• They form complete loops

• They never cross

• All of these

• None of these

Are the magnetic field lines in the picture correct?

• Yes, because they point from north to south.

• 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).
