Physics for IGCSE & O level - Magnets And Currents (Section 3 - No. 8)

Which of the following increases the magnitude of induced e.m.f.?

Increasing the strength of the magnetic field.

Decreasing the speed of the relative motion.

Increasing the number of turns in the coil.

Using a weaker magnet.

The magnitude of the induced e.m.f. increases with stronger magnetic fields and more coil turns. Reducing the speed decreases e.m.f.
