일반물리학 2 — Maxwell's Equations; Magnetism of Matter: Problem 42

42 Figure 32-28 shows a closed surface. Along the flat top face, which has a radius of 2.0 cm, a perpendicular magnetic field \(\vec{B}\) of magnitude 0.50 T is directed outward. Along the flat bottom face, a magnetic flux of 0.70 mWb is directed outward. What are the (a) magnitude and (b) direction (inward or outward) of the magnetic flux through the curved part of the surface?
