Mateo drew the field lines around the ends of two bar magnets but forgot to label the direction of the lines with arrows. At lef
t 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?

left
right
up
down
Answer:
The correct answer is
Left
Explanation:
Magnetic circuits describe the path of a magnetic flux. In the same way electricity follows a complete closed circuit, the path of a magnetic flux is also a complete and closed circuit which leaves from the N pole, migrates through the air and reenters the magnet through the S pole through which it passes back into the magnet to come to the N pole again.
As such the magnetic field lines emanate from the N pole which is on he right to the S pole which is on the left. Hence the arrow should point in the left direction.
