In this paper, We measure the plasma parameters using a single probe to study the characteristics of our designed magnetic control direct current glow discharge experimental device. We can obtain the relationship between the electron density and pressure, the electron density distribution and the magnetic field type, the electron density distribution, the magnetic field strength, etc. In addition, magnetic field generated by coils is calculated by the finite element method , through which the distributions of two magnetic fields with different connection modes are simulated. In experiment the states of the plasma are controled partly by these two different types of magnetic field position, and this “control” role is consistent with existing theory.
