Magnetic Flux: Practice Problem & Solution

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of Magnetic Flux. Understanding the underlying formula is key to arriving at the correct answer below:

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.
