A d-c surface current with density a x J s 0 flows in an infinite conducting sheet coinciding with the xy -plane.
a) Determine the magnetic flux density B at (0, 0, z) and at (0, 0, z ).
b) Find the vector magnetic potential A at (0, 0, z ) from B. Choose the reference zero potential at an arbitrary point z = z 0.
