4.30P) Magnetic dipole density of a material is M = M,ż + Mo/Rf Calculate the current densities, and total magnetic dipoles. a) If the geometry is a cylinder with length of L and radius ofR (In this case M = M,2 + M,/Rp and p is unit vector in cylindrical coordinates.). b) If the geometry of material is a solid sphere with radius R. (In this case M = M,2 + M,/Rf and f is unit vector in spherical coordinates.)
