As simple mains transformer = 2 coupled inductors...
A more complex smps mains supply uses a high frequency transformer = also 2 coupled inductors...
In every motor --> inductors
In relays, speakers, generators, ...
A lot in power electronics.
Just a piece of cable connecting the mains to your television = inductor...
I think people doesn't like inductors because they don't understand so well as a capacitor, which just hold a voltage applied to it. In fact an inductor just holds the current you have put in (put in a current somehow, short the inductor, and the current will flow forever (theoretically))
