Magnetizing is a physical process.
Magnetizing a paper clip is considered a physical change. This is because the process of magnetization does not alter the chemical composition of the paper clip. The magnetic properties are induced by aligning the magnetic domains within the material, which is a reversible process. Chemical changes, on the other hand, involve the formation of new substances with different chemical properties.
Magnetizing doesn't involve a chemical reaction.
physical, just the aligning of magnetic domains what were previously random in orientation.

According to my Chemistry teacher its physical
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.
A metal Surface being ground is a physical change, not a chemical 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.

No, it is a chemical change. The metal oxide formed is a new substance.
