22. (a) Since G BB = ± i uniformly, then only the area “projected” onto the yz plane will contribute to the flux (due to the scalar [dot] product). This “projected” area corresponds to one-fourth of a circle. Thus, the magnetic flux Φ B through the loop is Φ B BdA rB =⋅ = z G G 1 4 2 π . Thus, 2 22 3 5 11
