Answer:
C. South pole on the left end and north pole on the right end
Step-by-step explanation:
From the figure, we can conclude that the poles of the magnet are on either sides of the magnet
Therefore, options 1 and 2 are excluded
It is a convention that the magnetic field lines move out of the north pole of a magnet and into the south pole of the magnet
From the figure, we can see that the magnetic field lines are moving out from the right end and into the left end
This means that the north pole is at the right end and that the south pole is at the left one
Hope this helps :)
