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.

Is steel wool physical or chemical change?
When the steel wool burns, it is oxidized and thus this is a chemical change.
Is melting steel a chemical or physical change?
Physical
Is rusting steel wool a physical or chemical change?
Chemical. Rusting is known as "oxidization," a chemical reaction where oxygen reacts with iron.
Is there a chemical or physical change when a bicycle rusts in the rain?
Rusting is a chemical change, as steel/iron turns into iron oxide.
Is magnetizing steel a physical change or chemical change?
physical, just the aligning of magnetic domains what were previously random in orientation.

Is a tin can rusts a physical or chemical change?
Yes, it is, because the chemical composition of the outside changes due to oxydation.
Is rusting iron a physical change in science?
no rusting iron is not a physical change it is a chemical change
Is converting iron to a steel alloy a physical 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.
What type of change is melting steel?
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.
Is a liquid steel solidifying a chemical change?
No. Any change of state (solid to liquid, liquid to gas, etc.) is a physical change.
Is dissolving steel into acid a chemical change?
no, its physical change :)
