I hope it's helpfull

Explanation :

☆Answer 1}

: Properties of magnetic lines of force are:

Properties of magnetic lines of force are:The imaginary lines which represent the direction of magnetic field, are known as magnetic lines of force. Magnetic lines of force are closed curves. Outside the magnet their direction is from north pole to south pole and inside the magnet these are from south to north pole.They neither have origin nor end. These lines do not intersect, because if they do so then it would mean two value of magnetic field at a single point, which is not possible. At the poles of the magnet the magnetic field is stronger because the lines of force there are crowded together and away from the poles the magnetic field is weak.

☆Answer 2}

:the north and south poles cannot be separated. It is a distinct difference from electric field lines, which begin and end on the positive and negative charges. If magnetic monopoles existed, then magnetic field lines would begin and end on them.

☆Answer 3.}

:

The magnetic field lines never intersect each other because if two or more lines intersect each other than it means that at that point of intersection, the magnetic field has two directions at the same point. This is not possible for a magnetic field to point in more than one direction at the same point.
