As begin mathsize 11px style straight epsilon equals negative dϕ over dt end style

And Φ = NBA cos ωt

Therefore, begin mathsize 11px style straight epsilon equals negative fraction numerator straight d open parentheses NBA space cos space ωt close parentheses over denominator dt end fraction end style

As per above equation, induced emf depends on:

i. Number of turns (N).

ii. Area of coil (A).

iii. Angular velocity (ω) of the coil.

iv. Strength of magnetic field (B).
