Hi,

So, I am learning about induced emf. I am having a hard time grasping the idea that we are interested in the angle between the normal to the plane of the coil and the magnetic field. In the standard illustration I actually understand it, but the following question confuses me.

We are dealing with the flux enclosed, so, shouldn't we want to find the cosine of the angle in the question attached as a picture?

Thanks!
