The influence of magnetic field on DC radial glow plasma was studied by self-designed coaxial glow discharge device, and the influence of magnetic field on the spatial distribution of plasma density is studied. The experimental results show that the spatial density distribution of plasma from cathode to anode increases gradually in the high-intensity magnetic field, and decreases gradually in the absence of magnetic field. Theoretical analysis of the above results show that the high-intensity magnetic field increases the moving path of the electrons, enhances the collision efficiency between the electrons and the neutral atoms, and makes the discharge plasma density remarkably enhanced.
