Q-1: a) Define the pointing vector in term of its unit. (2) b) The electric and magnetic fields are define as E(x, y, z. t) = xĖ, (2, t) and B(x,y,z,t) = y B,(z, t), respectively. What is the direction for the pointing vector S? (2) c) Is the electric field E(x, y, z. t) = xEo cos(kor-wot) satisfies the Maxwell wave equation? A proof is required. (3) d) Arbitrarily, the relation between the electric and magnetic fields of an electromagnetic is defined by the differential equation, OB=OF. If the ex- pression for the electric field is similar to one defined in c), relate E with B quantitatively. (3) dr e) On the basis of vector calculus show that the differential equation VXE = -B of the Ampere circuital law is incorrect. Have a comment in short on the missing term. (2) f) In analogy to Maxwell-Ampere law of electromagnetic induction define differential equation for magnetic charges. (2)
