Please post neat and legible work and complete all parts. A typed solution is prefered, however either way will work. Please comment on each step and justify the answer.
Answer ALL parts! Thank you.
Name l. (75) In our block of instruction on electrostatics, we derived the surface density of bound charge and the volume density of bound charge by considering the electrostatic potential of a polarized medium. In the absence of any free charge, we got, P(r) V(r) dag' dr' 41E, where we defined ob P in (surface density of bound charge) (2a) p, E-V.P (volume density of bound charge) (2b) In a similar manner, in our block of instruction on magnetostatics, we derived the bound volume current density and the bound surface current density by considering the magnetic vector potential of a magnetized material. In the absence of any free current, we got, R (r) M (r) X n dr' dr da' (3) 41a where we defined, KDEMxn (surface density of bound current) (4a) JevxM (volume density of bound current (4b) Strictly speaking, these results, derived as they were by the above methods, are only valid in the case of statics, and are not generally valid in electrodynamics (due mainly to the neglect of retardation effects-see text chapter 10). How, then, can the above definitions for surface and volume charges and currents be used to formulate Maxwell's equations, which are valid in both the static and dynamic regimes? To show the validity of the above definitions, you will derive them directly from the definitions of the polarization and magnetization vectors without referring to any static potentials.Explanation / Answer
The pictures are very small and also rotated. they are hardly visible. Can you please upload the question again. with bigger pictures and also proper orientation.
