The correct answer is
<span>the flux increases because the magnitude of b increases.
In fact, the magnetic flux is given by
</span>
<span>Where B is the intensity of the magnetic field, A the area enclosed by the coil and </span>
the angle between the direction of B and the perpendicular to the area A.
We can see that since in the problem the intensity of B increases, and the direction remains unchanged, then the magnetic flux increases as well.
