We can model a tightly packed solenoid as a tube having a current density J(r) = (a/s²) between an inner and outer radii R₁ and R₂. Here s and are the usual cylindrical coordi- nates, and a is a constant. Calculate the magnetic field along the axis of symmetry, choosing the origin of your coordinate system to be in the middle of the solenoid.
