concentric thin
Consider two perfectly-conducting
cylindrical shells of infinite length with axes along
the z-axis and radii a and b (a < b). Current I flow
the positive z-direction in each shell. If the current
now flow in the positive z-direction in the inner shell
and in the negative z-direction in the outer-shell,
calculate the magnetic field in the three regions: (i) p
< a, (ii) a < p < b and (iii) p > b, where p = √x² + y².
Sketch the result for the magnetic field as a function
of the radial distance (p).
