Question

draw the magnetic field line with the four properties​

Answer 1

The properties of magnetic field lines can be summarized by these rules: The direction of the magnetic field is tangent to the field line at any point in space. A small compass will point in the direction of the field line. The strength of the field is proportional to the closeness of the lines.

Answer 2

* The magnetic field lines start from the North pole and end up in the South pole.

* The magnetic field lines are closed curves.

* Inside the magnet, they travel from South pole to North pole

* Two magnetic field lines do not interest . If they do, then it mean that at the point of incident, the compass needle would point two directions, which is impossible.
