The cylinder shown represents a cross-section of a long straight hollow wire with inner radius a and outer radius b. has current coming out of the surface. The magnitude of the current density is given by the equation J = Ar², where A is a constant and r is the distance from the center of the cylinder. Find the magnitude of the magnetic field at all points in space.
