A low-frequency (100 kHz) ferromagnetic enhanced nitrogen inductive discharge has been experimentally investigated in the nitrogen pressure range of 5–55 Pa and discharge current density of 20–80 mA/cm 2 . Dependence of the discharge electric field strength E on the gas pressure was measured for various discharge currents. Dependence of the neutral gas temperature on the gas pressure and discharge current was determined using optical emission spectroscopy, from the measured 0–0 vibro-rotational band of the second positive system of molecular nitrogen (C 3 Π u –B 3 Π g ). Based on the determined neutral gas temperatures, values of the reduced electric field strength E / N were calculated.
