일반물리학 2 — Induction and Inductance: Problem 46

46 A wire loop of radius 25 cm and resistance 8.5 \(\Omega\) is located in a uniform magnetic field \(\vec{B}\) that changes in magnitude as given in Fig. 30-41. The vertical axis scale is set by \(B_s = 0.80\) T, and the horizontal axis scale is set by \(t_s = 6.00\) s. The loop's plane is perpendicular to \(\vec{B}\). What emf is induced in the loop during time intervals (a) 0 to 2.0 s, (b) 2.0 s to 4.0 s, and (c) 4.0 s to 6.0 s?
