A long cylindrical conductor of radius 54cm carries a current. The current density is not uniform over the cross section of the wire, instead is is given as J = 7r. How much current is enclosed in an Amperian loop of radius 29? Note: If we had a uniform current, then we could simply multiply a current density by an area (pi r2) to get the current. Since we are dealing with a non-uniform current, we must instead take an...

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...
