NEET Physics Question - Electromagnetic Induction

Assertion (A): Magnetic flux is a vector quantity.

Reason (R): Value of magnetic flux cannot be negative.

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

Both A & R are true but the (R) is not the correct explanation of the (A)

(A) is true but (R) is false

Both (A) and (R) are false

Solution:

Magnetic flux \(\phi = \vec{B} \cdot \vec{A}\) is a scalar quantity (A is false). Also, \(\phi = BA cos\theta\) can be negative when \(cos\theta\) is negative, indicating direction relative to area normal (R is false). Both are false.
