A flat circular loop of radius 0.10 m is rotating in a uniform $\vec { B }$ field of 0.20 T.Find the magnetic flux through the loop when the plane of the loop and the $\vec { B }$ field vector are parallel. A)0 T ∙ m² B)3.1 × 10^-3T ∙ m² C)5.5 × 10^-3 T ∙ m² D)6.3 × 10^-3 T ∙ m²

Question

Quizplus · Accepted Answer

When the plane of the loop and the magnetic field vector are parallel, the magnetic flux through the loop is zero because the angle between the magnetic field and the normal to the plane of the loop is 90 degrees, leading to a cosine factor of cos(90°) = 0 in the flux calculation.
