Application of Magnetic Materials in Industry

In fact, magnetic materials can be seen everywhere in our life, such as Fe3O4, that is, rust. It is a natural magnet can be seen everywhere in our life. In our industrial production, magnetic materials are extensively and ubiquitously applied. For instance, a generator for power generation, a transformer for power transmission, a motor for cars, and a telephone we use to make phone calls at ordinary times are all common things in our daily life, which cannot be produced without magnetic materials. It can be proved that our industrial manufacture cannot be separated from magnetic materials. Because many devices and equipment need coil structures, without magnetic materials we cannot electrify modern life, and our life will lack fun in a large amount. This shows the importance of magnetic materials to traditional industries.

In fact, a lot of medical equipment are also made of magnetic materials. For example, in medicine, we can diagnose abnormal tissues of human body by observing magnetic resonance imaging, a technology we are familiar with, so as to diagnose diseases.

With years of development, great progress has been made in the research of bio-magnetic materials. Although many bio-magnetic materials are still in the testing stage, I believe that in the near future, with the development and progress of bio-engineering, material engineering and biomagnetism, the magnetic properties of materials will be more widely used in clinical trials, thus making greater contributions to the development of medicine.

The 21st century is an era of rapid development of science and technology. On the basis of high technology, the strength of a country’s military is related to the country’s international status. A country’s strong military strength means that the country is in an invincible position in economy, culture and other aspects. Magnetic materials are also widely used in military affairs, such as the use of radar and electromagnetic guns. Magnetic materials can be said to have contributed to enhancing the military strength of various countries.
