    Find the magnetic field at a distance r from the center of a long wire that has radius 3.13 mm and carries a uniform current per unit area 208 A/m^2 in the positive z direction.

    A.) First find the magnetic field, B out (r) , outside the wire (i.e., when the distance r is greater than ) at a point 6.08 mm , from the center of the wire.

    B out (r) = __________ T.

    B.) Now find the magnetic field B in (r) inside the wire (i.e., when the distance is less than ) at a point 2.08 mm , from the center of the wire
