Magnetic flux Ф is given by

Ф = ∫В. dA

dA is an element of area of the surface, the integration is carried over the entire surface through which we wish to calculate the flux. B is magnetic field.

If direction of coil is remained the same, area of the coil remains the same. But as we increase the magnetic field, the number of field lines passing through the coil increases. Therefore the magnetic flux will increase.
