Question

What are the properties of magnetic field lines? Give its formula

Answer 1

Answer:

they are always closed loops

the lines point from north to south pole outside magnet and vice versa inside

the magnetic field lines can never cross each other

density of lines is proportional to strength of field

stronger the field the lines converge the weaker the field the lines diverge

please mark it as brainiest!!!!

Answer 2

Answer :

• Definition → Magnetic field lines are used to represent magnetic field.

★ Properties of magnetic field lines :

• They forms closed looms.
• They do not intersect with each other.
• They have streched elastic property.
• They contact laterally.
• Their direction is indicated by arrows in the line at any point.

★ Additional information :

• SI unit of magnetic fields is Tesla (T).
• Magnet field lines are created from a moving electric charge.
• Example :- Compass .
