磁懸浮裝置探究及相關參數之探討 The Exploration of Magnetic Levitation Devices and Discussion of Related Parameters
This study focuses on magnetic levitation, attempting to create a system using a single magnet and a copper plate that allows the magnet above the copper plate to levitate. The research observes and analyzes the levitation conditions and the orientation of the magnet above. During the process, we measured the resistance exerted by the copper plate on the magnet, as well as the relationship between the magnetic field strength above the copper plate and various parameters when the magnet below is connected to a rotating platform. This study primarily investigates the rotational speed of the platform and the thickness of the copper plate as variables, measuring and analyzing the movement radius, tilt angle, orientation, and levitation condition of the magnet above under different parameter combinations. Since current technology has not yet advanced to a point where the upper magnet can stably levitate, we defined a levitation coefficient to describe the state of magnetic levitation. Finally, we derived the relationship between the resistance caused by the copper plate, the speed of the magnet's movement, and the thickness of the copper plate, as well as the relationship between magnetic field strength and the distance from the center of the rotating platform in relation to the thickness of the copper plate or the rotational speed, and illustrated the levitation conditions of the upper magnet under different parameters using a phase diagram.
