Question 2
List the properties of magnetic lines of force.
Answer 2
Properties of magnetic lines of force/magnetic field lines are as below
Question 3
Why don’t two magnetic lines of force intersect each other?
Answer 3
The law of Physics says that, no two field-lines are found to cross each other. If they did, it would mean that at the point of intersection, the compass needle would point towards two directions, which is not possible.
