Question

(a) Describe how the concept of "magnetic vector potential" may be introduced by considering the Helmholtz the orem of vector fields. What are and would their existence have any impact on the application of the vector potential? 4. magnetic monopoles [6] why the electric field is given in general by (b) Explain, as fully as you can, [7] дt (c) Show that the flux threading a path P is related to the vector potential A, by А. di, and then use this to find the vector potential on the inside of a solenoid, at a distance s from the axis. The solenoid carries a current I and has n turns per metre [7]
