ferrite
Ferrite is a type of magnetic material made primarily from iron oxide. It is known for its high magnetic permeability and low electrical conductivity, making it useful in various applications, especially in electronics. Ferrite is commonly used in the production of magnetic cores for transformers and inductors, as well as in permanent magnets.
There are two main types of ferrite: soft ferrite and hard ferrite. Soft ferrites are easily magnetized and demagnetized, making them ideal for high-frequency applications. In contrast, hard ferrites retain their magnetization, which is useful for permanent magnets in motors and speakers.
