Lines of force
Magnetic lines of force and their properties listed out very useful to 10th cbse boards

line of force definition

line along which a freely suspended north pole tends to move is called line of force

properties

1.line of force moves north to south outside the magnet

2.inside the magnet they move from south to north

3.they are closed and curved lines

4.they are crowded at poles (because are poles are relatively more stronger then middle of magnet)

5.no two lines of force will ever intersect
because if they intersect feild is in two directions
which is not possibel
(at a given point feild cant be in 2 directions simultaneously)

6.tangent at any point on line of force gives direction of magnetic feild at that point,
