Metallographic Preparation of Magnetic Core Samples

Magnetic cores are magnetic components made of ferromagnetic materials (e.g., iron, silicon steel, ferrite), designed to concentrate and guide magnetic fields. They are indispensable core parts in numerous electronic and electrical devices.

Key Functions of Magnetic Cores

  •  Magnetic field concentration: Gather the magnetic field generated by coils to boost inductance, enabling more compact and efficient components.
  •  Energy conversion: Facilitate the mutual conversion of electrical and magnetic energy in transformers and inductors for voltage transformation and energy storage.
  •  Filtering & anti-interference: Suppress high-frequency noise, ensure the smooth transmission of useful signals, and enhance device stability.

Simply put, a magnetic core is the magnetic field manager of electronic devices. By regulating the flow of magnetic fields, it enables voltage transformation, energy storage, filtering and anti-interference in equipment, serving as the cornerstone of modern power electronics and information communication technologies.
