Familiar with the electrician industry line management personnel on the inductor coil this part is certainly not strange, in our daily work in the mechanical industry, the inductor coil is a very wide range of electronic parts. So you know the specific role of the inductor coil are those? How to play a better role? Next, I will take you to understand it!
The basic concept of inductive coil
Coil is a circle of wire by a circle on the insulating tube, the wires are insulated from each other, and the insulating tube can be hollow, can also contain an iron core or magnetic powder core. The inductance of a coil is denoted by L, and is measured in Henrys (H), milli-Henrys (mH), and micro-Henrys (μH), with 1H = 10^3mH = 10^6μH.
Principle of operation of inductive coils
An inductive coil is a device that works by utilizing the principle of electromagnetic induction. When a current flows through a wire, a certain electromagnetic field is generated around this wire, and this electromagnetic field of the wire itself inducts the wires that are within the range of this electromagnetic field. Generate an electromagnetic field on the role of the wire itself, called “self-induced”, that is, the wire itself produces a change in the current produces a change in the magnetic field, the magnetic field further affects the current in the wire; in the range of the electromagnetic field on the role of other wires, called “mutual inductance “.
Inductance of the electrical characteristics of the coil and capacitors on the contrary, “through the low-frequency, high-frequency resistance”. High-frequency signals through the inductive coil will encounter a great deal of resistance, it is difficult to pass; and for low-frequency signals through it when the resistance is relatively small, that is, low-frequency signals can be easier to pass it. The resistance of an inductive coil to direct current is almost zero.
Resistance, capacitance, and inductance all present some resistance to the flow of electrical signals in a circuit, which we call “impedance”. The impedance presented by an inductive coil to a current signal utilizes the self-inductance of the coil. Inductive coils are sometimes referred to simply as “inductors” or “coils” and are denoted by the letter “L”. When winding an inductive coil, the number of turns of the coil is generally referred to as the “number of turns” of the coil.
