of the electric field at a distance r = 11 cm from the center of
the shell? (k = 1/4πε0 = 8.99 × 109 N.m2/C2)

Charge is distributed throughout a spherical shell of inner
radius r1 and outer radius r2 with a volume density given by ρ = ρ0
r1/r, where ρ0 is a constant. Determine the electric field due to
this charge as a function of r, the distance from the center of the
shell.
In this problem the volume charge density ρ is not uniform; it
is a function of r (distance from the center.)

An amount of charge Q is distributed uniformly inside a
spherical shell of inner radius a and outer radius b. Use Gauss's
Law to calculate the electric field at a distance r from the center
of the shell. Consider the cases r<a, a<r<b, and
r<b.
