Flux linkage
H2 Physics · JC 2 · Hard · Flux linkage
A rectangular coil with 80 turns and area 2.0×10⁻³ m² is placed in a uniform magnetic field. The magnetic flux density through the coil increases uniformly from 0.10 T to 0.40 T in 0.020 s, with the field always perpendicular to the plane of the coil. What is the magnitude of the average induced e.m.f. in the coil?
