**induced emf!**

Hello,

I am studying magnetic induction, induced emf, and faraday's law, that sort of thing. My book gives an example where the magnitude of a B-field is increasing at constant rate through an axis of a circular coil with N number of turns and a certain radius r, find the induced emf in the coil. However, in the solution, it says that the B-field is constant, and can be removed from the flux integral! How can this be possible, if it is increasing with time?

Thanks,

Stephen
