일반물리학 2 — Induction and Inductance: Problem 64

64 A uniform magnetic field \(\vec{B}\) is perpendicular to the plane of a circular loop of diameter 12 cm formed from wire of diameter 2.5 mm and resistivity \(1.69 \times 10^{-8} \Omega \cdot m\). At what rate must the magnitude of \(\vec{B}\) change to induce a 10 A current in the loop?
