Question

write any four properties of a magnetic lines of force

Answer 1

1) They start from north pole and end at south from outside.
2) No two magnetic field lines intersect each other.
3) The direction of the magnetic field can be found by drawing a tangent.
4) The place where the magnetic field lines are closer have high magnetic power n vice versa.



Hope it helps!!!

Answer 2

1) Magnetic field line is an imaginary curve, the tangent to which at any point gives direction of Magnetic field B at that point
2) The magnetic field lines of a magnet form close continuous loops.
3) Outside the body v of magnet, the direction of magnetic field lines are from north pole to South Pole
Magnetic line of force come out and go into a magnetic material at any angle.
