Solution

The correct options are
A The number of turns of the coil
C The rate of change of magnetic flux linked with the coil
D Area of the coil
In the process of electromagnetic induction, the magnitude of the induced emf depends on:
Magnetic strength of the core in the coil of wire. (stronger --> bigger emf)

Number of turns of wire in the coil (more turns --> bigger emf)

The cross-sectional area of the coil (bigger area --> bigger emf).

speed of magnet (fast you move the magnet) into/out of the coil. (Faster --> bigger emf)

But Faraday's law seems to not show all four of these:

induced emfE=NΔϕΔt.
