Etymology

The word "magnet" comes from the Greek word "μαγνῆτις λίθος" (magnē̂tis líthos), which means "Magnesian stone". This is a reference to the Magnesian region of Greece, where lodestone was first found. Lodestone is a naturally occurring magnet that was used by the ancient Greeks to make compasses.

The Greek word "μαγνῆτις λίθος" is thought to be derived from the name of the Magnesian tribe, the Magnetes. The Magnetes were a people who lived in the Magnesian region of Greece. They were known for their use of lodestone, and they were said to be able to control the movement of iron with their magnets.
