Question

What are magnetic field lines how is direction of magnetic field at a loint determined mention any two important properties of magnetic field lines?

Answer 1

magnetic field lines are continuous closed curves in a magnetic field such that the tangent drawn at any point in the curve gived the direction of magnetic field at that point

the tangent drawn at any point of the curve field line gives the direction of magnetic field at that point

thats the defination if u want me to sxplain the whole thing to u pls mark as brainliest follow me and comment me on this answer so i know that u need the explanation

properties of magnetic field lines are
1.they act as streatched rubber or elastic bands
2.they are closed continuous curves
3.they never intersect each other
4.tangent drawn at any point of the field line will give you the direction of magnetic field at that point

hope it helps pls mark as brainliest and comment for more explanations

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.
