    Consider a long straight coaxial cable that carries a total current +I on its central conductor and - I on its concentric outer shell. Assuming that the current density on both conductors is uniform (though not necessarily the same value for both), find the magnitude of the magnetic field as a function of the radial distance s from the centre of the cable. Sketch a plot your result. For this particular problem, let the central conductor have a radius a...
