Induction coil
An induction coil is an electrical transformer used to produce high-voltage pulses from a low-voltage direct current (DC) supply. It consists of two coils of wire—primary and secondary—wound around a common iron core. When current passes through the primary coil, it creates a magnetic field that induces a high voltage in the secondary coil. Induction coils are essential components in ignition systems, spark generation, and scientific experiments requiring high-voltage pulses.
Commonly used in automotive ignition systems, laboratory equipment, and electromagnetic experiments, induction coils enable the conversion of low voltage to the high voltage necessary to generate sparks or initiate other electrical discharges.
