Physics for IGCSE & O level - Magnets And Currents (Section 1 - No. 37)
In electromagnetic induction, when is the induced e.m.f. greatest?
When the magnet is stationary.
When the magnet is moving rapidly.
When the magnet is moving slowly.
The e.m.f. is always the same.
Maelezo
The induced e.m.f. is greatest when the rate of change of magnetic flux is highest, which corresponds to the most rapid movement of the magnet.
