Question

List the properties of magnetic lines of force

Answer 1

Properties of Magnetic lines of force are as follows:

(i) They flow from the south pole to the north pole within a material and north pole to south pole in air

(ii) They never cross each other

(iii) They all have the same strength

(iv) Their density decreases(mainly they spread out) when they move from an area of higher permeability to an area of lower permeability

(v) Their density decreases with increasing distance from the poles.

(vi) The expansion of lines of magnetic field accrue in lateral position and contraction in longitudinal position.
