Answer 1

Important properties of magnetic field lines due to a bar magnet:

1. Field lines form a close loop
2. Field lines do not intersect
3. Degree of the closeness of lines represents the relative strength of the field in regions
4. The direction of a magnetic field at a point is along the tangent to a line at that point
