Physics for IGCSE & O level - Magnets And Currents (Section 3 - No. 38)
How can the e.m.f. induced in a coil be increased?
Using a stronger magnet.
Increasing the speed of relative motion.
Decreasing the resistance of the coil.
Increasing the number of turns in the coil.
Erläuterung
Using a stronger magnet, increasing speed of the relative motion, and increasing the number of turns in the coil all increase the magnitude of the induced e.m.f.
