Question

what is magnetic fields lines ​

Answer 1

Magnetic field lines are a visual tool used to represent magnetic fields. They describe the direction of the magnetic force on a north monopole at any given position. The density of the lines indicates the magnitude of the field. Taking an instance, the magnetic field is stronger and crowded near the poles of a magnet.

The path along which north pole moves in a magnetic field is called magnetic lines of force or magnetic field line. They show the direction and strength of magnetic field. If magnetic field lines are very close to each other in a particular region,then the strength of magnetic field in that region,is very large.
