## Main Question or Discussion Point

Hello all,

I am trying to calculate the plasma beta in a specific plasma temperature. for the plasma pressure i am using the formula p=(ni*kB*Ti)+(ne*kB*ne) and for the beta i am using β=(2*μ0*p)/B^2. I plotted an excel sheet for different values of the magnetic field and realized that the higher the magnetic field the lower the beta. I'v read that for better tokamaks, a beta close to 1 is needed and also a high magnetic field. How is this going to work? Unless I am missing something or misread some information. Any help?
