Why isn't rust attracted to a magnet?

Answer 1

Rust is mostly hydrated Fe2O3 and is not "ferromagnetic" (forming strong magnetic fields) because the atoms of iron are separated by the atoms of oxygen (and molecules of water). However, rust (and the Fe2O3 mineral hematite) responds to an electromagnetic field, and the weak attraction is now being used to separate hematite from waste ore, increasing the amount of iron extracted from a given amount of ore.

Answer 2

Mainly because rust isn't magnetive. Other than that, the properties aren't made up for the magnetic field--but that's saying the same thing.

Rust is somewhere between a metal and non-metal. Its property introduces new atoms and elements, in which forms new chemicals with a changing electron interaction. And if you're curious, electrons have primary roles in generating magnectism.

Mind you, not all rusts are unable to attract magnets. All they have to do is paint their faces in make-up and swagger their hips! No, sorry, utterly lame joke. But in all scientific seriousness, some rust can attract magnetics.

Answer 3

Rust is primarily composed of iron oxide, which is not magnetic. Although iron itself is magnetic, once it oxidizes to form rust, it loses its magnetic properties. So rust is not attracted to magnets because it lacks the magnetic behavior of pure iron.

Answer 4

Yes, rust will cause a magnet to be less effective.
