| Abstract | ||
| تم دراسة تّغير تيار التفريغ عبر المجالات المغناطيسية المستعرضة (0-150 كاوس) في العمود الموجب للتفريغ ألتوهجي لغازي N2 و CO2 في مدى الضغوط من (0.75الى 7.5 تور). وقد وجد بان التيار يزداد بصورة تدريجية مع زيادة المجال المغناطيسي إلى أن يبلغ قيمة عظمى عند قيمة محددة من المجال المغناطيسي لكلا الغازين ولا تعتمد على قيمة الضغط لنفس التيار. The variation of discharge current with a transverse magnetic fields (0-150 Gauss) has been studied in the positive column of glow discharge in N2 and CO2 with the pressures range from (0.75 to 7.5 torrs). It is found that the current gradually rises with the increase of magnetic field, and then attains a maximum value at particular value of the magnetic field which is the same for all the two gases. It was found that this value is independent of the pressure for the initial discharge current, and then gradually decreases. | ||
