Please answer all parts. Equation 110 is given below for reference.

where 0 is the usual tangential unit vector in the x - y plane. So, for our cylinder of current, D' N. VX A = (110) C2 2 TEO 1 The result on the right-hand side is the expression for the magnetic field generated by a infinitely long cylinder of current.An infinitely long cylinder of radius, R, carries a constant current density, J = Jk. Using Ampere's law and taking advantage of the symmetries of the problem, evaluate the magnetic field as a function of transverse distance, r1 , from the z axis for r) R. Show that the latter result is consistent with Eq. 110 in your notes. Then, find an acceptable expression for the vector potential in the region 1
