Question

The arrow on magnetic field lines shows them flowing in which direction?

Answer 1

For direction, if we have a bar magnet marked with North pole and south pole, then the field flows out from the north and back into the bar from the south. But if no such help is present, then we simply use an arrow mark along the line to show the direction of the field (along the line in the direction of the arrow).
