From the potential pair one can also find the charge-current source that generates the fields. The potentials in a region of empty space are described by the following equations; (c) i) V(x,y,z,t) = 0, A(x,y,z,t) = ii) Mok 4c 0, -(ct-|x|)²k, for x < ct where the constant k = 26.5 A/sm, c is the speed of light and t is time in ns. i) Determine the electric and magnetic field from the potentials. ii) Determine the charge-current source that generates these fields. iii) Discuss the situation where |x|> ct. for |x|> ct Write and explain briefly the Jefimenko's equations. Describe briefly the extra information needed about the charge-current source before you can apply the Jefimenko's equations. iii) Which gauge transformation would be satisfied by the solutions of Jefimenko's equations?
