A simple generator has a 655 loop square coil 19.7cm on a side. How fast must it turn in a .490 T field to produce a 110V peak output? give your answer in radians/second

I used V=NBAwsin(wt)

where V = 110, N=655, B=.490, A=.197*.197, w simplifies to 2*pi*f, wt simplifies to 2*pi

so plugging in, 110=655*.490*.197*.197*2*3.14*f*sin(6.28)

i get f = 12.85 rev/s * 360/57.3 = 80.76 rad/s

but this is wrong..

anyone know where i went wrong?

places i suspect are: wrong formula, and i am using the sin(6.28) incorrectly..

any hints?

thanks
