Correct answer: B

NEET 2022 Phase 1 Physics - Electromagnetic Induction Question 6 English Explanation

Magnetic flux ($\phi$B) = $\overrightarrow B $ . $\overrightarrow A $

$\overrightarrow B $ and $\overrightarrow A $ are in same direction, therefore

$\phi$B = B . A = 0.5 $\times$ 12

= 0.5 Wb
