Question
For a cylindrical conductor with a hollow center, let the radius from the axis to the inner circle be a and the radius from the axis to the outer circle be b, as shown below. Note that the region from the axis to a is hollow while the region between a and b is a conductor. We assume that the current I in the cylindrical conductor is uniformly spread into the cross-section between a and b. Plot the magnitude of the magnetic field with respect to the distance r from the axis.
