Answer / abhishek kesarwani

Akshay see the conductor always rotates and its position
varies continuously. we know very well if it stops at any
point then emf will not be produced, so if you simply pay
attention on the square wave then you can find that the
angle is stationary and only amplitude increases and after
the maximum amplitude the amplitude stops varying and angle
increases and the same funda goes on. And the same shall be
aplicable for any other wave forms.
Unlike if you see the sine wave at every point its amplitude
and angle changes like the position of conductor changes.
Hence the output we get is sinusoidal...

Hope it is clear now....

Answer / kunal

If the magnetic feild is varying sinusoidally then emf induced ,which is diffential of flux will definately be sinusoidal

Answer / akshaykumar

Because due to
sinusoidal law.....

Answer / @vi

Because varying magnetic field is produced using
alternating current which is sinusoidal in nature. So when
the conductor moves through these sinusoidal magnetic flux,
sinusoidal voltage induces in it.

what is the need of representing AC power in sinusoidal waveform? why not in square or rectangular etc...
