Magnetic lines of force due to a bar magnet do not intersect because

A

a point always has a single net magnetic field

B

the lines have similar charges and so repel each other

C

the lines always diverge from a single point

D

None of the above

Text Solution

Verified by Experts

The correct Answer is:
D
Magnetic lines of force due to a bar magnet do not intersect becaues if they intersect then it means, there are two directions of magnetic field intensity which is impossible.
