일반물리학 2 — Induction and Inductance: Problem 67

67 In Fig. 30-52, a 120-turn coil of radius 1.8 cm and resistance 5.3 \(\Omega\) is coaxial with a solenoid of 220 turns/cm and diameter 3.2 cm. The solenoid current drops from 0.42 A to zero in time interval \(\Delta t = 0.67\) s. What current is induced in the coil during \(\Delta t\)?
