A positively charged sphere is suspended on the end of an insulated string in the region between two vertical, metal, parallel plates that are connected to a coil of wire. A magnet is suddenly thrust into the coil of wire, as illustrated below. Insulated string Plate I Plate II N S Positively charged ball The hanging sphere with a + charge needed to be charged before hanging it between Plates I and II. Explain how the sphere could have acquired this charge. Use all necessary physics principles, concepts, equations or diagrams. (2 marks) Fully discuss what happens when the bar magnet is thrust into the coil of wire. Your discussion should end with describing the motion (if any) of the charged sphere. Use all necessary physics principles, concepts, equations or diagrams. (4 marks)
