AC Generator Concepts and Functions

The video tutorial guides viewers through drawing an AC generator. It starts with creating two rectangular boxes representing the North and South Poles of a magnet. A parallelogram is drawn between these boxes to represent the coil, with magnetic flux arrows added. Slip rings and carbon brushes are illustrated next, followed by springs and horizontal lines representing alternating EMF. The tutorial concludes with the addition of an axle and a circular arrow indicating coil rotation, completing the AC generator diagram.

What do the two rectangular boxes in the AC generator diagram represent?
