i have cos(wt) not sin(wt) !

but i find this expression : E = N L r w B cos(wt) ====> must find sin (wt) instead of cos (wt)

which force you talk about ? the rectangle is fixed and the flow varies, I think to use the flow of magnetic induction, I think to use Faraday's relationship e = - dΦ / dt (the derivative currency flows on derivative temp). in using Φ=∫∫ B.dS

hi, How can I demonstrate the relationship of the electromotive force of a motor AC thank you
