Ferrites are ceramic compounds composed of iron oxide combined with metallic elements that exhibit ferromagnetic properties, making them crucial in magnetic applications. They are used extensively in electronics for inductors, transformers, and magnetic cores due to their high magnetic permeability and low electrical conductivity, which minimizes eddy current losses.

Electronics is the branch of physics and engineering that deals with the behavior and movement of electrons in semiconductors, conductors, and vacuum. It encompasses the design and application of devices, such as transistors, diodes, and integrated circuits, which are fundamental to modern technology and communication systems.

electronics

Inductors are passive electrical components that store energy in a magnetic field when electrical current flows through them, primarily used to manage current and filter signals in circuits. Their behavior is characterized by inductance, which opposes changes in current, making them essential in applications like transformers, chokes, and tuning circuits.

inductors

Transformers are a type of neural network architecture that excels in processing sequential data by leveraging self-attention mechanisms, enabling them to capture long-range dependencies more effectively than previous models like RNNs. They have become the foundation for many state-of-the-art models in natural language processing, including BERT and GPT, due to their scalability and ability to handle large datasets.

transformers

Magnetic cores are materials around which coils are wound to enhance the magnetic field generated by an electric current, commonly used in transformers, inductors, and electromagnets. They are typically made of ferromagnetic materials like iron or ferrite to optimize magnetic permeability and minimize energy losses due to hysteresis and eddy currents.

high magnetic permeability

low electrical conductivity

Eddy current losses occur in conductive materials when they are exposed to changing magnetic fields, causing circulating currents that generate heat and lead to energy dissipation. These losses are significant in electrical machines and transformers, and are minimized by using laminated cores or materials with high electrical resistance.
