Health magnet magnetic medical use health in modern medicine not only has important applications luggage magnets, such as magnetic resonance imaging magnet bags Which benefits, often called MRI CT (computerized tomography), and MCG Fig and magnetoencephalography applications, but there is a long history. In the Western Han Dynasty "Historical Records" (about 90 BC) in the book "public warehouse Biography" will be referred to the king serve the medical use of five kinds of mineral drugs (called five stone) treatment. The five mineral medicine refers magnet (Fe3O4), cinnabar (HgS), realgar (As2O3), alunite (aluminum potassium sulfate) and Zeng Qing (2cuCo3). Then there are the ancient healing magnet application records. Ferrite magnet is a ferromagnetic metal oxide. On the electrical characteristics, the ferrite resistivity than metal, alloy magnetic material much luggage magnets Which concessions, but also a higher dielectric properties. The magnetic ferrite having a high performance can be further permeability at high frequencies. Thus, a wide range of high-frequency ferrite has become weak areas of use of non-metallic material. Belongs to non-metallic magnetic material is iron oxide and one or more metal oxides other composite oxide (positive or ferrite). 800-1000 gauss magnetic generally, often used in speakers, speakers and other equipment.
