Ferrite
Ferrite is a type of magnetic material primarily composed of iron oxide. It is known for its ability to retain magnetism and is commonly used in various electronic components, such as inductors and transformers. Ferrite materials can be categorized into soft ferrites, which are easily magnetized and demagnetized, and hard ferrites, which maintain their magnetism.
Ferrite is often used in the production of ceramic magnets and is essential in the manufacturing of magnetic cores for electrical devices. Its properties make it valuable in reducing energy losses in high-frequency applications, contributing to the efficiency of modern electronics.
