Consider a spherical shell with radius R and surface charge
density σ. By integrating the electric field, find the potential
outside and inside the shell. You should find that the potential is
constant inside the shell. Why?
A
spherical shell of radius a has a uniform surface charge density σ
and rotates with a constant angular velocity ω in relation to an
axis that passes through its center. In this situation, determine
the magnetic dipole moment μ of the spherical shell.
