Why the transformer can change the voltage?

Why the transformer can change the voltage?

Basic theory:

One simple and single-phase transformer is made of two electric conductor.When one of them has some non-mensurable current(such as alternating current or impulse style DC)to pass,and then it can bring magnetic field.According to the theory of the electromagnetic mutual inductance,the up-and-down magnetic field can make another electric conductor bring the electric potential difference.Provided that the second electric conductor is one of piece on the closed circuit,the closed circuit should bring the current,so that the electric power can be transmitted.

During the all-purpose transformer,the related electric conductor is made from(a great number of copper)winding composed with the electric wire,because the magnetic field is brought by winding should be stronger than a piece of straightforward and electric wire.
