No, it only consists of straight lines. The emf is zero before the coil enters the field, and then whilst in the field the emf stays constant (constant change of flux). The bit I don't get is that it says on the mark scheme that there should be a negative emf (the emf apparently changes direction half way through the motion) But the direction in which the flux is cut is always the same, so I don't get that?
