Ferroelectric cathodes in a transverse magnetic field up to 3kG were experimentally investigated. The observed diffusive light emission from the surface was found similar to light emission in preflashover mode of the surface breakdown. The results indicated the similarity of the dark emission mode to the surface preflashover, where the transverse magnetic field inhibited the development of secondary electron avalanches along the surface.
