A magnet keeper, or armature is a ferromagnetic bar made from soft iron or steel which is placed across the poles of a permanent magnet to help preserve the strength of the magnet by completing the magnetic circuit; it is particularly useful for magnets which have a low magnetic coercivity, such as Alnico magnets. magnet keeper, or armature is a ferromagnetic bar made from soft iron or steel which is placed across the poles of a permanent magnet to help preserve the strength of the magnet by completing the magnetic circuit; it is particularly useful for magnets which have a low magnetic coercivity, such as Alnico magnets.
Magnet therapy is the application of the magnetic field of electromagnetic devices or permanent static magnets to the body for purported health benefits.Some believers assign different effects based on the orientation of the magnet; under the laws of physics, magnetic poles are symmetric.agnet therapy is the application of the magnetic field of electromagnetic devices or permanent static magnets to the body for purported health benefits.
