Question

draw the magnetic field lines outside and inside bar magnet. if magnet field lines are close then what does it shows? ​

Answer 1

$\huge\mathfrak{Answer:-}$

⭕ When we sprinkle iron fillings near a bar magnet or regions around a bar magnet, the iron fillings experience a force which compel them to come in a pattern, hence the iron fillings allign themselves in a pattern and are known as Magnetic Field Lines.

⭕ The strength of magnetic field is determined by the degree of closeness of field lines.✔️✔️

⭕ The region where magnetic field lines are closest , the magnetic field is strongest.

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.
