Flux through a coil is zero when its plane is placed how relative to the field?
APerpendicular to field
BParallel to field
CAt 45 degrees to field
DAt 30 degrees to field
Answer & Solution
Correct answer: B. Parallel to field
With the plane parallel to the field, the area vector is perpendicular to B, so cos 90 degrees = 0 and the flux vanishes.
