Vertical three-component magnetic field generator

SONG Ji-hong(College of Electronic Information Engineering,Changchun University,Changchun 130022,China)  
The three-component magnetic field generator of orthogonal directions with the known magnetic field intensity is made with the same three groups of Helmholtz coil in the light of structural map.The electric current passed the coil is the variable constant flow source with high precision so as to reduce errors from temperature and other external factors.We conduct constant flow source to the three groups of coil to change the current of constant flow source by adjusting the resistance,so that we can control the strength of three component magnetic field.
