While the object is moving towards the loop, a clock-wise current is induced in the loop, as viewed from above. Which of the following conclusions are accurate about the object and its orientation? 1) the object is magnetic, with its South Pole face closest to the loop 2) the object is magnetic, with its North Pole face closest to the loop 3) the object is magnetic, but there is not enough information to identify its magnetic poles 4) the object is not magnetic 5) there is not enough information to identify if the object is magnetic. CW The current in the straight wire is decreasing. What are the directions of the current induced in loop A, that encircles the wire, and in loop B?
