Final answer:
The three main circuits of a high tension magneto system are the primary circuit, the magnetic circuit, and the secondary circuit.
Step-by-step explanation:
The three main circuits of a high tension (magneto) system are:
- The primary circuit, which is responsible for initial electrical power generation.
- The magnetic circuit, which includes the magnets and the magnetic field paths associated with the magneto.
- The secondary circuit, which is where the high voltage is induced and then directed to the spark plugs.
Magnetos are essentially self-contained electrical generators that utilize magnetic induction to generate high-tension electricity. They play a crucial role in the ignition systems of various engines, particularly in aviation where reliability and self-sufficiency are paramount. Magnetos operate independently of the aircraft's electrical system, ensuring that the engine can run even if other electrical systems fail.
