What is induction coil?

An induction coil is a type of electrical transformer that is used to increase the voltage of a low voltage, high current source to create a high voltage, low current output. It consists of two coils of wire, known as the primary and secondary coils, wrapped around a magnetic core.

When an alternating current is passed through the primary coil, it creates a fluctuating magnetic field that induces a current in the secondary coil. The ratio of the number of turns in the primary coil to the number of turns in the secondary coil determines the voltage ratio between the input and output.

Induction coils are commonly used in devices such as ignition coils in internal combustion engines, Tesla coils for high voltage experiments, and induction heating equipment. They are also used in various applications in electronics, telecommunications, and power distribution.

Overall, induction coils are versatile devices that play a key role in transforming and manipulating electrical energy in various applications.
