Monte Carlo simulations of electron swarms in oxygen have been performed to study effect of a magnetic field on ozone generation. The result shows that superimposition of the magnetic field perpendicular to an electric field reduces dissociation rate of oxygen molecules. Reduction of the dissociation rate is due to depression of electron energy in the swarm and backscattering of electrons to the cathode. It is also confirmed that a radial expansion of the swarm is constrained in the case of the magnetic field parallel to the electric field.
