Magnetic Flux Practice Test

Flux varies with $\cos\theta$, using $\theta$ between $\vec B$ and the loop’s area normal.

Flux is unchanged by orientation because $B$ passes through the loop regardless of angle.

Flux is greatest when the loop plane is parallel to $\vec B$, because more field enters sideways.

Flux depends only on $A$, so rotating the loop cannot change $\Phi$.
