Question

As the frequency increases, the flux inside the conductor will ________

Answer 1

The flux will definitely  increase.

Answer 2

Frequency and flux in a conductor relation can be explained by Faraday's law.

According to Faraday's law, the rate at which change in flux in a conductor takes place is equal to emf induced in the conductor.

or e= -dΦ/dt => dΦ= e. dt

We know time is inversely proportional to frequency f. So dΦ= e/f.

So we can conclude that with increase in frequency, flux also increases. Flux due to magnetic field is directly proportional to time integral of voltage applied. Increase in frequency means time integral of AC voltage becomes shorter and thus flux generation start diminishing.
