What's the difference between magnesia and magnet?

Magnesia


Definition:

  • (n.) A light earthy white substance, consisting of magnesium oxide, and obtained by heating magnesium hydrate or carbonate, or by burning magnesium. It has a slightly alkaline reaction, and is used in medicine as a mild antacid laxative. See Magnesium.

Magnet


Definition:
