physical, just the aligning of magnetic domains what were previously random in orientation.
Physical change, because it's not changing what makes up the magnet
Magnetizing is a physical process.
it is freezing in texes

A clean stainless steel bowl will not cause chemical contamination, which is why you use them.
Steel wool is made of small ribbons of steel, and steel is an alloy of iron with a percent or so of carbon. There will be some traces of other metals in it as well. As steel is mostly iron, we might be tempted to write Fe as the chemical formula for steel, but this isn't technically correct. Steel is a metal alloy, and as such, it doesn't have a chemical formula as it is a mixture of materials.
The most common, FeS
Tempered steel has both strength and the ability to change form under the right amount of pressure. Tempered steel can be made from both low carbon and high carbon steels.
Stainless steel is ferrous, you can pick it up with a magnet, also it won't tarnish like silver, unless it's a plated silver spoon, if there is such a thing.

Magnetizing a piece of steel, a needle for example, is a physical change, for it causes the spin of a group of electrons to be co-alignedrather then randomly oriented. The chemical composition of the steel is unchanged.
It's because

When the steel wool burns, it is oxidized and thus this is a chemical change.

Chemical. Rusting is known as "oxidization," a chemical reaction where oxygen reacts with iron.
Rusting is a chemical change, as steel/iron turns into iron oxide.

Yes, it is, because the chemical composition of the outside changes due to oxydation.
no rusting iron is not a physical change it is a chemical change
It is a physical change as an alloy is a solid solution made from various metals. As you can still separate these different metals after the alloy is made it is a physical change and not a chemical change.
