In the mining industry, ferromagnetic particles (e.g. magnetite) are concentrated using wet low-intensity magnetic separation (LIMS). Mineral particles in suspension with water are pumped into the separator tank, and a magnetic concentrate is extracted by use of magnetic forces. The performance of the process is to a large extent controlled by ...

In low and high frequency PEMF therapy devices the magnetic field is measured in Gauss. Clinical studies have demonstrated the effectiveness of magnetic fields from very low intensities (from 5 gauss up to 300 gauss). However, there is no direct relationship between intensity and duration of treatment.

Drum separators are most common low intensity wet magnetic separators. They consist of a rotating non-magnetic drum containing three to six stationary magnets, either permanent or electromagnets, of alternating polarity. Magnetic particles are lifted by the magnets and pinned to the drum and are conveyed out of the field leaving the gangue particles. Water is introduced into the machine to ...
Magnetic separation using wet high-intensity technique has become one of the most suitable methods for recovery of iron from low-grade ores [6], due to its better separation efficiency as compared ...
Magnetic Intensity. Magnetic field intensity (H) at any point in the magnetic field is defined as the force experienced by the unit north pole at that point. In simple terms, it is a measure of how strong or weak any magnetic field is. The SI unit of magnetic field intensity …
One such possibility is an application of a pulsed magnetic stimulation (PEMF) in the region of the head, which can be classified also as a low-intensity rTMS. Magnetic stimulation of the head region usually utilizes relatively high intensities of magnetic fields of low frequencies and may have multiple healing effects, especially with ...
Here, we show, in vivo and ex vivo, that repetitive transcranial magnetic stimulation at low-intensity (LI-rTMS) induces axon outgrowth and synaptogenesis to repair a neural circuit. This repair depends on stimulation pattern, with complex biomimetic patterns being particularly effective, and the presence of cryptochrome, a putative ...
Scientists developed a high-performance, low magnetic-field MRI system that improves image quality of the lungs and other internal body structures. The technology could be used for image-guided procedures and other new clinical applications in the future. The study may lead to new clinical uses for MRI.
Newer low- or pulsed-field magnetic stimulation (LFMS, PMF) delivers diffuse low-intensity stimuli (μT-mT range, E ≤ 1 V/m) that are also biologically effective: modifying cortical function (Capone et al., 2009; Robertson et al., 2010), brain oscillations (Cook et al., 2004; Modolo et al., 2013) and metabolism (Volkow et al., 2010), as well ...
also evidence that low intensity magnetic fields alter levels of biochemicals that function in neuronal processes, for example, low intensity magnetic fields modulate the level of the primary metabolite of serotonin, 5-HIAA, in rat brain in a dose (time)-dependent manner (Shahbazi-Gahrouei et al., 2016).
Low intensity repetitive magnetic stimulation of neural tissue modulates neuronal excitability and has promising therapeutic potential in the treatment of neurological disorders. However, the underpinning cellular and biochemical mechanisms remain poorly understood. This study investigates the behavioural effects of low intensity repetitive magnetic stimulation (LI-rMS) at a cellular and ...

High intensity separators are used for paramagnetic materials of lower magnetic susceptibility. Both low and high intensity separations may be carried out either wet or dry. Some very large wet high intensity magnetic separators have been applied in the separation of paramagnetic components.
Magnetic separators that used permanent magnets could generate fields of low intensity only. These worked well in removing ferrous tramp but not fine paramagnetic particles. Thus high-intensity magnetic separators that were effective in collecting paramagnetic particles came into existence. These focus on the separation of very fine particles ...
Extremely low intensity magnetic fields are akin to a whisper in the body, and tend to require more specific frequencies, or a wider range of frequencies. Natural cellular communication takes place at extremely low intensity levels, and therefore it only takes a small level of increased energy to help to support and improve some basic cellular ...
Introduction . Tobacco consumption is one of the main causes of mortality in the world. Because of its effect on health, smoking cessation should be prioritized as an important health intervention; however, current interventions have shown low success rates as only 31% of the cases can stop smoking. In this paper, an intervention with high frequency and low intensity transcranial magnetic ...

In research settings, "low intensity" magnetic fields seem to be categorized as those at or around 15 gauss (1,500 microTesla). One study compared a 0.5 gauss (15 microTesla) PEMF with a 15 gauss (1,500 microTesla) PEMF system used for six hours per day for 90 days in …
Repetitive transcranial magnetic stimulation (rTMS) is increasingly used as a treatment for neurological and psychiatric disorders. Although the induced field is focused on a target region during rTMS, adjacent areas also receive stimulation at a lower intensity and the contribution of this perifocal stimulation to network-wide effects is poorly defined.
Low and High Intensity devices also differ in their methods of creating and delivering the magnetic field. Low Intensity devices are resonant systems, and High Intensity devices are impulse systems. Resonant systems deliver a magnetic field through repeated waveforms, …
