Working of A DC Generator

Let us consider a single turn rectangular coil which is rotating in a anti-clockwise direction with angular velocity (w) radians per second in a uniform magnetic field of flux density B tesla ,
when the coil is rotated in a uniform magnetic field with uniform angular velocity an emf is induced in its coil sides and its magnitude depends upon B , the effective length of the coil 'l' number of turns in the coil 'N' , velocity of the coil side perpendicular to the field Vp :

hence the formula for the EMF becomes : E= 2NBlVp Volts

This is the generated emf .
