What You Need to Know About Gauss

Many companies that use magnets in manufacturing use the word "Gauss" every day. Some people may not know that the term originated from a German mathematician named Karl Friedrich Gauss, who used mathematical principles to measure magnetism. Of course, if you don't have those special trifles, you might be able to make it. More importantly, we need to know what Gauss means and what it does not mean. Surprisingly, even in companies that rely on magnetic components, the term is often misunderstood.
Essentially, Gauss refers to the intensity of the magnetic field, in other words, the magnitude of the magnetic field in a given region. A Gaussian unit is a flux line in a surface area of 1 square centimeter. Another method is to consider the flux density. So if you can imagine a candy bar and a flux line from the Arctic to the Antarctic, it's Gauss. It is not necessarily related to the distance to which the magnetic field arrives, but the distance will be proportional to the magnetic flux density and the geometric structure of the magnet. In more professional terms, Gauss is still a measurement of field strength; it is a position variable and a vector (directed), which means that different positions in space have different Gauss readings and related directions. Generally speaking, Gauss is different from the tensile strength of magnets. Higher Gauss does not necessarily lead to higher tensile strength. Gauss readings are used in applications where the field strength is the main parameter, such as sensor applications. In most cases, the Gauss level cannot be used to compare the magnetic field strength between magnets unless the magnets have the same geometric structure and the Gauss readings are measured at the same position. In measurement terms, Gauss, G or GS for short, is the CGS unit of magnetic field B, also known as "magnetic flux density" or "magnetic induction". A Gauss is defined as a Maxwell per square centimeter. CGS system has been expanded by the SI system, which uses Tesla (t) as the unit of B. A Tesla = 10,000 Gauss! Well, back to Earth. Because the Earth's magnetic field is about 0.5 Gauss, and the refrigerator magnet you bought from the local pizza store is 10 Gauss, you may be wrong to conclude that the magnet in Al Pisa is stronger than that on Earth. That's a terrible idea. The magnetic field can reach anywhere in a space, but its intensity decreases as the distance increases. That's why airfreight sets a certain Gaussian value at a distance of 15 feet. Usually, the Gaussian level is very small at this distance and can only be measured by a very accurate and sensitive Gaussian meter. The calculation may help to estimate the field strength at the distance, but shielding/packaging will not be considered. Manual computing is a long and difficult process. Fortunately, Adams provided a shortcut: a free magnetic field calculator for Gaussian level and tension measurements. Our calculations are based on the size and material type of a single magnet.
