Magnetization: meaning, definitions and examples
🧲
magnetization
[ ˌmæɡnɪtaɪˈzeɪʃən ]
physical phenomenon
Magnetization refers to the process by which a material becomes magnetized, meaning it acquires a net magnetic moment. This can occur in various materials when they are exposed to a magnetic field, causing the alignment of magnetic moments within the material. It plays a crucial role in fields such as electromagnetism and materials science.
Synonyms
magnetic induction, magnetic polarization
Examples of usage
- The magnetization of iron increases in a strong magnetic field.
- Magnetization affects how materials respond to external magnetic forces.
- The rate of magnetization can vary depending on the material.
- Scientists are studying the magnetization of nanomaterials for technological applications.
Etymology
The term 'magnetization' originates from the word 'magnet', which comes from the Latin 'magnes', meaning 'magnet'. The concept of magnetization has roots in ancient Chinese philosophical texts, where magnetic properties of certain materials were first observed. The understanding of magnetization evolved significantly during the 19th century with the development of electromagnetic theory, particularly through the works of scientists like Hans Christian Ørsted and James Clerk Maxwell. The term began to appear in scientific literature as more was discovered about how certain materials could be made magnetic and how they responded to magnetic fields. Over time, the term has seen application in various interdisciplinary studies ranging from physics and engineering to geology and medicine, emphasizing its importance across different domains of science.
