H2 Physics · JC 2 · Medium · Flux linkage
A rectangular coil of 80 turns and area 2.5×10⁻³ m² is placed in a uniform magnetic field. The magnetic flux density through the coil decreases uniformly from 0.20 T to 0.05 T in 0.10 s. What is the magnitude of the average induced e.m.f. in the coil?
- 0.30 V
- 0.075 V
- 0.15 V
- 0.60 V
