Static magnets or PEMF?
This website is not be complete without a few words on regular static magnets sold for treatment of all kinds of diseases and are known as magnet therapy or magnetic therapy.
Powerful permanent [static] magnets are manufactured with a combination of neodymium, iron and boron materials [NdFeB] and are also known under the name of rare earth magnets.
They are supposed to have "wonderful" healing effects but explanations on how these healing effects are supposed to be obtained are not substantiated with any sound scientific proof.
We see these static neodymium magnets websites wrongly quoting scientific studies based on with PEMF.
Hereunder a good scientific article going somewhat deeper into explanations on the differences between PEMF and static magnetic fields.
Static Magnetism versus Pulsed Magnetic Therapy in Medical and Veterinary Use
Dr. D.C. Laycock PhD, BEd(Hons) Member of the International Society for Bioelectromagnetism
This article is written to try to answer some of the questions posed about the efficacy and use of static magnets versus pulsed magnetic fields in both medical and veterinary use.
Magnetism is a product of moving charged particles. This can be within a conductor, such as a length of wire carrying an electric current, or found around certain types of materials where the crystal structure is such that a current is formed by electrons, sharing the orbits around the atoms making up the structure in an orderly direction. In a conducting wire a source of energy, i.e. a battery, is required to sustain the flow of electrons in order to overcome the natural resistance, whereas in a magnet, electrons freely orbit their atomic crystal structure, unaffected by any resistance. The flow of electrons in a magnet requires no external input of energy but the field produced is constant and as such has no dynamic component and is therefore not a source of energy in itself. When a constant flow of electrons through the wire is sustained, then the fields produced are identical in nature between the static magnet and the ‘induced’ field.
Pulsating magnetic fields differ in that they rise and fall around the conductors or coils as the current through them is varied.
Static magnets are widely available for use in both the medical and veterinary fields with many claims made for their efficacy, but are such magnets of any real use? How do they work and where and when should they be applied?
