Question

Assertion (A) : Magnetic field lines cannot start from a point nor end at a point. 

Reason (R) : The line integral of magnetic field induction over a closed path is not zero.

(a) Both A and R are true and R is the correct explanation of A 

(b) Both A and R are true but R is NOT the correct explanation of A 

(c) A is true but R is false 

(d) A is false and R is also false

Answer 1

Option : (C) 

The magnetic lines of force form a closed path, hence the line integral of \(\vec B\) over the closed path is zero. 

Thus, 

Assertion is true and Reason is false.
