Mateo drew the field lines around the ends of two bar magnets but forgot to label the direction of the lines with arrows. At left a rectangular box with the long horizontal side labeled S. At right a rectangular box with the long horizontal side labeled N. There is a gap between the boxes. Curved lines labeled 1 emerge from the right end of S and reach the left end of N. In which direction should an arrow at position 1 point?
