Unformatted text preview: HW 3 Phys5406 S03 due 2/19/03 1) In an inﬁnite sea of constant magnetization, M, a long cylindrical hole of radius R is
drilled. If the axis of the hole is perpendicular to M, ﬁnd the magnetic ﬁeld B both inside
and outside the hole.
2) A sphere of radius R and permeability µ is placed in a constant magnetic ﬁeld B0 . Find
the resulting magnetic ﬁeld inside and outside the sphere.
3) A spherical hole of radius R is scooped out of a large volume of dielectric described by
constant polarization P. Calculate the electric ﬁeld inside and outside the hole. Use this to
help evaluate the following the integral:
dΩ cos θ /r − r 
for the case r’=Rez and r < R. 1 ...
