How Many Gaussian Magnets are Qualified?
How many gauss does a magnet have to qualify? Seeing that some netizens are asking, do you also want to know? Next, the Chinese magnet manufacturer HSMAG will introduce this problem to you.
1. Magnet Gauss value is not fixed
The Gauss value of the magnet depends on the material, specification, performance level, etc. of the magnet, and it does not have a fixed value.
2. How much is the Gauss value of the magnet qualified?
Gauss requirements for magnet
The figure above shows that the customer requires the magnet Gauss to be 1000 ± 200 Gauss
The Gauss value that meets the customer’s requirements is qualified, whether it is 200 Gauss or 5000 Gauss. This is because different customers have different Gauss requirements for magnets, and some customers have high requirements and cannot be low. Some requirements are low, and high is not enough. Some customer requirements cannot be high or low, within a certain range.
Gauss’s law for magnetism states that no magnetic monopoles exists and that the total flux through a closed surface must be zero. This page describes the time-domain integral and differential forms of Gauss’s law for magnetism and how the law can be derived. The frequency-domain equation is also given. At the end of the page, a brief history of the Gauss’s law for magnetism is provided.
The above is the relevant introduction about how many Gaussian magnets are qualified. Our company specializes in various neodymium strong magnets, ferrite magnets, motor arc magnets, multi-pole ring magnets, welcome to inquire.
Gauss’s law for magnetism is a physical application of Gauss’s theorem (also known as the divergence theorem) in calculus, which was independently discovered by Lagrange in 1762, Gauss in 1813, Ostrogradsky in 1826, and Green in 1828. Gauss’s law for magnetism simply describes one physical phenomena that a magnetic monopole does not exist in reality. So this law is also called “absence of free magnetic poles”.
People had long been noticing that when a bar magnet is divided into two pieces, two small magnets are created with their own south and north poles. This can be explained by Ampere’s circuital law: the bar magnet is made of many circular currents rings, each of which is essentially a magnetic dipole; the macroscopic magnetism is from the alignment of the microscopic magnetic dipoles. Because a small current ring always generates an equivalent magnetic dipole, there is no way of generating a free magnetic charge. So far, no magnetic monopole has been found in experiments, despite that many theorists believe a magnetic monopole exists and are still searching for it.
However, as pointed out by Pierre Curie in 1894, magnetic monopoles can exist conceivably. Introducing fictitious magnetic charges to the Maxwell’s equations can give Gauss’s law for magnetism the same appearance as Gauss’s law for electricity, and the mathematics can become symmetric.
