Question

what does magnetic field line means​

Answer 1

Answer:

The magnetic field is an abstract entity that describes the influence of magnetic forces in a region. 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. Because monopoles are not found to exist in nature, we also discuss alternate means to describe the field lines in the sections below. One useful analogy is the close connection between magnetic monopoles and electric charges.

Answer 2

Answer:

magnetic field of lines are imaginary lines of force emmited by North Pole and entering south pole outside the magnet and inside the magnet from South to North Pole they never intersect each other
