Abstract <p>The kinetic characteristics of electrons in CO₂/N₂/H₂O mixtures are calculated by numerically solving the Boltzmann equation for the electron energy distribution function in mutually perpendicular electric and magnetic fields. The drift velocity of electrons, their average energy, electron energy balance, and ionization and dissociative attachment rate constants are calculated over a wide range of reduced electric (<i>E</i>/<i>N</i>) and magnetic (<i>B</i>/<i>N</i>) field values as follows: <i>E</i>/<i>N</i> = (0.5–2000) × 10^–17 V cm²; <i>B</i>/<i>N</i> = (0–4000) × 10^‒21&#xa0;T cm³. Based on the results of calculations, the dependence is investigated on the induction of the applied magnetic field, specifically at the critical value of the reduced electric field, defined by the condition of equality between the ionization and attachment frequencies. It is also shown that the influence of the magnetic field <i>В</i> ≤ 3 T on the kinetic characteristics of electrons in the above gas mixtures is low at atmospheric pressure.</p>
