It is not hard to set up a home theater. Manufacturers of all types of electronic equipment have made it extremely easy over the past decade or so.
what is an inductor used for
Since we know that inductance of an inductor depends on the length of inductor by the formula L=muAN*N/l, where l is the length of inductor. So by varying the length of inductor we say that inductance of inductor varies.

Yes it does as it is an Inductor and an Inductor needs to build up a magnetic field. It is called INRUSH current.
Ten YEARS make a decade. A decade is larger than a yeaR

A decade is made up of ten years. It takes ten years to make one decade. A year is one tenth of a decade.
Yes, it possible to heat a coil using dc power supply. An inductor resists a change in current, proportional to voltage and inversely proportional to inductance. The equation of an inductor is di/dt = v/L An ideal inductor, if connected to an ideal DC supply, with ideal conductors, would ramp up current in a linear fashion without limit, eventually reaching infinity amperes after infinite time. Since no inductor is ideal, nor is any DC supply, nor is any conductor, the current would reach a maximum based on the capacity of the DC supply and the DC resistance of the inductor and conductors. Since the DC resistance of the inductor is also not zero, this means, by Ohm's law, that the inductor must dissipate some power. That will cause the inductor to heat up.
