What is an electric coil and how does it works
In this tutorial, we will learn about the concept of a coil. The electric coil is one of the most used electronic parts, as it is found in most electronic and electrical devices, and the reason is due to its effective role in electronic circuits. What is the definition of a coil? And what is its role in electrical circuits? And what are its most important uses in the field of electronics and electricity?
Definition of an electric coil :

| What is coil electric |
The electric coil is a wire composed of copper material and it is wrapped in the form of circles with a certain number of turns on a template that is often made of plastic, and these coils are what control the value of the electric coil.
Electric coil measurement unit :
The unit of measurement for the electric coil is the Henry H, which is called the coefficient of self-induction and is symbolized by the letter L.

What is the function of an electric coil and how does it work :
The main function of the electric coil is to generate a magnetic field inside the solenoid when an electric current is passed through it. Thus, the electric coils do not allow a sudden change in the electric current.
Characteristics of the electric coils :
The electric coil is distinguished by its conversion of the electric current into a magnetic field when an electric current passes through it, and it is widely used in most electrical appliances such as electric heaters, refrigerators, radios, televisions, and even mobile phones and computers.

| Check coil electric |
To check whether the electric coil is damaged or not, we adjust the digital multimeter to the beep, and connect the ends of the coil to the device’s probes. If it makes a sound, it is good, but if it does not make a sound, then it is damaged and must be replaced.
Uses of electric coil :
The electric coil is used in many devices and electrical elements, and these are the most important uses of the electric coil:
It is used in radios and televisions, i.e. household appliances in general.
It is also used in some electronic components and elements such as relays and electrical transformers.
In general, the electric coil is indispensable, as it is found in almost all electrical appliances, due to its important role. Finally, this was a comprehensive article about the electric coil. I hope the explanation is clear to you.
