What are the differences in various magnetic field application devices?
For therapeutical purposes, permanent magnets and electromagnetic field devices are applied. The effects of permanent magnets are relatively small, and these systems are not approved as devices of medical technology. For devices of medical technology, pulsing magnetic fields (electromagnetic fields) are used. Pulsing magnetic fields differ mainly in three parameters: The form of the pulse (expansion and/or change of the field, which can be displayed as a wave), The frequency (number of changes per second) and The flow density (force action of the field). With these three parameters, many different magnetic fields can be developed. However, it is these three parameters that decide on the physiological effect of the respective field and whether the field will harm the organism (electro-smog, microwaves, UV radiation, X-rays, etc.) or whether and to what extent it will benefit the organism. In other words, magnetic fields are not equal; the type of the field determines the effect. Unfortu
