madiha Posted October 10, 2012 Posted October 10, 2012 i repeat; if mixtures have properties of their constituents then why is steel not attracted by a magnet?
John Cuthber Posted October 10, 2012 Posted October 10, 2012 It's often not. It's also difficult to say whether an alloy is a mixture or not. Some are clearly defined inter-metallic compounds.
Enthalpy Posted October 12, 2012 Posted October 12, 2012 The question is imperfectly clear, since most steels are attracted by magnets... Basically, ferromagnetism is a molecular property, not an atomic one. For instance, austenitic stainless steel is non-magnetic. But Mn-Zn makes a ferromagnetic alloy called "ferrite" by thankful electronics engineers. You may understand "molecular property" as "not a result of constituents" if you wish.
