force, the inclusions inside the melt can migrate to outer very fast. Fig.2 Effect on motion behavior of inclusion particles under high frequency magnetic field 3 Simulation and experiments... of the magnetic intensity, the external force on a particle is larger, and so is the velocity of the particle. When they reach the edge, they are captured by the internal wall of the ceramic tube......
by saturating magnetic flux of the core. Key words: electromagnetic force; parameters of coil; impulse current; sheet  ...-magnetic coupled finite element model is established to simulate electromagnetic force. The weldment is used as an axisymmetric sheet in the model because the weldment area is much larger than the coil......

In this study, an improved dynamic model of a RBS considering different frictional force models is presented. A comparative......
because of the electromagnetic force produced by the interaction of the pulsed magnetic field and the melt. When the pulsed magnetic field B is imposed to the melt, an induction current I will be produced in the melt. As a result, an electromagnetic force is generated by the coupling between the induction current and the magnetic field, i.e. F=J×B. The electromagnetic force F can be decom- posed......

and the performance improvement of the levitation system. As we all known, the electromagnetic force is determined solely by the magnetic flux of the levitation clearances [9]. The relationship among the electromagnetic force, levitation gap and flux may be simple and clearer if the feedback of magnetic flux is adopted by the inner loop. In this way, the synthesis of the levitation system......
