| Abstract: | Through analysing the magnetic stress tensor which exerts on the surface of particles, the reason of eliminating bubbles in the fluidized bed with a magnetic field is explained. An experimental research of removing bubbles in the fluidized bed with a magnetic field is carried out and it is shown that the magnetic field can not only check the bubbles and widen the range of the velocity of the particulate fluidization, but also eliminate the bubbles and change the aggregative fluidization into the particulate one. |
