Answer 1

there are following characters of magnetic lines of forces
a) they flow from the south pole to the north pole within a material abd north pole to south in air.

b) they never cross each other .

c) they all have same strength .

d) their density decrease (they spread out ) when they move from an area of higher permeability to area of lower permeability .

e) their density decreases with increasing distance from the pole.

Answer 2

Answer:

i) Two lines of force never intersect each other.

ii) They are closed and continuous curves.

iii) The direction of the magnetic field lines is from south to north.

iv) The direction of the magnetic field lines inside the magnet is from north to south
