Final answer:
Magnetism is not a physical property of matter as it cannot be observed or measured without changing the identity of the substance.
Step-by-step explanation:
A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. Examples of physical properties of matter include color, hardness, malleability, solubility, electrical conductivity, density, melting point, and boiling point. Based on these examples, we can conclude that magnetism is not a physical property since it is not a characteristic that can be observed or measured without changing the identity of the substance. Instead, magnetism is a physical phenomenon that involves the attractive or repulsive force between objects with magnetic properties.
