Question

What are magnetic field lines?List the properties of magnetic
field lines.Why do two magnetic field lines never intersect each
other?

Answer 1

The lines surrounded at the attraction of two bar magnets is called magnetic fields

Properties of magnetic fields are

1. Emerge from north

2. Merge at south.

3.Never interact each other.

Magnetic field lines interact each other because if they interact then it show two different directions which is not possible..

Answer 2

The magnetic field can be defined as:

“A region around/surrounded by a moving electric charge or a magnetic material within which the force of magnetism acts.”

How does Magnetic Field occur?

If you are wondering how Magnetic fields occur. Well, it occurs whenever a charge is in motion. That being said if you apply more charge in the motion the strength of a magnetic field usually increases. Besides, Magnetism and magnetic fields are part of the electromagnetic force which is indeed one of the four prime forces of nature.
