question mark

sir plzz tell why cant we use circular coil instead of rectangular coil in A.C generator...as circular coil though if is taken of same length as that of rectangular coil as larger area so more magnetic field lines will cross through it and so torqu nBIA will be more resulting into more induced current....

If you are knowing the concept of Moving Coil Galvanometer, in which the geometry of the magnets is considered to be radial.
To have maximum amount of induced current, for this it need to has maximum time varying flux containing maximum area.

Good Luck !!!!
