Induction Coil
Induction Coil is an electrical device used to generate high-voltage pulses from a low-voltage direct current (DC) supply. It typically consists of two coils of insulated wire (primary and secondary) wound around a shared iron core. When current is interrupted in the primary coil, a high voltage is induced in the secondary coil through electromagnetic induction. Induction coils are crucial in physics education, laboratory experiments, and ignition systems for demonstrating and utilizing high-voltage phenomena. They are widely used in applications involving spark generation, ionization, and electromagnetic studies.
