在第二个固定球体存在的情况下，研究一个磁球的二维运动为探索磁体-磁体相互作用、惯性、摩擦和丰富的非线性动力学行为提供了一个方便的场所。这些研究利用了这些磁相互作用与两个等效点偶极子之间相互作用的等效性。我们表明，磁体-磁体摩擦在磁球接触时起作用，台面摩擦在大球体分离时起作用，涡流总是可以忽略不计。基于web的仿真和可视化软件，称为MagPhyx，是为教育、探索和发现提供的。
Studies of the two-dimensional motion of a magnet sphere in the presence of a second, fixed sphere provide a convenient venue for exploring magnet-magnet interactions, inertia, friction, and rich nonlinear dynamical behavior. These studies exploit the equivalence of these magnetic interactions to the interactions between two equivalent point dipoles. We show that magnet-magnet friction plays a role when magnet spheres are in contact, table friction plays a role at large sphere separations, and eddy currents are always negligible. Web-based simulation and visualization software, called MagPhyx, is provided for education, exploration, and discovery.
