Gauss - What is it?
Magnetic flux density is the strength of the magnetic field a magnet produces. Will it pick up a paperclip or will it pick up a car.
The most widely used unit of magnetic flux density is the tesla (T) ;
A gauss is 1/10,000th of a tesla.
A fridge magnet probably has a magnetic field of 10 to 15 gauss.
The internal strength of the magnet may be far more gauss than that, but the surface gauss is what is useful to you in a practical sense. When someone states that a magnetis is so many gauss it might be useful to ask if that is the surface gauss or the internal gauss that they are measuring. If it's the internal gauss, then you need to know what the external gauss is.
If you have two magnets with a surface gauss of 3000 and they are stuck together, they may be quite hard to pull apart.
Magnetic therapy jewelry usually uses magnets from five hundred to two thousand gauss at their surface. Stronger magnets can penetrate deeper. Usually you are trying to get the magnetic field to penetrate your blood at a pulse point.
Magnetic bracelets are the most common magnetic therapy jewelry used. A magnetic bangle will usually have a magnet on each end, and these should be close to the two pulse points on your wrist. Here the magnetic field can affect what is happening in the blood flowing by under those pulse points.
I sell both link bracelets with 6 magnets in them and bangles with two magnets in them. My personal opinion is that the bangles are more effective - the magnets are positioned just where they need to be positioned. Magnets on the top of your wrist are likely doing nothing for you! That said, looks are important when we are wearing jewelry, so if a link bracelet style suits you better, go for it. Even if the magnets aren't in the optimum place for you, the two nearest the pulse points should definately help.
