Abstract: Magnetically stabilized fluidized bed （MSFB） is a new type of reactor, which combines the advantages of both fixed bed and traditional fluidized bed, and has a great application prospect. In this paper, the progress of basic research and application of MSFB is reviewed. The basic research includes effects of fluid flow rate and magnetic field intensity on fluidization behavior of the magnetic particles in the column, bed voidage, operation stability and transfer characteristics. The application fields include biochemical engineering, energy and environmental engineering. Finally, the existing drawbacks of MSFB are presented. It remains difficult to find the relevant magnetic catalyst in a specific reaction system. MSFB can not be operated at a temperature higher than the Curie temperature of magnetic carrier. The heat generated by the magnetic field generator has an effect on the magnetic carrier and the reaction process and it is difficult to determine the stable operating zone of MSFB. The main research directions of MSFB in the future are proposed, including research and development of magnetic catalyst，stability criterion，mechanism of heat transfer and mass transfer，mechanism of strengthening reaction process，scale-up of reactor and design of industrial reactor.
