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 has? 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:
What Is Gauss
Gauss is a unit of the magnetic field. This unit is part of the Gaussian system of units, which was inherited from the older CGS-EMU system. 5000 Gauss represents your magnet with a maximum magnetic field of 5,000 Gauss. But please note,if you use a gauss meter to check the magnetic strength field. That is to measure the Gauss value of a certain point. It means that the magnetic field strength of a certain point on the magnet is 5000 Gauss, while the Gauss value of other points is not the same.
How Much Can Gauss Be Achieved By Magnetism?
This question is very general, and we don’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 Gauss material can reach about 3,000-3,200 Gauss, 10 * 5 to about 3,400-3,600 Gauss.
The surface magnetic field of a single NdFeB magnet is 3,000-7,000G, ferrite 300-800G, samarium cobalt, and AlNiCo 2,000G. Neodymium iron boron should be considered a very high permanent magnet, but it is difficult to reach 5,000 or more.
How Many Gauss Magnets Are big?N35 and N38 are probably up to 2,000GS. If the size is bigger, N35 can reach 3,500GS at most, and N38 can reach 3,800GS. If there anyone tells you that he can produce a large magnet with 10,000 gausses, you must marry him first, because he has new technology.
In general, the Gauss surface of the magnet is such that it is inversely proportional to the area and is proportional to the thickness.
How to check Gauss value?
We usually use a Gauss meter to measure the Gauss magnet surface. However, the Gauss values measured at different positions on the surface of the magnet are different, the Gaussmeters have different measured data, and the error is relatively large.
What Is The Difference Between A Gauss Magnet And A Magnetic Flux?
Both Gauss and flux measurements are made to determine the performance of the magnet. The reproducibility of magnetic flux is better than Gauss, more stable, and the error is not too big.
Note: Gauss (Gs) is the unit of measure for magnetic field lines. 1T=10,000 Gs
What Is Milligauss?
1Gauss = 1,000 Milligauss
Ordinary gauss meters cannot measure. It should be a dedicated tool to check it. This is a fairly small unit of measurement that the average citizen does not need to use. The more commonly used situation is to measure whether the magnetic field strength of a package meets the shipping standards of the IATA (International Air Transport Association). The IATA requires that the magnetic field of the package cannot exceed 0.00525Gauss (525Milligauss)
What Is Tesla?
10,000gauss= 1 Tesla
10 Gauss = 1 Mt
Tesla is the new unit of the International System of Units (SI). This is why we can see that some products are sometimes expressed as Tesla and sometimes as Gauss to express the magnetic field strength.
