How Pick-Up Coils Work
The operation of a pick-up coil is based on electromagnetic principles. When the engine runs, the rotor spins within the distributor, and the pick-up coil detects the rotor’s position. This detection is achieved through either a Hall effect sensor or magnetic induction. As the rotor passes by the sensor, it generates a voltage signal that is sent to the ignition control module, which then triggers the ignition coil to produce a spark.
The Hall Effect
The Hall effect is a phenomenon where a voltage is generated across a conductor when it is placed in a magnetic field. In the context of pick-up coils, the Hall effect sensor detects the magnetic field created by the rotor and converts it into an electrical signal. This signal is crucial for the ignition system’s timing and performance.
Applications of Pick-Up Coils
