suppose a magnetized material has a magnetic dipole moment per unit volume
M in which the microscopic single dipole moment is m as shown in the figure
show that the potential of this object is the same as would be produced by
a volume current Jb throughout the material and a surface current Kb on
the boundary(hint: you may find it useful to consider the vector field given
by v×c wherec is a constant vector)
請寫過程謝謝
