Two identical soft iron rods are placed side by side. The north pole of a wide magnet is held close to the left-hand end of each rod. Both rods become induced magnets. Which statement correctly identifies the poles at their right-hand ends and the interaction between these ends?
Both right-hand ends are north poles, so these ends attract.
Both right-hand ends are south poles, so these ends repel.
One right-hand end is north and one is south, so these ends attract.
Both right-hand ends are north poles, so these ends repel.
