Dear Alper,
To what I cannot answere is if this magnetic tools work correctly or not. But they do work. F.A. Mesmer used magnets to heal many malfunctions with great success. More than that, in my early years I did used magnets for healing purposes and I find them very helpfull. But the use of a magnet can both benefit or damage the careless user, as they have to be putten correctly. For simple problems and for a sort period of usage, there are some safe techniques.
Now, if used for a very short time, the magnet is going to reduse the tense and there for the pain and for this it will accelerate the self healing ability of the body, and this will be done no matter if it will installed correctly or not, because the magnet will change the magnetic field of the person, and therefor the electromagnetic field, and therefore the aura. And if you put it over an overloads or blocked chakra, it will help and accelerate the balancing. BUT, in order to be beneficial, you must take care, or after the first aid, the magnet may help the person to built a stronger negativity, either emotional, mental or physical.
Oh, by the way, the effects of reducing and increasing the magnetic field of the Earth (reduction is accomplished by installing a magnetic field that opposes the Earths magnetic field and increasing is accomplished by installing magnetic field by Earths magnetic field) have been scientifically checked. These experiments have shown changes to the ability of the five senses, mostly to the sense of vision (this is the only experiment that I know it has been confirmed to humans after the original experiment with mice). Also for the mice in an extended period of living under different magnetic fields it has been noticed difference in the way cancer lumps were progressing and some other biological problems that were fixed, redused, increased or appeared. The official conclusion is that for humans the intensity of the magnetic field has ambiguous effects and the direction of it has no effects.
I am not pleased with this conclusion, as my experience has proved more, but the magnetic fluid, that for me exists, for science does not exist, so it is logical. Also the magnets have many magical powers as well and they can be used to therapeutic magic very easily with quite good results. But I guess these magnetic wrists are not enchanted
In a few words, yes magnets can effect the chakras, the aura and the body, but unless you use them for a few hours now and then, use them with great care.
May Gods bless you all.
Siva.
