Magnetic Field Measurement Technology
Magnetic field measurement technology is a technology that uses magnetic fields for detection and measurement, and is widely used in the fields of physics, engineering, medicine, and biology. With the continuous advancement of technology, the magnetic field measurement technology is also constantly improving and developing, which is mainly reflected in the following aspects:
Improvement of magnetic field measurement accuracy: With the development of precision machining technology and digital processing technology, the accuracy of magnetic field measurement instruments has been significantly improved, so that the magnetic field and magnetic field changes can be measured more accurately. For example, the SQUID superconducting fluxmeter, which is commonly used in modern times, has the characteristics of high sensitivity, wide measurement range, and fast response speed, and has become an important tool for magnetic field measurement.
Diversification of magnetic field measurement technology: With the needs of various fields, magnetic field measurement technology is also increasingly diversified. For example, magnetic field measurement technologies such as magnetoresistors, Hall elements, magnetic transmission sensors, and magnetic control manufacturing are widely used. At the same time, various new sensing materials and sensing technologies are constantly emerging, such as ultra-sensitive magnetic field detectors manufactured by nanotechnology, magnetic measurement technology based on spintronic properties, and so on.
Development of visualization and imaging technology: Visualization and imaging technology is a technology that converts measurement results into human-visible forms, and it is also an important direction for the development of magnetic field measurement technology. For example, magnetic resonance imaging (MRI) technology combines magnetic field measurement and imaging technology, allowing doctors to observe the internal conditions of the human body non-invasively, thereby improving the accuracy of medical diagnosis.
In general, with the continuous development of science and technology, the progress of magnetic field measurement technology is also accelerating, thus improving the application of magnet technology in industry, medicine, biology and other fields, and driving the innovation and development of magnet technology.
"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!!"

"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."
