일반물리학 2 — Induction and Inductance: Problem 68

68 A loop antenna of area \(2.00 \text{ cm}^2\) and resistance \(5.21 \text{ m}\Omega\) is perpendicular to a uniform magnetic field of magnitude \(21.0 \text{ mT}\). The field magnitude drops to zero in \(2.96 \text{ ms}\). How much thermal energy is produced in the loop by the change in field?
