Transformer is to transform ac voltage, current and impedance of the device, when the primary zhongtong have alternating current coil, iron core (or core) to produce ac magnetic flux, induced in the secondary coil voltage (or current). Transformer is composed of iron core (or core) and the coil, coil, there are two or more than two windings, which connect power winding is called primary coil and the rest of the winding is called secondary coil. In the generator, whether it's movement through the magnetic field or magnetic field coil through fixed coil, all can induction electric potential in the coil, the two cases, the value of the magnetic flux are unchanged, but the fellowship with coil chain there is a change in the number of magnetic flux, this is the principle of mutual induction. The transformer is one kind of use of electromagnetic should be mutual inductance, transform voltage, current and impedance of the device.
