A Level Physics AQA concept help

I am confused regarding the practical involving the search coil.
In the CGP book, it shows 2 graphs for a rotating coil - one for magnetic flux linkage and one for EMF induced. It shows that when the field lines are perpendicular to the coil, magnetic flux linkage is at a maximum (and so EMF is 0).
But for the search coil practical, it states that EMF is a maximum when coil is perpendicular to magnetic field lines.
It it because for the search coil, it is not continuously rotating so there is no rate of change of magnetic flux linkage?
