In the internal structure of the computer power supply, we often see some winding coil, most consumers will know that this is the inductance. But how does the inductor work? I believe many consumers are not very clear. In fact, the inductor is a closed loop in the property, when the closed-loop current changes, the inductor will produce electromotive force to resist the current changes, this is also called self-inductance. While the inductance of the induction effect will make another inductor to produce electromotive force, so the inductance called mutual inductance.
Inductance of this feature in real life is still very wide range of applications, we are the most common mode choke coil . This inside the main power supply is used to filter out interference, making the circuit current does not change much, so that the power supply to run more stable. So how does the inductor work? Next, we will give you a brief introduction.
In fact, the inductor is made of conductive material coiled core, we are common is the copper wire wound on the core. Especially in the computer power supply, this inductance is very common. Here's a look, what we call the inductance of it.
Inductance is divided into self-inductance and mutual inductance
According to the law of electromagnetic induction, we can know that when there is current in the differential choke coil the coil will have a magnetic field around. When the current changes, the surrounding magnetic field should also have a corresponding change in the magnetic field can change the coil itself to produce induced electromotive force, the electromotive force will be against the current changes, this is called self-inductance. When two inductors close to each other, the magnetic field of an inductor coil changes will affect the other inductance coil, and this is called mutual inductance.
Finally, we come to the conclusion that the inductance is actually a conductive material wound coil, and the coil is a characteristic of electromagnetic induction, so the coil is what we call inductance.
