madiha Posted October 10, 2012 Share Posted October 10, 2012 i repeat; if mixtures have properties of their constituents then why is steel not attracted by a magnet? Link to comment Share on other sites More sharing options...
John Cuthber Posted October 10, 2012 Share 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. Link to comment Share on other sites More sharing options...
Enthalpy Posted October 12, 2012 Share 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.
