Copper is an element number 29 in the periodic table with the element symbol CU. It is considered spongy and known for its good conductivity of electricity. However, for this guide, we will explore the magnetic properties of copper.
Is Copper Magnetic?
No – copper is a non-magnetic metal. This is attributed mainly to its atomic structure. Ideally, copper has an irregular arrangement of electrons inside the atomic structure.
Non-magnetic Properties of Copper
· Diamagnetism
A critical analysis of copper magnetism shows it slightly repels when subjected to a magnetic field. Ideally, this is attributed to the changes that occur in the copper’s orbital spin.
Remember, this unique orbital spin is triggered by the magnetic field. Since copper shows some resistance to magnetic fields, you can classify it as a diamagnetic material.
· Electron Configuration
One of the key factors affecting the copper magnetic properties is the electronic configuration. Therefore, as an element with atomic number 29 and electronic configuration (Ar) 3d104s1, copper remains a non-magnetic metal.
· Alloying Element
Copper in its pure form is a non-magnetic metal. However, alloying copper with other ferromagnetic materials may make it possess some magnetic properties.
Factor Affecting Copper Magnetic Properties
As indicated earlier, copper is a non-magnetic metal. However, some variables may affect this property.
Take for instance:
- Impurities – Adding ferromagnetic impurities may introduce magnetic properties in copper alloys. However, pure copper remains non-magnetic.
- Processing copper – Processing copper may affect copper magnetic properties. That is to say, processes such as cold working, heat treatment, or adding alloying elements may make copper exhibit some magnetic properties.
- Applying magnetic field – Applying an exterior magnetic field makes pure copper exhibit diamagnetic properties. That is, the repulsive nature of copper in the presence of a magnetic field will be evident.
Application of Copper
Audio Equipment
With copper being a good electrical conductor, it improves the performance of audio equipment without the possibility of being affected due to magnetic field or interference.
Aerospace Applications
Most aerospace equipment is sensitive to magnetic interference. Using metal that is non-magnetic or that cannot be magnetized ensures all your equipment is safe from any form of magnetic interference.
Electrical and Electronics
Since pure copper cannot be magnetized, it makes a perfect conductor in most electrical applications.
Conclusion
As you can see, copper is a non-magnetic material. However, in the presence of a magnetic field, it exhibits diamagnetic properties.
