The core is provided with an inner hole, and the inner hole is provided with an arc-shaped limit groove, such as transformers, inductors, motors, generators and magnetic amplifiers. The core enhances the magnetic flux density of electromagnetic equipment through its magnetic conductivity, thereby improving its electromagnetic effect and efficiency. The core material is usually composed of silicon steel, iron-nickel alloy, iron-silicon alloy and ferrite, etc., with the characteristics of high magnetic permeability, low loss and high saturation magnetic flux density.
