Q5: a) Find the magnetic vector potential A of an infinite solenoid with n turns per unit length, radius R, and current I. b): A steady current I flows down a long cylindrical wire of radius a (Figure below). Find the magnetic field B, both inside and outside the wire, if the current is distributed in such a way that is proportional to s, the distance from the axis. a↑
