Brit.

/ˈmaɡnᵻtʌɪt/, U.S.

/ˈmæɡnəˌtaɪt/

Origin: A borrowing from German. Etymon: German Magnetit.

Etymology: < German Magnetit ( W. Haidinger Handbuch der bestimmenden Mineral. (1845) 551, replacing earlier Magneteisenstein ) < Magnet magnet n. + -it -ite suffix¹.

Mineralogy.

A strongly magnetic oxide of ferrous and ferric iron, Fe₃O₄, of the spinel group, which occurs as black or brownish-black crystals of the cubic system and is an important iron ore; lodestone.
