Give a short answer or mathematical expression for the following: (a) write down the maxwell's equations. which equation(s) must be modified if the magnetic monopoles (b) define magnetization in terms of magnetic dipoles in matter. what is its unit? (c) what is coulomb gauge? use it to show the normal component of the vector potential discovered? are must be continuous at the boundary of two materials. (d) use one of the equations in (a) (which one? ) to show that b is perpendicular to the wave vector k in a plane electromagnetic wave (easiest to use complex notation).
