• axial magnetic fields (AMFs)
• ferromagnetic material
• high-current diffuse arc
• vacuum arc

It is well known that axial magnetic fields (AMFs) can keep vacuum are in diffuse mode at high current. According to our recent research and other published papers, it has. been found that vacuum arc can be maintained in high-current diffuse mode at much higher current if nonuniform AMF is applied, that the axial,magnetic field is higher at I contact periphery than at center.
The influence of spatial distribution of AMF on vacuum are is mainly studied in this paper.,Furthermore, two types of AMF contacts with new structures to generate nonuniform AMF are presented.
