Recall / Warm-Up

Magnetic flux $\Phi_B$ is defined as $\Phi_B = BA\cos\theta$ . What does $\theta$ represent in this formula?

The angle between the magnetic field and the loop's edge.

The angle between the magnetic field $B$ and the normal to the loop's surface.

The angle between the induced EMF and the current.

The angle at which the magnet approaches the loop.
