how does a fan work
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.
