Abstract

This study involves obtaining homogeneous electromagnetic field near a bed of metallic particles using two coils, by varying the distance between the coils and the intensity of the electric field. Mapping and measurement of the coaxial electromagnetic field were performed in the axial and radial directions of the magnetic field lines to determine the magnetic induction and to verify the electrical resistance. These results are important for designing an installation for the fluidization of metallic particles and for predicting the behavior of a magnetically stabilized fluidized bed (MSFB). Experimental determinations were carried out to identify the specific dynamic parameters in the MSFB by measuring the pressure drop and gas velocity as functions of the particle bed height and magnetic field intensity. The application of this electromagnetic field to metallic particles is useful for creating a fixed structure to break gas bubbles, thereby intensifying the mass transfer process. Additionally, this method enhances the stability and efficiency of the fluidized bed, making it more effective for industrial applications.
