What is an induction coil?
Induction coil is a type of electric transformer that uses DC power with low voltage DC power to produce. The coil consists of two coils composed of insulating copper wire wound around common iron. The first coil is small, usually made up of tens or hundreds of rough wire revolutions. This is known as the primary winding. The second coil, known as the secondary winding, consists of thousands of revolutions.
The coil works by sending a small electrical current through the primary coil. This creates a magnetic field. Because both primary and secondary windings, omothane around the common iron of the nucleus, the primary winding is associated with the secondary winding. When the voltage entering the primary at once is interrupted or stopped at the same time, the magnetic field collapses quickly.
The sudden magnetic field collapse creates a high voltage pulse to develop across terminals associated with secondary winding process known as Electromagnetic induction. Given that secondsAry coil has thousands of wire revolutions, the created pulse is in thousands of volts. In most cases, when a pulse is created in a secondary coil, it creates a spark or a jump between terminals. Therefore, an induction coil is often referred to as a "spark coil".
In order for the induction coil to work, the electric current must be fed to the primary coil continuously. The device that causes interruption is known as a brewer. The interruption that connects and breaks the current with the primary winding is made of vibrating mechanical contact.
When a magnetic field is created in the primary winding, this field attracts or pulls an iron anchor that is connected to the spring. This pulling of the Iron Armature disrupts a few contacts that connect to the energy source. Once the energy source is broken, the magnetic field collapses, resulting in closing contacts in the spring. When the contacts are closed, the cycle beginsagain.
Induction coils are used quite often in television files and other electronic devices where low voltage to high voltage needs to be converted. The car ignition system uses an induction coil to convert the battery energy. Induction heating is the use of an induction coil to provide located, controlled thermal objects located inside the coil.
