Question
If a loop of area 50 cm² is placed parallel to a 0.5-T magnetic field (so the normal is perpendicular to B), what is the flux?
Correct Answer
Option C is the correct answer.
Detailed Explanation
When the loop is parallel to the field, the angle between the normal and B is 90°, cos 90° = 0, so Φ = 0 Wb. No flux penetrates the loop.
Hint
Parallel to field = zero flux.
