Is a magnetic chalkboard a physical characteristic or a chemical one?

Neither properly describes it. All attractions are forces, and there are only four forces in the known universe: gravity, weak nuclear, strong nuclear, and electromagnetic. Magnet attractions are electromagnetic. Both physical forces (that are not gravity) and chemical forces are also classified as electromagnetic forces. So neither physical or chemical properly describes a magnetic force, although classical physics would be more accurate to say than chemical.
