Physical
The simple act of melting the steel is a physical change. No one melts steel out of boredom. If the melt is so you can add other elements to it, then you've made a chemical change. If you're forming useful products from the steel without changing its chemistry, it's a physical change.
No, shaping of steel is a physical change, not a chemical change. The steel's chemical composition remains the same before and after shaping, only its physical properties, such as shape and size, are altered.
physical, just the aligning of magnetic domains what were previously random in orientation.
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.
Yes, a crushed can has chemical properties. They are the same as those of the can before crushing. Crushing a can is a physical reaction and not a chemical one. For instance, if a soup can is made of steel, the steel can be chemically attacked by something like sulfuric acid. And this is true whether the can is crushed or not.
Melting the steel wool is a physical change.

When the steel wool burns, it is oxidized and thus this is a chemical change.
no, its physical change :)
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.

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
