What material is the iron core?

Iron core is a material widely used in electronic components.
It is usually made of iron, nickel, aluminum, cobalt and other metals. Due to its high magnetic permeability and small hysteresis, iron core has been widely used in electronic components such as transformers, inductors, and filters.
The function of the iron core is to enhance the induction intensity of the electromagnetic field, thereby improving the efficiency of transformers and inductors. The principle is to introduce a magnetic field into the iron core to orient the atomic magnetic moments inside the iron core, thereby increasing the magnetic flux and increasing the intensity of electromagnetic induction.
The magnetic permeability of the iron core is an important parameter that affects its performance. The higher the magnetic permeability, the less energy the iron core needs to consume when magnetizing, so the higher its efficiency. In addition, the saturation magnetic induction intensity of the iron core is also one of the important parameters affecting its use. When the magnetic induction intensity in the iron core exceeds the saturation magnetic induction intensity, the iron core will enter a saturated state, resulting in circuit distortion and reduced efficiency.
In short, iron core, as an important electronic component material, is widely used in electric power, communications, computers and other fields. With the continuous advancement of technology, the performance of iron cores is also constantly improving, and more application scenarios will appear.
