Two Types Of Power generators: Diagram, left above, shows conventional steam turbine, which produces electric power when the turbine blades are rotated in a magnetic field. The other diagram illustrates magnetohydrodynamic (MHD) power, produced when a hot, electrically conducting gas passes through a magnetic field.
