Modeling of Levitation Force for a Wireless-Moving-Levitating Light with Multiple Magnetic Fields
This paper presents the modeling of the levitation force for a wireless-moving-levitating light (WMLL) developed in the laboratory. The mechanical structure of the WMLL is first given. A control scheme, which is used to regulate the energized current for stable, quick, and accurate levitation of the levitating disk, is then presented. Furthermore, the model of the levitation force is theoretically derived based on the Ampere molecular current hypothesis and the Biot-Savart law. Additionally, a finite element analysis is performed to characterize the levitation force. Finally, the effectiveness of the model is verified through the experimental results.
