That would be a blast furnace.

It has been found that iron oxide can be magnetized if it is the right kind of iron oxide. We know that iron (III) oxide (Fe2O3) is magnetic, and it can be combined with just a little bit of other stuff to make ferrite, which is commonly used to make magnets.
You should be more specific about what change you are talking about. But let me take a guess. For example, iron plus oxygen can become ferric oxide. Both elements change their names. The change is used to indicate the kind of bonding process that is taking place. When iron and oxygen become ferric oxide, the iron has lost electrons and the oxygen has gained the electrons that iron lost. The change of name tells us that the elements are in an altered state, having turned into electrically charged ions.
synthesis
It's most likely some kind of corrosion caused from oxidation (aka an oxide). For example, with iron (ferrous) based metals it's called iron oxide, commonly called "rust" and is a brownish-red color. On other metals, like aluminum, it is simply called aluminum oxide and is a whitish color. I *suspect* the "white stuff" is the corrosion of aluminum called "aluminum oxide". Could be wrong, but it's the simplest answer. Search Google Images for "aluminum oxide" and see if it's the same stuff. Happy corrosion hunting!
yes. it is the same kind of compound oxide
Iron rusting is a chemical change in which iron reacts with moist air to form fe2o3 commonly known as rust, a brown coloured coating.
NO!!!! It is a COMPOUND. It is made up of two elements. viz. Iron(Fe) and oxygen(O).

The oxidation of the iron in a car door into iron oxide is a chemical change. The reaction equation is 4 Fe + 3 O2 = 2 Fe2O3

FeO3 is a non-exsisting iron oxide.Possible oxides of iron are FeO (ferrous oxide) and Fe2O3 (ferric oxide) and all kind of 'mixtures' of both (oxydules).
Kind of reddish brown. FeO2 is commonly called rust.
Iron Oxide
Iron exists in two oxidation states: Fe2+ and Fe3+. To distinguish between these two oxidation states and to specify which kind of ion will form on dissociation, they are named as Iron II and Iron III. Now, Fe2O3 contains the Fe3+ ion. That is why, it is called iron III oxide.
Yes, we can see the use of iron oxide (the Fe2O3 kind, which is iron (III) oxide) used in magnets. There are a number of different things that could be used in a magnet, but simply using this material, often referred to as ferrite, and a little bit of some other materials to make up the ferrite, will allow for the construction of a magnet.

Oxidation. Water, oxygen, and metal.
