I am studying about to do a student project about improving power factor which is less than 1 because of inductive loads. How it work I know but what I want to know is that what to use as inductive load. Should I use two terminal components called inductors which are available pretty easily in markets? If yes then please can anyone tell which different standard values of inductors should be used to decrease power factor to different values?? I want to use at least 5 inductive loads. so how to calculate values of inductors on a 220 v mains supply that will give noticeable reduction in power factor. any formula?

my friend suggested me to use a multiple winding transformer as a load so each winding will act as an inductive load. is it possible. if yes. then how i am gonna get the inductive value for the winding? Please please help
