Suppose B in a region of space centered on the origin has cylindrical symmetry and is given by B = B, ộ where Bo is a constant, and ô is the azimuthal direction in cylindrical coordinates. i) What is the current density in this region of space? ii) Suppose the current density that you found extends out to a radius R and is zero for r>R. What is the magnetic field for r > R?
