The process of penetrating the magnetic field into the plasma is one of the basic concepts of physics. The magnetic field can improve the confinement of plasma insid tokamak and control the perturbations within the plasma that cause the plasma to cool and become unstable. One of the limitations in plasma that is controlle by the magnetic field is the plasma density limit. The limitation on the maximum plasma density does not increase the density to a desired confinement level. According to the results obtained from this study, it is observe that high density is relate to the second power of magnetic field and the relationship between plasma frequency and density is observed that the magnetic field is related to the frequency of electrons and ions inside. Plasma has a linear relationship and any changes in the magnetic field cause similar changes in the plasma frequency.
