Magnetic Core Sample Preparation
A magnetic core (Magnetic Core) is a magnetic component made of ferromagnetic materials (such as iron, silicon steel, ferrite, etc.). Its main function is to concentrate and guide the magnetic field. It is an indispensable core component in many electronic and electrical devices.
The main function of the magnetic core is to concentrate the magnetic field: to gather the magnetic field generated by the coil together, increase the inductance, and make the component smaller and more efficient. Energy conversion: responsible for the mutual conversion of electrical energy and magnetic energy in transformers and inductors, completing functions such as voltage transformation and energy storage. Filtering and anti-interference: suppressing high-frequency noise, allowing useful signals to pass smoothly, and improving equipment stability.
In simple terms, the magnetic core is the "magnetic field manager" of electronic devices. It manages the flow of the magnetic field to help the equipment achieve voltage transformation, energy storage, filtering, and anti-interference, and is the cornerstone of modern power electronics and information communication technologies.
The following are the sample preparation parameters and the analysis of the metallographic effect for the magnetic core samples:
● Grinding: MET-SP P600-2500
● Coarse polishing: SC + 3μm PD-WT
● Fine polishing: SC + 1μm PD-WT
● Final polishing: ZN + SO-A439
