The aircraft piston engine magneto has a magnetic rotor and an ignition circuit with a reconfigurable charge coil inductively coupled to the magnetic rotor. The charge coil is inductively powered by the magnetic rotor and includes multiple coils that are electronically reconfigurable from a high-turn, low-current power coil for use during low-speed operation to a low-turn, high-current power coil for high-speed operation. The charge coil is configured to a high-turn coil by electronically connecting multiple coils in series or a low-turn power coil by electronically connecting coils in parallel. The ignition circuit is a fully electronically controlled ignition circuit that uses only non-mechanically operated electrical components within the magneto to generate and distribute ignition pulses to the piston engine spark plugs.
