How does a electrical coil work for a 1989 Ford Tempo?

In a 1989 Ford Tempo, the electrical coil, or ignition coil, transforms the battery's low voltage into the high voltage needed to create a spark at the spark plugs. When the ignition system is activated, a current flows through the coil's primary winding, creating a magnetic field. When the current is interrupted, the magnetic field collapses, inducing a high-voltage current in the secondary winding, which is then sent to the spark plugs to ignite the air-fuel mixture in the engine's cylinders. This process is crucial for starting and running the engine efficiently.
