Dear Student

electric fan works on the principle of electromagnetic induction.there are two parts of this one is stator and other is rotar.induction machine are ac machines.stator is given single phase ac voltage which produces sinuosoidal flux and emf is induced in the rotar and acc to lenz law current flows in a direction so as to oppose the cause that has produced effect in this case it rotates in similar direction as that of sinuosoidal field..and rotar rotates so blades attached to it also rotates and we get cool air

 

All the best.

the centre of mass of fan is buldged downwards so as to make it rotate faster .

the moter rotates the fan n the blades of fan are tilted at an angle such thut they can pressurise air above fan n between ceiling

so the air comes down with speed
