摘要：
In the condition of certain electromagnetic levitation coil and spherical sample, according to the expressions of levitation force and absorbed power in magnetic field, the relationship between levitation force, absorbed power and high frequency power supply frequency is established in this paper. In addition, the effect of the power supply frequency on the levitation force of the coil and the absorbed power of the sample is analyzed, and the general rules of frequency parameter selection are confirmed. Finally, a guiding role in the frequency selection of high frequency power supply in electromagnetic levitation melting is played.
