Induced EMF graph problem

The magnet enters the coil and exits through the other side so that its south pole is down. The magnet has a constant speed of movement all the time. The coil is wound so that, viewed from "above", the wire moves in a counter-clockwise direction (picture). Sketch on the graph how the induced voltage will depend on the time seen by the voltmeter V (pay attention to the + and - poles of the voltmeter). Explain the answer! Will the graph be symmetrical with respect to some specific moment? Where will the magnet be at that moment? What is the asymptotic behavior of the graph (what happens when the magnet is very far from the coil)?
