What is the self-prime coil? Principle in the circuit

In the circuit self-inductance coil principle Great resistance corresponding to the resistance. Large inductance because the larger self inductance of the coil when the circuit is turned on, the current changes very fast, due to. The greater the ability to prevent the self inductance of the coil current rises, the equivalent of an open circuit when the circuit is first turned on. What is the self-inductance coil Inductance coil is a coil, it must not be understood as a small spring. When a coil current change, current change generated by the flux coil loop itself also changes, induced electromotive force of the coil itself. Its self-sensing is a physical quantity of the characterization of the self-inductance. The self-sensing is also called self-sensing or inductance. It is used to use Henry (H) to do units, and it is called millions of millions (MH One million parts are called microencorn (μH), and the microencier is called Nahant (NH). In fact, the inductance popular thing generally refers to the solenoid, when he was through current changes, will produce some general of wires different effects, so give it another name inductance. The inductor acts only on the non-constant current, the voltage across it is characterized by his proportional to the instantaneous rate of current change (derivative), the scale factor is its "self." The reason is that the magnetic field inductance works it produces a change in the non-steady current through, and this in turn will affect the current magnetic field, so, so to say, any conductor, as long as it is through non-steady current, will produce varying magnetic field, in turn will affect the current, so any conductor will have a self-inductance phenomenon.
