Although the energy problem is one of the main difficulties of the cosmological interpretation of quasar red-shifts, there is no need to go beyond conventional physical laws in seeking an explanation. Various proposals have been made which differ in important details. I believe a suitable basis for a theory of quasars to be a supermassive plasma configuration, the matter of which is in mostly regular motion in a magnetic field. Such a magnetodynamic configuration I shall call a ‘magnetoid’. On this model a quasar is a galaxy with a dense non-stellar nucleus, the magnetoid, which gives rise to the characteristic non-thermal luminosity. The mass of the quasar is determined by its stars while the parameters of the magnetoid depend on the stage of evolution or conditions of formation in a similar way to those of radiogalaxies or active nuclei of galaxies.
