induction coil
Voltage-boosting wire loop
An induction coil is a device that transforms low-voltage direct current into high-voltage alternating current through electromagnetic induction.
A primary coil wrapped around an iron core creates a magnetic field that induces current in a secondary coil with many more windings, dramatically stepping up the voltage.
Induction coils were essential to early radio transmitters, spark-gap systems, and the ignition systems of internal combustion engines.
