1) How to understand Gauss
Gauss is the unit of magnetic field. This unit is part of the Gauss unit system, which is a continuation of the older CGS-EMU system. 5000 Gauss represents your magnet, the highest magnetic field is 5,000 Gauss. But be careful if you use a gaussmeter to check the magnetic field strength. That is, measure the Gaussian value at a certain point. That is, the magnetic field strength at a certain point on the magnet is 5000 Gauss, but the Gauss values at other points may be different.
2) How many gauss can NdFeB magnet reach?
This question is very general and people don't know how to answer it to your satisfaction. Because the magnetic level of a magnet is related to many factors, such as the grade of the magnet, the specifications of the magnet, the thickness, etc. But we have collected some common magnet Gauss specifications for your reference
For example, the N35 Gauss material of D10*4 can reach about 3000-3200, and the Gauss of D10*5 can reach about 3400-3600.
The surface magnetic field of a single NdFeB magnet is 3000-7000GS, ferrite 300-800GS, samarium cobalt, and Alnico 2000GS. NdFeB should be considered a very high permanent magnet, but it is difficult to reach more than 5,000.
3) What is the largest Gaussian magnet?
N35 and N38 can reach about 2000GS. If the size is larger, the N35 can reach up to 3500GS and the N38 can reach 3800GS. If someone tells you that he can make a big magnet with 10,000 gauss, you must marry him first because he has new technology. Generally speaking, the Gaussian surface of a magnet is inversely proportional to the area and directly proportional to the thickness.
