nam châm
/ˈmæɡnət//ˈmæɡnət/The word "magnet" derives from the ancient Greek word μαγνήτης (magnētēs), which meant "auspicious" or "fortunate." This term was used to describe a mineral called lodestone, which was discovered in Magnesia, an ancient region in what is now western Turkey. Lodestone, a type of iron ore found in magnetite, has the remarkable property of attracting other iron-containing objects. Greek sailors first encountered this unique mineral around the Mediterranean, and they believed that the stone had mystical properties due to its attraction of iron. The use of the stone in navigation was not immediately understood, as the sailors didn't realize at first that it was the mineral itself and not some supernatural power that was drawing their ships to it. This led to the ancient Greeks associating lodestone with strength, power, and luck, giving the mineral its fortunate and auspicious name. Over time, the word "magnētēs" came to be applied not only to the mineral but also to other objects that shared its magnetic properties. This evolution in meaning contributed to the modern use of "magnet" to describe any object that is capable of attracting nearby metal.
