What are

magnetic field line ?
Mention the important properties of
magnetic field line?
​

Answer 1

MAGNETIC FIELD LINE DEFINITION:-

A 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.

THE IMPORTANT PROPERTIES OF MAGNETIC FIELD LINE ARE:

1. emerging from the north pole of the magnet to its south pole.
2. these lines are curved and continuous.
3. the magnetic field lines are parallel to each other that is they never intersect each other.
4. the number of magnetic field lines per unit area or magnetic flux is more at the poles that is the reason why the magnetic field strength strength is more at poles.

Answer 2

Question⤵️

what are magnetic field line ?

Answer⤵️

Magnetic field lines are imaginary visual tool used to represent magnetic fields. They describe the direction of the magnetic force on a north monopole at any given position.

some important properties of magnetic field lines :-

• magnetic field line never intersect each other .
• magnetic field lines are continuous loops
• The density of the field lines indicates the strength of the field
• Magnetic field lines always emerge or start from the north pole and terminate at the south pole.

That's all

Thank you for asking !
