Magnetizing is a physical change.
physical change
Yes, magnetizing iron is a physical change because it does not alter the chemical composition of the iron. When iron is magnetized, its magnetic domains align to create a magnetic field, but the iron itself remains unchanged chemically.
Brittleness is considered a physical change. It is a change that can be felt, and interacting with it does nothing to change it into something else.
Chemical broooooooooooooooo niga
Extraction is considered a physical change because it involves separating substances based on their physical properties, such as solubility or boiling point, without changing the chemical composition of the substances being separated.
According to my Chemistry teacher its physical
Magnetizing doesn't involve a chemical reaction.
physical, just the aligning of magnetic domains what were previously random in orientation.

yes
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.
Evaporation is considered to be a physical change. The chemical nature and identity of the evaporated material is the SAME as that of the liquid.
It's because
Well a chemical change cannot be reversed while a physical change can be, what do you think??
Yes, rotting is considered to be a physical change. However, it's also considered to be a chemical change as well.
