A loop of wire is supported so that it is free to rotate about a horizontal axis. Initially, the magnetic field is directed into the page and the current is clockwise in the loop, as shown. What modifications, if any, would need to be made to cause the wire to rotate around the horizontal axis? A The current would have to be changed to be counterclockwise. B The magnetic field would have to be changed to be out of the page. с The magnetic field would have to be changed so that it is directed either to the left or to the right. D The magnetic field would have to be changed so that it is directed toward the top or the bottom of the page. E No modifications are needed. The loop will rotate with the current and magnetic field in the directions shown.
