An experimental study is presented of the electron saturation current arriving at a plane probe situated in a magnetized plasma. Using a simplified Bohm's model, the equations of electron probe current in a magnetized plasma are derived and compared with the experimental results. The equations show that the electron temperature is determined for a sufficiently large range of negative probe potentials and an apparent space potential is lowered by the presence of the magnetic field.
