일반물리학 2 — Induction and Inductance: Problem 69

69 An electric generator contains a coil of 100 turns of wire, each forming a rectangular loop 50.0 cm by 30.0 cm. The coil is placed entirely in a uniform magnetic field with magnitude B = 4.30 T and with \(\vec{B}\) initially perpendicular to the coil's plane. What is the maximum value of the emf produced when the coil is spun at 1278 rev/min about an axis perpendicular to \(\vec{B}\)?
