Magneto FAQs:

Q: Is a Magneto an electrical generator that uses permanent magnets to produce periodic pulses of alternating current?

A: Yes.

Q: Were Magnetos limited to narrow fields?

A: Yes, and such as powering arc lamps or lighthouses, where their particular features of output stability or simple reliability were most valued.

Q: Are Magnetos used in piston aircraft engines for their reliability and simplicity?

A: Yes, and often in pairs.

Q: Are Magnetos not used in highway motor vehicles which have a cranking battery and which may require more control over ignition timing than is possible with a magneto system although sophisticated solid state controllers are becoming more prevalent?

A: Yes.

Q: Were Magnetos also adapted to produce pulses of high voltage in the ignition systems of some gasoline-powered internal combustion engines to provide power to the spark plugs?

A: Yes.

Q: Were Magnetos used for specialized isolated power systems such as arc lamp systems or lighthouses?

A: Yes, and for which their simplicity was an advantage.
