Magneto

A magneto is a type of electrical generator that uses permanent magnets to produce alternating current (AC) electricity. Unlike a dynamo, a magneto relies solely on permanent magnets for its magnetic field, not electromagnets. It is commonly used in applications where a reliable and self-contained power source is needed, such as in the ignition systems of gasoline engines, especially older engines, motorcycles, and small aircraft. The device converts mechanical energy into electrical energy directly through electromagnetic induction and is known for its robustness and ability to operate independently of an external power source. The magneto's design and construction make it durable and able to withstand harsh conditions.

Magneto meaning with examples

• The mechanic suspected a faulty magneto was the cause of the engine's failure to start, as the spark plugs weren't firing. The magneto was removed, revealing corrosion and damage to the internal windings. Replacing the magneto resolved the starting issue, showing the component was vital.
• Classic car enthusiasts often maintain their magneto systems meticulously, appreciating their simplicity. The magneto generated the electrical current to run the engine. They're chosen over modern electrical systems. Maintaining the magneto helped keep the cars originality.
• The vintage aircraft relied on its magneto to power the spark plugs and ignite the fuel, a stark contrast to modern jet engines. Magnetos, although old, are very reliable. Pilots trust the magneto for in-flight performance. The pilot performs routine checks.
• In many older motorcycles, the magneto serves as the primary power source for the ignition system and lighting. The magneto produced all the necessary electric power. The maintenance of the magneto is therefore crucial for the bike. Bike collectors still use the magneto.
• The farmer's equipment included a magneto-equipped tractor that consistently started up even in cold weather, attesting to its reliability. The magneto produced power without a battery. The magneto powered the spark plugs and the starting system. The farmer was very appreciative.
