What are the magnetic components

Magnetic components are electronic components made of the characteristics of magnetic materials, and are usually used to realize the conversion of various signals such as magnetic fields, electric fields, and sound fields. Common magnetic components include the following:
Inductor: usually composed of a coil, consisting of two parts: magnetic material and winding wire. Mainly used to block alternating current or transform current and voltage.
Magnetic bead: It is a small magnetic material, usually in the shape of a sphere, which can be used for noise filtering, EMI/EMC suppression, attenuation of common mode noise, etc.
Magnetic ring: It is a ring-shaped component made of magnetic material, usually used to make magnetic cores of transformers, inductors and other components to improve their magnetic field transmission efficiency.
Magnetic patch: It is a thin magnetic component, usually made of thin magnetic material, and its magnetic performance is equivalent to that of a conventional ferrite core. Magnetic patches are commonly used to make broadband inductors.

Magnetoelectric Acoustic Device: It is often used as a speaker or microphone. When the magnetic field changes, the electrical signal or voltage generated can be converted into a sound field or an electric field.
Magnetic sensor: It is a sensor based on magnetic materials, which can be used to sense the strength and direction of the magnetic field, and is widely used in the field of automatic control and detection.
Soft magnetic material: It is a magnetic material with high magnetic permeability, which is usually used to make magnetic cores and switches to improve the performance of high frequency applications.
In conclusion, magnetic components play a vital role in the electronics manufacturing industry, realizing multiple functions such as signal transmission, conversion and filtering in the circuit. Through the combination and design of different components, various functions such as electromagnetic equipment, electronic instruments, automatic control and signal processing can be realized, which has played an important role in promoting modern society and production.

client purchase strong magnets"Since 2006, we found Mr.Guo and get products from him. We used magnets under the earth for the gas and water pipe industries. We have met no problem. We have been working in very happy ways. We have many cooperation. Every year, we spent time together and sometimes, we invited him to Korea. He is our younger brother. Strongly recommended!!"

customers buy permanent magnets"I had email to Mr. Guo for rare earth magnet requirements. They replied my e-mail promptly, and were very professional. Mr. Guo’s team still continues to deliver rare earth magnets to our agreed specifications with a very high quality standard since 2012. His team is very professional and thorough with its work. Based on my experience, I would highly recommend them."
