Question

Give any three properties of the magnetic lines of force.​

Answer 1

Answer:

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.

Answer 2

• Each line is a closed and continues curve.
• They will never intersect each other.
• They are crowded near the poles where the magnetic field is strong.
