Hi everyone,(adsbygoogle = window.adsbygoogle || []).push({});

Apologise for so many questions within a short period of time. I'm in the midst of my holidays and I can't clarify my doubts in school.

For a particular A.C generator, it has a large rotating rectanglar coil rotating at 50 rev per second in a B field strength of 0.29T. It has 38 turns each 2m long and 1.2m wide.

How do I find the flux cut by one turn of the coil after the coil has rotated 1 degrees from the position parallel to the B field lines of force, which position generates the largest EMF?

I found that the time required for it rotate 1 degrees is 5.56 X 10^-5 s. I know the flux linkage is BAcosx. How do I find the area that is being cut? I couldn't find the surface area of the coil without the radius?

Thanks a lot people.
