Reasons for a greater induced emf (1 Viewer)

[OMGITzJustin]

I'm currently writing a discussion for a prac, and I'm currently struggling in finding information for specifics.
These are the ones that I'm most annoyed with:
I know that more turns of wire and a strong magnet both help maximise a greater induced emf, but what is the reason as to why those 2 factors help induce a greater emf?

Using the formula emf=-n(delta phi/delta time)
Therefore emf is proportional to number of winds, and delta phi/delta time (where phi is mag field strength x area), so if you increase the magnetic field strength or the area the emf increases. Also if speed of rotation increases delta time decreases hence increasing delta phi/delta time.

Overall: emf increases by: increasing the number of winds , increasing the magnetic field strength, increasing the area of the coil, increasing the speed of rotation.
