Question

Assertion: Magnetic lines of force never intersect.

Reason: The direction of magnetic lines of force in a magnetic field is from north to south.

• A. Assertion and reason are correct and reason is the correct explanation.
• B. Assertion is correct and reason is wrong
• C. Assertion and reason are correct but reason is not the correct explanation for the assertion
• D. Assertion and reason are wrong.

Answer 1

The correct option is C

Assertion and reason are correct but reason is not the correct explanation for the assertion

Properties of lines force are:

1. Two lines of force never intersect each other.
2. Magnetic lines of force start at the north pole and end at the south pole outside the magnet. Inside the magnet, the lines of force move from the south pole to the north pole.

The reason for the given assertion that "two lines of force never intersect each other" is:

1. If the two lines intersected there will be two directions for the same point which is not possible.
2. Therefore for the given question Both Assertion and Reason are true but the reason is not the correct explanation for the assertion.

Hence, the correct option is option C.
