means Magnets are objects or materials that produce a magnetic field, pulling iron-based metals toward them and either attracting or repelling other magnets.

from From the Greek 'Magnes lithos,' meaning 'stone of Magnesia' — a region in Asia Minor (in what is now Turkey) where ancient people found lodestones, naturally magnetic rocks of iron ore, that mysteriously clung to iron. The Greeks already noticed these stones tugged at metal without touching it; the word traveled through Latin 'magnetum' and Old French before settling into English. There's an old folk tale of a shepherd named Magnes whose iron-nailed sandals stuck to the ground, but that's a charming legend layered onto the truer, duller fact: the stones were simply named for where they were dug up.
