Customers often ask about whether the performance grade of magnets can be measured with a Gaussian meter. So can the Gaussian meter judge the grade of the magnet? Today, magnet supplier Courage daisy answers this question for you.
First of all, the answer is no. Using a Gauss meter to measure the magnetic meter can not actually judge the grade of the magnet, in general, can judge the grade according to the Gauss meter, basically very experienced, has seen tens of thousands of magnets may be roughly judged (but not necessarily accurate). If you want to determine the grade of the magnet, you need to measure the demagnetization curve.
Gauss meter can measure the size of the magnetic field, but it cannot be directly used to judge the grade of the magnet.
What is the reason why the Gauss meter cannot judge the grade?
1. Only look at the table magnetic is not accurate, different positions and distance measurement out of the data results are not the same. Surface magnetic measurement can only be used as a general reference, and the results of different brands of Gaussian meters will also appear different data.
2. For the same performance and grade of magnets, if the size, thickness and other values are different, the Gaussian value will be different. In the case of the same grade and shape specifications of the magnet, the thicker the thickness, the greater the surface magnetic (Gaussian value).
Therefore, it is generally difficult to judge the material grade of the magnet from the value measured by the Gauss meter, usually by looking at the magnetic flux.
So what can a Gauss meter be used to determine?
The magnetic data of the Gauss meter can be used to roughly determine whether the magnet is of high quality or poor material. The same specification, the surface magnetic of the magnet of different performance levels is different, in addition, it can also detect the N, S pole of the magnet is on which face, whether it is multi-pole (multiple NS on a surface) and so on.
In short, the Gauss meter can measure the strength of the magnetic field, but it cannot be directly used to judge the grade of the magnet. Judging the grade of magnets requires more professional and accurate test equipment and methods.
