Air Core Coil with Insulating Film Cladding

The air core coil is composed of two parts, namely the air core and coil. When we see the name, it is naturally to be understood that there is nothing in the center. Coils are wires that are wound circle by circle, and the wires are insulated from each other. When current flows through the wires, a magnetic field is generated around the coil, and the strength of the magnetic field is proportional to the strength of the current flowing through the coil and the number of turns in the coil. Similarly, within a certain magnetic field, a coil is used to cut the lines of magnetic force, the magnetic field can be converted into electrical energy. Using this principle of electromagnetic conversion, devices such as relays, motors, electric motors, wireless devices, and trumpet can be made. The wire material can be metal materials such as copper, iron, aluminum, and gold. A metal magnetic device can be inserted into the center of the coil to enhance the magnetic field generated by its conduction current. When there is only a plastic skeleton or no skeleton in the center of the coil, a air core coil is formed. Air core coils are widely used and are designed to be circular, square, elliptical, and various irregular shapes to meet various needs.
