the only rock that earned a permanent argument with iron.
means A material or object that produces a magnetic field, attracting iron and certain other metals (and aligning compass needles).
from From the Greek 'magnes lithos' — the 'stone of Magnesia,' a region in ancient Thessaly where these curious iron-grabbing stones were dug up. The name traveled through Latin 'magnetem' and into English, carrying its hometown with it; the related word 'magnesium' and even 'manganese' grew from the same Greek soil.
