Question

List the properties of magnetic field lines​?Give any three points

Answer 1

Answer:

1.A magnetic field lines is an imaginary curve along which a free unit north pole tends to move.

2.Magnetic field lines always starts from north pole and end on south pole

3.The tangent to the magnetic field lines at any point gives the direction of magnetic field at that point.

4.Two magnetic field lines never intersect each other.

5.It is vector quantity.

6.They always form closed loops.

7.Magnetic field lines passing through unit area around a point w.r.t. the strength of the magnetic field at that point is called Magnetic flux density

or

1.Magnetic field lines are representation of magnetic field.

2.Magnetic field lines forms closed loops.

3.They contact laterally.

4.They behave like stretched elastic rubber strings.

5.Magnetic fields lines always form closed loops.

6.Magnetic field lines do not intersect each other.

7.More the number of magnetic field lines, more strong in the magnetic field.

Answer 2

${\bold{\blue{\underline{\red{A}\pink{ns}\green{we}\purple{r:-}}}}}$

The properties of magnetic field lines are :-

➊ The magnetic field lines originate from the north pole of a magnet and end at its south pole.

➋ The magnetic field lines do not intersect or cross one another.

➌ The magnetic field lines come closer to one another near the poles of a magnet but they are widely separated at other places.

➝ magnet :- A magnet is an object which attracts piece of iron,steel,nickel and cobalt.

Related to magnetic field lines :-

➝ The magnetic field lines are the lines drawn in a magnetic field along which a north magnetic pole would move.

➝ The magnetic field lines are also known as magnetic lines of force.

➝ The direction of magnetic field lines at any point gives the direction of magnetic force on a north pole placed at that point.
