As a materials science expert, I've spent a considerable amount of time studying the properties and interactions of various materials, including metals and their responses to magnetic fields. Let's delve into the fascinating world of magnetism and how it relates to copper.
Magnetism and Metals
Magnetism is a fundamental force of nature that arises from the motion of electric charges. It's a property of certain materials that allows them to attract or repel other materials. Metals, such as iron, cobalt, and nickel, are known for their ferromagnetic properties, which means they can be attracted to magnets and can also become magnetized themselves.
Copper and Magnetism
Copper, on the other hand, is a diamagnetic material. Diamagnetism is a property that causes a material to create an induced magnetic field in opposition to an externally applied magnetic field. This property is quite weak and is not as strong as the ferromagnetic properties of other metals. In the case of copper, it does not have unpaired electrons in its electron configuration, which is a requirement for a material to exhibit strong magnetic properties. The absence of unpaired electrons means that copper cannot be magnetized in the same way that ferromagnetic materials can.
Interaction with Magnets
When considering whether copper can stick to a magnet, we must understand that this sticking is not due to the copper's inherent magnetic properties but rather due to other forces at play. For instance, if a magnet is pressed against a copper surface, there might be a slight attraction due to the magnet's field inducing a weak, temporary magnetic field in the copper. However, this is not a permanent or strong attraction and is vastly different from the way ferromagnetic materials interact with magnets.
Applications and Observations
In practical applications, copper is often used in electrical wiring and electronics because of its excellent conductivity and not because of any magnetic properties. In fact, its diamagnetic nature can be beneficial in certain situations where magnetic interference is not desired. For example, in high-precision scientific instruments, using copper can help reduce the impact of stray magnetic fields.
Misconceptions
It's important to clarify that the statement "In their natural states, metals such as brass, copper, gold, and silver will not attract magnets" is accurate. However, the reason is not that they are "strong metals" but rather that they lack the necessary magnetic properties to be attracted to magnets. Magnets are specifically attracted to materials with unpaired electrons that can align with the magnetic field, which is not the case with copper.
Conclusion
In conclusion, copper does not stick to magnets due to any inherent magnetic properties. Its diamagnetic nature means it will not be attracted to magnets in the way that ferromagnetic materials are. Any observed interaction between copper and a magnet is likely due to other forces or a temporary induction of a weak magnetic field, which is not sufficient for permanent adhesion.

In their natural states, metals such as brass, copper, gold and silver will not attract magnets. ... Magnets only attach themselves to strong metals such as iron and cobalt and that is why not all types of metals can make magnets stick to them.
