Definition of Fe3O4

Fe3O4
Magnet Mag"net, n. [OE. magnete, OF. magnete, L. magnes, -etis, Gr. ? ? a magnet, metal that looked like silver, prop., Magnesian stone, fr. Gr. ?, a country in Thessaly. Cf. Magnesia, Manganese.] 1. The loadstone; a species of iron ore (the ferrosoferric or magnetic ore, Fe3O4) which has the property of attracting iron and some of its ores, and, when freely suspended, of pointing to the poles; -- called also natural magnet. Dinocrates began to make the arched roof of the temple of Arsino["e] all of magnet, or this loadstone. --Holland. Two magnets, heaven and earth, allure to bliss, The larger loadstone that, the nearer this. --Dryden. 2. (Physics) A bar or mass of steel or iron to which the peculiar properties of the loadstone have been imparted; -- called, in distinction from the loadstone, an artificial magnet. Note: An artificial magnet, produced by the action of a voltaic or electrical battery, is called an electro-magnet. Field magnet (Physics & Elec.), a magnet used for producing and maintaining a magnetic field; -- used especially of the stationary or exciting magnet of a dynamo or electromotor in distinction from that of the moving portion or armature.
Fe3O4
Magnetite Mag"net*ite, n. (Min.) An oxide of iron (Fe3O4) occurring in isometric crystals, also massive, of a black color and metallic luster. It is readily attracted by a magnet and sometimes possesses polarity, being then called loadstone. It is an important iron ore. Called also magnetic iron.
Fe3O4
Multiple Mul"ti*ple, a. [Cf. F. multiple, and E. quadruple, and multiply.] Containing more than once, or more than one; consisting of more than one; manifold; repeated many times; having several, or many, parts. Law of multiple proportion (Chem.), the generalization that when the same elements unite in more than one proportion, forming two or more different compounds, the higher proportions of the elements in such compounds are simple multiplies of the lowest proportion, or the proportions are connected by some simple common factor; thus, iron and oxygen unite in the proportions FeO, Fe2O3, Fe3O4, in which compounds, considering the oxygen, 3 and 4 are simple multiplies of 1. Called also the Law of Dalton, from its discoverer. Multiple algebra, a branch of advanced mathematics that treats of operations upon units compounded of two or more unlike units. Multiple conjugation (Biol.), a coalescence of many cells (as where an indefinite number of am[oe]boid cells flow together into a single mass) from which conjugation proper and even fertilization may have been evolved. Multiple fruits. (Bot.) See Collective fruit, under Collective. Multiple star (Astron.), several stars in close proximity, which appear to form a single system.
