Question

Gives the properties of magnetic lines of forces (any four)

Answer 1

The properties are:

They seek the path of least resistance between opposite magnetic poles.

In a single bar magnet, they attempt to form closed loops from pole to pole.

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.

Their density decreases with increasing distance from the poles.

They are considered to have direction as if flowing, though no actual movement occurs.

They flow from the south pole to the north pole within a material and north pole to south pole in air.
