Magnetic flux#!#Induced emf

Does chanbe in magnetic flux induce e.m.f. or current ?

If the instantaneous magnetic flux and induced emf produced in a coil is phi and E respectively, then a according to Faraday's law of electromagetic induction

Asseration:Magnetic flux can produce induce e.m.f. Reason:Faraday establishid induced e.m.f. experimentally.

The magnetic flux linked with a coil (in Wb) is given by the equation phi = 5t^2 + 3t +16 . The magnetic of induced emf in the coil at fourth second will be

What is the change in magnetic flux produced in a coil in 25 s, if the induced e.m.f. In the coil is 2 mV ?

Magnetic flux linked with each turn of a 25 turns coil is 6 milliweber. The flux is reduced to 1 mWb in 0.5s. Find induced emf in the coil.
