Question

What are magnetic lines of force? Give four properties.
​

Answer 1

Answer:

${\huge{{{\mathfrak{\fcolorbox{pink}{r}{Answer - }}}}}}$

A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetized materials. A charge that is moving in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field

Answer 2

Magnetic lines of force are the lines that depict the magnetic force that exists in the surrounding of the magnet. ... As the distance between the poles increases, the density of magnetic lines decreases. The direction of field lines inside the magnet is from the South Pole to the North Pole.

General Properties of Magnetic Lines of Force

• They seek the path of least resistance between opposite magnetic poles. ...
• They never cross one another.
• They all have the same strength.
• Their density decreases (they spread out) when they move from an area of higher permeability to an area of lower permeability.
