We modelled three cases : a pair of conductive magnets, a magnet above a conductive plate and a magnet submerged in conductive material. The main results are the analytical derivations.The files ErrorVsFrequency.pdf, torqueComparison.pdf, twoSpheresCurrentDensity.pdf and twoSpheresMomentValidation.pdf show the result of Comsol simulations used to validate the model and test its range of validity.The associated .txt files like ErrorVsFrequency.txt contain the raw data plotted and the .m files are the matlab scripts used for plotting.The files rotatingDipole03.gif and rotatingDipole04.gif are animations of the Comsol simulation of a dipole rotating above a thick, conductive plate.The files EddyCurrentsTest04validation_ErrorVsFrequency_FINAL_NoSol.mph and EddyCurrentsTest04validation_FINAL_NoSol.mph are the Comsol simulation scripts. To reduce the file size, they do not contain the converged solutions, but they can be reproduced by running the .mph scripts.

概述：本研究聚焦于磁偶极磁体在导体附近运动时，因导电材料中感应涡流而受到的作用力与力矩。我们构建了三类仿真场景：成对导电磁体、置于导电平板上方的磁体，以及浸没于导电介质中的磁体，并针对其建立了相应模型。本研究的核心成果为模型的解析推导结果。
