Magnetic Materials

The term "magnetic" refers to a variety of substances that are drawn to magnets. Typically, magnetic fields are created by magnetic materials. They are made up of a variety of materials that have a wide range of applications. Since magnetic materials are frequently used to generate and distribute electricity, they play a significant role in numerous socio-economic factors on a global scale. They are materials that are primarily used and studied for their magnetic characteristics. The inherent angular momentum, or spin, of a material's electrons, determines a major portion of the magnetic response of that material. 

Magnetic Materials Classification

There are two types of magnetic materials: magnetically hard and magnetically soft.

Soft magnetic materials are easily magnetized, but magnetism is typically transient. A strong external magnetic field, such as those produced by an electromagnet, can magnetize magnetically hard materials just like it can magnetically soft ones. The distinction is that magnetically hard materials won't become demagnetized by an opposing magnetic field, heated past their Curie temperature, or exposed to corrosion. Instead, they will continue to be magnetized indefinitely. Permanent magnets are created from alloys often including variable proportions of iron, aluminum, nickel, cobalt, and rare earth metals samarium, dysprosium, and neodymium. These materials are magnetically hard materials.

Application

The expansion of the automotive industry is one of the primary drivers of the growth of magnetic materials. The increase in demand for electricity is another factor. In the recent past, permanent magnetic generators, or PMG systems, were added to wind turbines. The long-term growth of the magnetic material market is anticipated to be fueled by the usage of magnetic materials to replace electricity.

HEVs are more popular since they are economical and environmentally benign, which increases the market's need for magnetic materials. Therefore, the market for these hybrid cars is probably going to lead to increased demand for magnetic materials, which will ultimately accelerate the growth of the worldwide magnetic materials market.

Different kinds of automotive components, including switches, motors, actuators, and sensors, utilise magnetic materials. Additionally, they are utilized in cutting-edge electronic products, banking security systems in the form of smart electronic bank cards, and other anti-theft items. Other uses for magnetic materials include gearboxes, alternators, and pollution control equipment.
