Magnetism is a physical property that is mediated by magnetic fields.
The magnetic state of a material depends on temperature (and other variables, such as pressure and the applied magnetic field), so a material may exhibit more than one form of magnetism depending on its temperature, etc. However, a material's magnetism doesn't change the composition, and doesn't involve a chemical reaction.

What is building a tower of magnetic blocks Physical or chemical change?
Building a tower of magnetic blocks is a physical change because the blocks are simply being rearranged without any chemical reactions taking place. The properties of the blocks themselves remain the same.
Is magnetizing a paper clip considered physical or chemical change?
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.
Is magnetization of an iron nail a chemical change?
physical change
Is an ionic bond a physical change?
No, an ionic bond is a type of chemical bond formed between two ions with opposite charges through electrostatic attraction. It involves the transfer of electrons between atoms, making it a chemical change rather than a physical change.
Is heating a bar magnet chemical or physical change?
Heating a bar magnet is a physical change because the magnet does not undergo a chemical reaction. The heat energy causes the atoms in the magnet to vibrate, which disrupts the alignment of the magnetic domains within the magnet, thereby reducing its magnetic strength.

Is The magnetization of an iron rod an example of a chemical change?
No. Iron is naturally magnetic.

Is the magnetism of a strip of iron chemical or physical change?
The magnetism of a strip of iron is primarily a physical change. When iron is magnetized, the alignment of its internal magnetic domains changes, allowing it to exhibit magnetic properties. This process does not alter the chemical composition of the iron; thus, it remains a physical transformation rather than a chemical one.
Is an ionic bond a physical change?
No, an ionic bond is a type of chemical bond formed between two ions with opposite charges through electrostatic attraction. It involves the transfer of electrons between atoms, making it a chemical change rather than a physical change.
Is crush a physical change?
Crushing creates a physical change in the size of the pieces but it does not change their chemical make up.
What type of change occurs when a needle is magnetized is it physical or chemical?
Magnetization of a needle is a physical change because it does not involve any chemical reactions. The alignment of the magnetic domains within the needle is rearranged to make it magnetic, but the composition of the needle remains the same.
Is heating a bar magnet chemical or physical change?
Heating a bar magnet is a physical change because the magnet does not undergo a chemical reaction. The heat energy causes the atoms in the magnet to vibrate, which disrupts the alignment of the magnetic domains within the magnet, thereby reducing its magnetic strength.
