Introduction to magnetic performance testing instruments

Currently, commonly used magnetic performance testing instruments on the market include flux meters, Hall effect magnetic field measuring instruments, current transformers, Faraday current inductors, etc.

Among them, the magnetic flux meter is a widely used instrument. It uses an electromagnet to generate a magnetic field, adjusts the magnetic field strength by adjusting the electromagnet current, and then uses a probe to measure the magnetic flux. By measuring the changes in magnetic flux under different currents, the magnetic property parameters such as remanence and coercivity of the material can be calculated.

In addition, the Hall effect magnetic field measuring instrument is also a commonly used magnetic performance testing instrument. It uses the Hall effect to measure the strength and direction of the magnetic field. When electrons pass through the Hall element, the electrons will be deflected by an angle due to the effect of the magnetic field. By measuring the size of this angle, the strength of the magnetic field can be calculated.

It should be noted that different magnetic property testing instruments may have different characteristics such as applicable material range, testing accuracy and price. Choosing the appropriate instrument requires comprehensive consideration based on specific application requirements.

What does the BAIJIAN inspection report do? What problems can it help you solve?

1. Sales report. (Sales need to provide third-party test reports to make their products more relevant and let the product data speak for themselves.words to make customers more confident in the quality of their products. )

2. R&D report. (In the process of developing new products, we encountered some thorny issues about ingredients. We used third-party testing data to find the cause of the problem, solve the problem in a timely manner, shorten the R&D cycle, and reduce R&D costs)

3. Improve products quality. (Discover problems with your own products through comparison of third-party testing data, improve product problems, improve quality, and reduce production costs)

4. Use of scientific research paper data.
