Physics for IGCSE & O level - Magnets And Currents (Section 9 - No. 45)
Which of the following describes the relationship between the induced e.m.f. and the rate of change of magnetic flux?
The induced e.m.f. is unrelated to the rate of change of magnetic flux.
The induced e.m.f. is inversely proportional to the rate of change of magnetic flux.
The induced e.m.f. is directly proportional to the rate of change of magnetic flux.
The induced e.m.f. is equal to the rate of change of magnetic flux.
Vysvětlení
The faster the change, the greater the e.m.f..
