The aluminum ring hangs from a thin wire as shown in the attached picture below. Near the ring is the iron core of the electromagnet shown on the left side. Answer and justify: a. Does current flow in the ring in the described situation, and if so, in which direction when the Electromagnet is switched on? b. Is there current in the ring then, has the electromagnet been switched on for some time? In which direction does the current flow, if it does? c. Does current flow in the ring when the current in the electromagnet is cut off? In which direction does the current flow, if it does? please label your answer as a b and c
