A flat coil with a cross-sectional area ...

A flat coil with a cross-sectional area S and with N turns is placed in a magnetic field. The leads of the coil are connected to an oscillograph. When the coil is moved out of the lield, an induction emf is generated in it, and the oscillogram of this emf is shown in the figure. How do the maximal value of the emf, `in_(Im)` and the area under the curve depend on the rate with which the coil is moved out of the field?
