What are the three distinct circuits in a magneto system?

• A. The rotor circuit, stator circuit, and spark circuit.
• B. The charging circuit, the discharge circuit, and the spark circuit.
• C. The magnetic circuit, the primary electrical circuit, and the secondary electrical circuit.
• D. The thermal circuit, the mechanical circuit, and the electrical circuit.

Answer: (C)

In a magneto, energy flow is organized into three distinct circuits: the magnetic circuit, the primary electrical circuit, and the secondary electrical circuit. The magnetic circuit is the path that guides the magnetic flux through the magneto’s core and housing. It uses the magnetic field to link the windings and store energy briefly as the field builds up when the drive energizes the system. The primary electrical circuit is the low-voltage loop. It includes the primary winding and the breaker points (and often a condenser). When the points close, current flows and magnetizes the core. When the points open, the current is interrupted, causing the magnetic field to collapse. The secondary electrical circuit is the high-voltage loop. It consists of the secondary winding and the spark plug circuit. The collapsing magnetic field in the primary (and the energy transfer through the magnetic coupling) induces a high voltage in the secondary, delivering the spark to the spark plug. These three circuits—magnetic, primary electrical, and secondary electrical—describe the essential, separate roles within a magneto. Other terms like “rotor/stator” or “charging/discharging” don’t define the three distinct circuit paths of a magneto.
