Assertion (A): Magnetic field lines never intersect.
Reason (R): At a particular point magnetic field has only one direction.
All Field lines follow their separate path to reach from North Pole to the South Pole.
Two magnetic field lines do not intersect each other because if there was point of intersection,
The compass needle would point towards 2 directions.
Which means that the magnetic field has two different directions, which is not possible.
- Assertion is true.
- Reason is true.
- Reason is the correct explanation for Assertion.
So, the correct answer is (a)
