H2 Physics · JC 2 · Medium · Flux linkage
A 120-turn circular coil of radius 4.0 cm is placed with its plane perpendicular to a uniform magnetic field. The magnetic flux density is increased uniformly from 0.10 T to 0.40 T in 0.060 s. What is the magnitude of the average induced e.m.f. in the coil?
- 3.0 V
- 0.30 V
- 1.5 V
- 9.0 V
