Is rust magnetic? ?

Question

Iron oxide, I mean iron is magnetic...Is iron oxide?

If not...why not?

Answer 1

YES!!!

Answer 2

Yes, it still has iron in it.

In fact your hard drive uses ferric oxide (iron rust) to hold its information and allow it to be changed.

According to Wikipedia:  

"Iron(III) oxide is often used in magnetic storage, for example in the magnetic layer of floppy disks. These consist of a thin sheet of PET film, coated with iron(III) oxide. The particles can be magnetised to represent binary data. MICR (Magnetic Ink Character Recognition) also uses iron(III) oxide compounds, suspended in an ink which can be read by special scanning hardware."

Answer 3

As rust contains Iron, you would think it will be magnetic.

But, Rusting and corrosion contain atoms of other elements, mainly Oxygen.

This produces completely new elements that behave differently to the surrounding electrons of neighboring atoms.

Rusty metals become either non-magnetic or much less so than the pure magnetic metal.
