Data repository for the article "Magnetic levitation at low rotation frequencies using a on-axis magnetic field", which can be found here: arXiv: https://arxiv.org/abs/2502.04410 or https://doi.org/10.48550/arXiv.2502.04410These data are located on the repository at data.dtu.dk, with DOI:10.11583/DTU.28302251 and URL: https://doi.org/10.11583/DTU.28302251Overview:The file Videos.zip contains the videos showing levitation for the three experiments, "Horizontal displacement", "Vertical displacement" and "Tilt". The videos are in subfolders named after the geometrical parameter changed, e.g. "dx=3mm" under "Horizontal_displacement". Each video is named according to the geometrical parameters, the initial distance of the aluminium plate from the bottom of the rotating magnet (so with a reported distance 5 mm less than the center distance reported in the manuscript, as the rotor magnets have a size of 10 mm), the frequency of rotation of the rotor, and the experiment number, e.g. the video "3mm_70Hz_35mmAlu_Trimed_2.mp4" is for dx=3 mm, a rotor frequency of 70 Hz, with the aluminium plate 35 mm from the bottom of the rotor magnet and this is the second experiment conducted.The files "Levidist_list_Horizontal_displacement_exp.csv", "Levidist_list_Vertical_displacement_exp.csv" and "Levidist_list_Til_expt.csv" are CSV files based on processing of the experimental video files. The CSV files contains the Frequency in Hz, the geometrical parameter, the initial aluminum plate distance from the bottom of the rotor in mm, the determined levitation distance in m, the determined levitation time in s, a Boolean value indicating whether the levitation ended or not before the experiment was stopped - if this value is equal to 1, the value given in levitation time is simply a plotting value, and a Boolean always equal to one that indicates if the video was analyzed with machine learning.The files "Levidist_list_Horizontal_displacement_sim.csv", "Levdist_list_Vertical_displacement_sim.csv" and "Levidist_list_Til_simt.csv" are CSV files based on processing of the simulation results. The CSV files contains the Frequency in Hz, the geometrical parameter in mm, the Initial position in mm, the Levitation Distance in mm without dampening, and the Levitation Distance in mm with dampening.

数据集概览：压缩包Videos.zip包含三类实验的悬浮演示视频，分别为"Horizontal displacement"、"Vertical displacement"与"Tilt"实验。视频按修改的几何参数存储于对应子文件夹中，例如"Horizontal_displacement"目录下的"dx=3mm"文件夹。每个视频的命名规则为：几何参数、铝板与旋转磁体底部的初始间距（注：报告的间距较论文中记载的中心间距小5mm，因转子磁体尺寸为10mm）、转子旋转频率与实验序号。例如视频"3mm_70Hz_35mmAlu_Trimed_2.mp4"对应dx=3mm、转子旋转频率70Hz、铝板距转子磁体底部35mm，且为本次实验的第2组样本。

以下逗号分隔值（CSV, Comma-Separated Values）文件基于实验视频的处理结果生成："Levidist_list_Horizontal_displacement_exp.csv"、"Levidist_list_Vertical_displacement_exp.csv"与"Levidist_list_Til_expt.csv"。文件内包含以下字段：频率（单位：Hz）、几何参数、铝板距转子磁体底部的初始间距（单位：mm）、实测悬浮间距（单位：m）、实测悬浮时长（单位：s）、布尔标记（用于指示实验终止前悬浮是否失效：若该值为1，则给出的悬浮时长仅用于绘图），以及一个恒为1的布尔标记，用于标记该视频已通过机器学习完成分析。

以下CSV文件基于仿真结果的处理结果生成："Levidist_list_Horizontal_displacement_sim.csv"、"Levdist_list_Vertical_displacement_sim.csv"与"Levidist_list_Til_simt.csv"。文件内包含以下字段：频率（单位：Hz）、几何参数（单位：mm）、初始位置（单位：mm）、无阻尼悬浮间距（单位：mm）与带阻尼悬浮间距（单位：mm）。
