Question

what are megnetic field lines? what are its properties and characteristics? ​

Answer 1

Answer:

The lines that show magnetic field is strong of weak are called magnetic field lines.

Explanation:

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. It is exactly proportional to the number of lines per unit area perpendicular to the lines (called the areal density).

Magnetic field lines can never cross, meaning that the field is unique at any point in space.

Magnetic field lines are continuous, forming closed loops without beginning or end. They go from the north pole to the south pole.
