 codomain   هم-دمن   ham-damanFr.: ensemble d'arrivée   The set of values that a → function is allowed to take (i.e. may possibly come out of a function), as opposed to the → range.→ co-; → domain. domain   دمن   damanFr.: domaine   1) Math.: The set of x values that can go into a function f(x). Compare with → codomain and → range. 2) Ferromagnetism: → magnetic domain.From M.Fr. domaine "domain, estate," from O.Fr. demaine "lord's estate," from L. dominium "property, dominion," from dominus "master of a household," from domus "house;" cognate with Pers. dam, as below; Gk. domos "house;" O.C.S. domu , Russ. dom "house;" Lith. dimstis "enclosed court, property;" O.E. timber "building, structure"); PIE base *dem-/*dom- "to build."Daman, from Av. dəmāna- "house," dami "in the house;" cf.

It is of finite thickness ans has nonuniform → magnetization.→ domain; → wall. magnetic domain   دمن ِ مغناتیسی   daman-e meqnâtisiFr.: domaine magnétique   Any of several microscopic areas in a → ferromagnetic material that possesses a net → magnetic field, because electron spins are aligned in the same direction. In the absence of an external magnetic field, the directions of the magnetization vectors of the separate domains do not coincide and the resultant magnetization of the whole body may be zero.→ magnetic; → domain.
