Long, straight conductors with square cross section, each carrying current I, are laid side by side to form an infinite current sheet with current directed out of the plane of the page (Fig. 28.65).A second infinite current sheet is a distance d below the first and is parallel to it. The second s beet carries current into the plane of the page. Each sheet has n conductors per unit length. (Refer to Problem 28.81.) Calculate the magnitude and direction of the net magnetic field at
(a) point P (above the upper sheet);
(b) point R (midway between the two sheets);
(c) point S (below the lower sheet).
