Can anyone tell me about a magnet that makes the camshaft sensor fire plugs in 93 Ponitiac Grand Am?

There is no magnet that makes the camshaft sensor fire spark plugs in a 1993 Pontiac Grand Am. The camshaft sensor is a passive device that detects the camshaft's position and sends this information to the engine's computer, which then uses it to control the fuel injectors and ignition timing. There are no magnets involved in this process.
