I am currently designing a three phase permanent magnet axial flux generator, but have a question regarding the voltage induced in the copper coils. Faraday's law defines this voltage as the number of turns in the coil, times the change in flux (external magnetic field times area of coil) over the change in time. As i tried to illustrate in this sketch:
However in my generator (and to my knowledge, in most others), the interaction between the coils and the flux is a bit different. I am not sure how to define the area in my case, as the source of flux is not passing through the entire coil, but instead parallel to it. The sketch below describes the basic principle of my generator:
I just assumed that the area is that of the coil section affected by the magnet, instead of the total coil area, as shown here:
My question is, if the above assumption is correct?
Any help is greatly appreciated
