alloys repeated ques

[madiha]

i repeat; if mixtures have properties of their constituents then why is steel not attracted by a magnet?

[John Cuthber]

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]

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.
