In a Hall generator, output current is produced by leveraging the Hall effect, which occurs when electrons in the plasma experience a force along the channel due to the presence of magnetic and electric fields.1

Unlike a standard Faraday generator, the Hall generator configuration operates by short-circuiting the Faraday field across each sector of the channel. By connecting these sectors in series, the system allows for the connection of a single electric load between the ends of the channel, utilizing the Hall field—an electric field established along the axis of the channel—to drive the output current.1
