How does a Faraday MHD generator differ from a Hall MHD generator?

Magnetohydrodynamic (MHD) generators are designed to accommodate the Hall effect—a phenomenon where electrons in a plasma flow at an angle across the channel due to the presence of both magnetic and electric fields—in different ways.1

The primary differences between a Faraday generator and a Hall generator are their configurations and how they extract electrical power:

• Faraday Generator: This configuration features electrode walls that are segmented and insulated from one another to support the axial electric field. Electrical power is extracted through a series of individual loads.1
• Hall Generator: In this configuration, the Faraday field across each sector of the channel is short-circuited, and the sectors are connected in series. This design allows for the connection of a single electrical load between the two ends of the channel.1

By utilizing these distinct configurations, engineers can effectively manage the Hall field that is established along the axis of the channel during operation.1
