Question

what are magnetic field lines justify the following statements 1)two magnetic field lines never intersect each other .
2) magnetic field lines are closed curves .


I want easy answer

Answer 1

Electric current produces a magnetic field. This magnetic field can be visualized as a pattern of circular field lines surrounding a wire. One way to explore the direction of a magnetic field is with a compass, as shown by a long straight current-carrying wire in. Hall probes can determine the magnitude of the field. Another version of the right hand rule emerges from this exploration and is valid for any current segment—point the thumb in the direction of the current, and the fingers curl in the
of the magnetic field loops created by it..

Magnetic Field Lines :-The path traced by a north magnetic pole free to move under the influence of a magnetic field is called magnetic field lines.

1) No two field-lines are found to cross each other. If they did, it would mean that at the point of intersection, the compass needle would point towards two directions, which is not posdible.

2) Inside the magnet, however the direction of magnetic field lines is from the South pole to the North pole of the magnet. Thus, the magnetic field lines are Closed Curves.
