When it comes to magnetic therapy products, each product or device has a specifically designed, and measurable Gauss rating. The Gauss rating of a magnet is a direct measure of how strong its particular magnetic field is. The higher the Gauss rating of a magnet, the more powerful it is, the deeper its effects can penetrate, and the further away its magnetic field can be measured.
Gauss rating is determined and defined by each manufacturer of magnetic therapy products, and this rating is used to essentially let consumers know what the intensity of the magnetic field of the product should be. Basically, the higher a gauss rating is for a magnetic therapy product, the higher the intensity of the therapeutic effects of the product are supposed to be..
Many people may be under the impression that all magnets are pretty much the same, and that they are made from the same material. However, this is not the case. In fact, different types of materials are utilized in the creation of different magnets. These materials directly affect what the gauss rating is for the magnetic therapy product.
Two of the most widely used types of magnets which are used in the manufacture of biomagnetic products are ceramic and neodymium magnets. Each of these types of magnetic materials have magnetic fields of different levels of intensity. Of these two types of magnets, neodymium magnets have a much more intense and powerful magnetic field – up to nearly 13,000 Gauss, while magnets composed of ceramic have natural occurring magnetic fields that are not nearly as powerful – up to a rating of about 4,000 Gauss.
Also, keep in mind that multiple magnets used in a magnetic therapy product do not add their strength together and increase the Gauss rating of the magnetic product itself. For example, a magnetic wrap which contains 10 spot magnets, each with a Gauss rating of 1000, does not have a total Gauss rating of 10,000. Products should not be advertised as having a Gauss rating which combines the strengths of its individual magnetic components.
