일반물리학 2 — Induction and Inductance: Problem 51

51 A small loop of area 3.1 mm2 is placed inside a long solenoid that has 672 turns/cm and carries a sinusoidally varying current i of amplitude 1.28 A and angular frequency 212 rad/s. The central axes of the loop and solenoid coincide. What is the amplitude of the emf induced in the loop?
