Asked by Alveera
Q:A 50 turns coil in a generator has an area 500cm(square)rotates in magnetic field with B=1.76 w/m(square), how fast must the coil be rotated in order to generate a maximum voltage of 220 volt?

Flux is 500cm^2 (change that to m^2)times B times winding turns. deltatime is the reciprocal of frequency.
emf=- d flux/dt= -Area*B*n/time=-area*B*rate*n
solve for rate.
