Ignition Coil: Description and Operation

PURPOSE

The ignition coil transforms battery voltage (primary circuit) into ignition secondary voltage (secondary circuit) and delivers it in the form of a
high voltage surge to the secondary ignition components.

OPERATION

Current flow through the primary winding is stored as a magnetic field. When current flow in the primary winding is interrupted, the magnetic field
collapses, inducing a voltage surge into the secondary windings.
