While there would be some current inducted into the bulb, I think it doesn't quite tell the whole story. If you had another bulb and wire, that was strung parallel, but not connected on the (switch side) far end, flipping the switch ON would, by laws of relativity, for entire 0.5s necessarily have exactly the same effect on both bulbs, regardless whether or which one forms a circuit. All power transfer would be inductive/capacitative and one needs to lookup those formulas if one wants to know what will happen during the first 0.5s and some time after that. Logically then, if the lines were perpendicular rather than parallel, only turning back into a loop far away, the switch's effect on the bulb would be exactly¹ zero until the fields themselves are folded by the wire far away. ¹ counting imperfections, reflections etc - not too close to 0
