No Battery? No Problem. Why Your Lawnmower (and a Dragster) Love Magnetos

In simple terms, a magneto is a self-contained electrical generator that uses permanent magnets to produce periodic pulses of alternating current. While it sounds a bit "steampunk", it’s a brilliant piece of engineering because it doesn't require a battery to start or run an engine. Click to read more.
