An infinite, straight wire of radius r lies along the z-axis and carries current i in the ˆz-direction. if the current density varies as j ∝ s 2 in cylindrical coordinates, use amp`ere’s law calculate the magnetic field b(s) inside and outside the wire as a function of i, s, and fundamental constants.
