Are the magnetic field lines in the picture correct?
Yes, because they point from north to south.
No, because they point from north to south (they're supposed to go the other way).
Yes, because the North pole is on the left in all pictures.
No, because the North pole is on the left in all pictures (it's supposed to be on the right).

Attracting
Repelling
Attracting and Repelling
Doing nothing
