Ignition Coil: Description and Operation
View: Ignition Coil
PURPOSE
The Ignition Coil transforms battery voltage (primary circuit) into ignition voltage (secondary circuit) and delivers it in the form of a high voltage
surge to the secondary ignition components.
CONSTRUCTION
The Ignition Coil is encased in plastic resin instead of an oil filled case. The primary winding is made of a approximately one hundred turns of
wire. The secondary winding contains several thousand turns of wire wound directly onto the iron core. The ratio of the number of wraps in the
secondary winding to the number of wraps in the primary windings determines the output voltage of the coil.
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.
