Equation shows that D B increases, rather than decreases, with temperature , and though it decreases with B, it decreases more slowly than expected. In absolute magnitude, D B is also much larger than D ⊥. For instance, for a 100-eV plasma …

The diffusion of plasma across a magnetic field was conjectured to follow the Bohm diffusion scaling as indicated from the early plasma experiments of very lossy machines. This predicted that the rate of diffusion was linear with temperature and inversely linear with the strength of the confining magnetic field. … See more Bohm diffusion is characterized by a diffusion coefficient equal to $${\displaystyle D_{\rm {Bohm}}={\frac {1}{16}}\,{\frac {k_{\rm {B}}T}{eB}},}$$ where B is the magnetic field strength, T is the electron gas … See more Generally diffusion can be modeled as a random walk of steps of length $${\displaystyle \delta }$$ and time $${\displaystyle \tau }$$.
