Is Magnet and sand chemical or physical cahnge

The interaction between a magnet and sand is primarily a physical change. When a magnet is brought near to iron-containing sand, the magnetic properties of the iron particles cause them to be attracted to the magnet. This does not involve any chemical reaction or change in the composition of the substances involved. The sand remains sand, and the magnet remains magnetized. Therefore, it is a physical change, characterized by a change in the position or state of the materials without altering their chemical structure.
