For Health Magnets What Does Gauss Rating Mean?
The magnetic gauss rating is the amount of magnetic energy a particular material can store. Basically it represents the energy measurement inside a magnet, at its core. Because magnets are made from many types and grades of material, each magnet has a different gauss rating.
Gold and its different karat ratings is measured in a simlar way (10k, 14k, 18k, 24k). Magnets have different quality grades. The higher the grade the more powerful the magnet, which means that it will be able to store more energy, and will have a higher gauss rating.
However the size of a magnet is also important. Gauss rating only indicates the strength inside a magnet's core. Even on the surface of a magnet, the real gauss level is only about 8% - 28% as strong as a magnet's gauss rating.
Therefore magnetic field strength is determined by: a. Gauss Rating - how much energy a type of magnetic material can store b. Magnet Size - how much magnetic material is available Without both pieces of essential information, you cannot tell how strong a magnet will be.It is also important to be aware that some companies try to hide the fact they use smaller magnets. They either: a) only provide gauss rating, and do not list size of magnets at all, or b) provide gauss rating and diameter - but do not list the magnet thickness. If the magnets used are very small or thin, the magnetic fields will be very small and weak. Example: A small, (1/2" dia. x 1/16" thick) health magnet (10,000 gauss) may work well for fingers or toes, but offers almost no benefit for knee or back pain.
Most sports injuries and conditions are located far deeper within the body - in muscles, bones, ligaments, tendons, nerves and the spine. A small magnetic field cannot possibly penetrate deep enough to reach these areas.
When buying magnetic bracelets in particular be sure to ask what size the magnets are before making a final decision. In many cases a larger magnet with a low gauss rating can be stronger than a smaller magnet with a high gauss rating.
