# What is gauss in magnet business

In this business, we often hear about Magnet Gauss, but we have a question now, what is Gauss? How much can Gauss be achieved with magnetism? How do we know how much Gauss does the magnet have? How much can Gauss be used for the commonly used N35 and N38? In this post, we would like to explain it to you, one by one in an easy way:

1. What is Gaussian
Gauss is a unit of magnetic field. 5000 Gauss represents your magnet with a maximum magnetic field of 5,000 Gauss.
2. How much can Gauss be achieved by magnetism?
This question is very general, and we do n’t know how to answer it and make you satisfied. Because the magnet’s magnetic level is related to many factors, such as the grade of magnets, the specifications of the magnet, the thickness and so on.
But we have collected some common specifications of magnet Gauss for your reference
Such as 10 * 4 N35 Gaussian material can reach about 3000-3200 Gauss, 10 * 5 to about 3400-3600 Gauss.
The surface magnetic field of a single NdFeB magnet is 3000-5000G, ferrite 300-800G, samarium cobalt, and AlNiCo 2000G. Neodymium iron boron should be considered as a very high permanent magnet, but it is difficult to reach 5000 or more.
3. How many Gaussian magnets are the largest?
N35, N38 is probably up to 2000GS. If the size is bigger, N35 can reach 3500GS at most, N38 can reach 3800GS. If there anyone tells you that he/she has a magnet above 10,000 gausses, you must marry him first, because he has new technology.
In general, the Gaussian surface of the magnet is such that it is inversely proportional to the area and is proportional to the thickness.
4. How do you know how big a Gaussian magnet is?
We usually use a Gauss meter to measure the Gaussian magnet surface. However, the Gaussian values measured at different positions on the surface of the magnet are different, and the Gaussmeters have different measured data, and the error is relatively large.
5. What is the difference between a Gaussian magnet and a magnetic flux?
Both Gaussian and flux measurements are made to determine the performance of the magnet. The reproducibility of magnetic flux is better than Gaussian, more stable, and the error is not too big.
Note: Gaussian (Gs) is the unit of measure for magnetic field lines. 1T=10000 Gs
