Detailed explanation-1: -Magnetic field lines never cross.

Detailed explanation-2: -No, two magnetic field lines do not intersect each other. If they would intersect, there would be two directions of the field at the specific point which is not possible.

Detailed explanation-3: -The arrows represent invisible lines of force, known as magnetic field lines. They indicate the direction a compass arrow lies – pointing north–south.

Detailed explanation-4: -the lines have arrowheads to show the direction of the force exerted by a magnetic north pole. the arrowheads point from the north pole of the magnet to its south pole.
