An induction coil serves several important functions:
Energy Storage: It stores energy as a magnetic field in its core. When a fluctuating current flows through the coil, it converts electric current energy into magnetic field energy, and vice versa.
Electromotive Force (EMF) Generation: The induction coil develops an electromotive force (EMF) in a direction that reduces fluctuations. This property is useful for stabilizing electrical circuits and minimizing voltage variations.
Energy Conversion: It efficiently converts electrical energy into magnetic energy and vice versa. This capability is essential for various applications, including transformers and electrical circuits.
High Voltage Generation: Induction coils were historically used to provide high voltage for electrical discharges in gases at low pressure. They played a crucial role in the discovery of cathode rays and X-rays in the early 20th century.
Tesla Coil: A specialized type of induction coil, known as the Tesla coil, generates high voltages at high frequencies. It has applications in wireless power transmission, radio communication, and scientific experiments.
