Magnetic field lines do not cross each other because, at the point of intersection, the compass needle would have to point towards two directions simultaneously, which is not possible.

The relative strength of the magnetic field is indicated by the degree of closeness of the field lines. A stronger magnetic field is associated with crowded field lines.

Inside a magnet, the direction of magnetic field lines is from its south pole to its north pole, forming closed curves.

The direction of the magnetic field is determined by the direction in which a north pole of a compass needle moves inside it. Conventionally, it is established that magnetic field lines emerge from the north pole and merge at the ...

Yes, magnetic field lines around a bar magnet can be obtained by drawing them. It is possible to manually represent the magnetic field lines through observation and illustration.
