Mihajlo Pupin Institute magnets – technical specifications
A magnet used as a source of a magnetic field in AKMA (acupuncture magnet) magnets is designed through a technology applied to the, so called, isotropic barium ferrite which is adjusted to specific conditions so as to achieve certain properties of AKMA.
The chemical formula of this material is BaFe12O19, and the crystal structure is hexagonal. The physical properties are very similar to ceramic, i.e. it is brittle, it doesn’t conduct electricity, and its weight is 4,7 grams per cubic centimeter.
The magnetic properties of this material are:
- Remanent induction Br =0,2-0,22 T (2000-2200 G )
- Coercive field Hc=120-144 kA/m (1600-1800 Oe)
- Energy product (BH) max = 6,4-8 kJ/m3 (0,8-1 MGOe)
- Curie temperature, i.e. the temperature at which the magnet loses its magnetic properties is 450° C
- Surface magnetic flux density is 60 mT (600 Gausa)
- Temperature coefficient of remanence TKBR = -0,2 % / °C
Magnets with a static magnetic field Br = 60 mT have been used for the research. The static magnetic field affects cells and blood. It affects cells by increasing membrane transport and by doing that it improves metabolism. Due to differently charged ions blood flow accelerates which in turn increases nutrients available to tissues.
The static magnets AKMA are produced in more shapes and dimensions. Static magnets with a diameter of 6 mm which are uni- convex with an action radius of 17 mm and depth of action of 10 mm, and magnets with a diameter of 12 mm, with action radius of 35 mm and depth of action of 20 mm have been used for this research.
The chemical formula of the material is BaFe12O19. Aside from the effect of the magnetic field, by pressing the magnet an acupressure effect may be achieved at the bioactive points on the skin. Chemically, these magnets are inactive, they do not oxidize, they are resistant to organic dissolvers, acids and moisture. They do not cause allergic reactions nor do they conduct electricity. They are firm, stable, durable and tenable in oral fluids. These magnets are isotropic magnets, they are stamped without the influence of a magnetic field and their magnetic properties are equal in all directions.
