The Gauss. The strength of the magnetic field
The Gauss is nothing more than the unit used to measure the strength of a magnetic field and gaussmeter the instrument used to make that measurement. The higher the number of Gauss, the more force the magnetic field will have, so the greater the distance will be reached from the surrounding magnet. This measure is what we will usually find in magnetic products dedicated to medical and health applications. In those magnetotherapy devices.
The name Gauss comes from the German astronomer and also physicist and mathematician, called Johann K. Friedrich Gauss, born in 1777 and who died in 1885. The Gauss, as we know it today, can be said to be the unit with which the intensity of a magnetic flux is measured. However, we must indicate that the other unit of measurement of the magnetic field is the Tesla, which measures the intensity of the magnetic flux in the same way. It usually does so in a square meter. In general terms the following conversion is applied to determine that 1 Tesla is about 10,000 Gauss.
We can say that the earth’s magnetic field of 0.5 Gauss. On the other hand, a small magnet can reach 100 Gauss and if it is neodymium up to 2000 Gauss. To calculate the value of Gauss in a magnet it is advisable to do it in the surface, since it is much more fair, that to a few millimeters.
On the surface the Gauss value of a magnet is more exact than a few millimeters. For this reason we indicate that the value of Gauss depends on the distance between the magnet and the place of application. The distance of the magnetic flux – calculated in Gauss – decreases depending on whether there is more or less distance.
Most magnets, even the smallest ones, have 1000 Gauss on the surface. But depending on the magnetizing force it is possible that one magnet only generates 100 Gauss at a distance of 10 mm, while another is able to generate 1000 Gauss.
It is important to note that some manufacturers indicate a number of Gauss units in the magnets that can only be achieved if that magnet reaches a short circuit state and only if there is a small air gap between the North Pole and the South Pole. We must know that this value cannot be reached on the surface or with a magnet that acts in a more independent way.
At IMA we try to inform all our customers of the measurements, strength and power of the magnets in the correct and realistic way. With precision and indicating to all our customers the information with the greatest transparency, so that they know, at all times, what type of products they are buying, and what kind of results can be expected according to what they have purchased. We know that many companies do not act in the same way and that sometimes the information offered by others seems, at least in theory, more attractive because the label they provide is substantially embellished. We prefer that the information received is as accurate as possible, so that the expectations are real and match what is going to be acquired. In any case, before the doubt, we always recommend that you consult us and ask us as many times as you deem necessary. We are committed to our customers and we like the attention you receive to match our products. So, if any information is not clear or does not resolve your doubts, do not hesitate to make your query to clear any doubt. We will be delighted to help you
