is there any change in the current when the regulator of the fan is rotated...

from the electric scouce to the motor electric current (flow of electrons in one direction),
in the motor
electric current interfears with magnetic flux thus pushing the rotator away since it is fixed to one point it rotates trying to move away(like the way like poles repell) thus the energy changes from electric to mechanical through elecromagnetic.
then when the fan rotates (notice that the propellers are curved so as to scoop air molecues pushing them forward creating a kind of vaccum that is imediatley filled then the same procces is repeated creating wind not concention )
if it were convention it would require change of temperature and this only applies the principle of pushing air (like a pedal pushing water only that it is air the propellers are pushing)

Working Principle Of Electric Fan

I think the principle behind the fan is similar to that of the dynamo. It uses the fleming's left hand rule. Im not sure so dont rely on my answer.

works on the principle of barlows wheel , an effect due to both magnetic and electric field simultaneously

Charu, another piece of homework for you....check this site for details how a electric motor works.
