3. (a) We use Gauss’ law for magnetism:z⋅=GGBdA0 . Now, z⋅=++GGCΦΦΦ12, where Φ1is the magnetic flux through the first end mentioned, Φ2is the magnetic flux through the second end mentioned, and ΦCis the magnetic flux through the curved surface. Over the first end the magnetic field is inward, so the flux is Φ1= –25.0 µWb. Over the second end the magnetic field is uniform, normal to the surface, and outward, so the flux is Φ2= AB= πr2
