What is the purpose of the inductance coil and how to distinguish it

What is the purpose of the inductance coil and how to distinguish it

The reason why the inductance works is that it produces a changing magnetic field when passing an unstable current, and this magnetic field will in turn affect the current. So, in this case, any conductor, as long as it passes an unstable current, will produce The changing magnetic field will in turn affect the current, so any conductor will have self-inductance.

Introduction to the inductance stability of the inductance coil

Inductance refers to the intensity of the current that the coil can induce when it moves in a magnetic field, and the unit is "Henry" (H). Also refers to components made using this property. Inductance is the electromagnetic induction characteristic of the inductance element in the circuit! (Including self-inductance and mutual inductance), the coil is an inductive element. Broadly speaking, inductance exists in the circuit, and any component is not just a coil to have inductance! In a circuit with a sufficiently high frequency, any component circuit has an inductive effect. Correctly speaking, a coil is an inductive element, and the main element of an inductance is a coil.

How to judge the quality of the integrated inductor

Good or bad judgment: The reading of the chip inductor at this time should be zero. If the multimeter reading is too large or infinite, it means that the inductor is damaged.

Does the winding direction of high-power inductors affect the inductance?

High-power inductors store energy in a magnetic field to perform their functions. However, inductance is not only affected by the electromagnetic energy generated by itself, but also by external magnetic flux. The inductance value of the guaranteed component refers to the value under the condition of no external magnetic flux. Therefore, when the high-current magnetic bar inductor is packaged in the presence of external magnetic flux, it may not be able to perform its due function. As a typical example, multiple inductors will be packaged very closely.
