Becausse from Farday's law the voltage is induced due to the change in the flux of the circuit.
Hence if the flux changes the emf is generated and hence the current get flows to the circuit.
that is:
E = -d(flux)/dt
And if the flux is constant hence diffrentiation would be zero and the Emmf would be zero.
