Plug Coil is a high voltage (Low Current) transformer. However it is for conversion of vehicle’s volts power supply. From 12 volt to 25-30,000 volts required to jump the gap of the spark plug.
Therefor, The plug coil is nothing but a type of a Step-up Transformer with 2 sets of windings, The current is made to flow in the primary coil and causes a magnetic field around the secondary coil.

However, Plug coil system required mechanical contact breaker points and a capacitor (condenser).
A modern passenger automobile may use one plug coil for each engine cylinder (or pair of cylinders), eliminating fault-prone spark plug cables and a distributor to route the high voltage pulses,
plug coil consists of a laminated iron core surrounded by two coils of copper wire. An Ignition Coil serves to generate the very high voltage (~30,000 V ). Required to cause a spark to jump across the spark-plug electrodes.
The plug coil is nothing but a type of a Step-up Transformer with 2 sets of windings, The current flows in the primary coil and causes a magnetic field to be created around the secondary coil. A contact breaker then suddenly cuts the current in the primary coil and the magnetic field collapses very fast. Fast changing magnetic field causes a very high voltage on the secondary winding that connects to the spark-plug.
plug coils are of varnish and paper insulated high-voltage windings. Inserted into a drawn-steel can with oil or asphalt for insulation and moisture protection.
