The role of the inductance in the circuit

The role of the inductance in the circuit?

Electric magnetism, magnetic raw power, the two complement each other, and always with your display.
When a wire has a constant current flows, there is always a constant magnetic field around the wire stirred. When these wires are bent into a spiral coil, the application of the law of electromagnetic induction, we can conclude that spiral coil in a magnetic field. This spiral coil is placed on a current loop, when this circuit DC changes (such as from small to large may be contrary), the magnetic field in the inductor should be changed, and a magnetic field change will bring about changes in the new current ", by the law of electromagnetic induction, this" new current "certain contrast and the original direction of the DC, thereby constituting a certain resistance to change within a short time on a DC. Just once the change is completed, the current firm up the magnetic field does not change, we are no longer any obstacles.
