An infinitely wide flat sheet of charge flows out of the page in FIGURE CP29.83. The current per unit width along the sheet (amps per meter) is given by the linear current density J_s.

a. What is the shape of the magnetic field? To answer this question, you may find it helpful to approximate the current sheet as many parallel, closely spaced current carrying wires. Give your answer as a picture showing magnetic field vectors.
b. Find the magnetic field strength at distance d above or below the current sheet.
