考虑了弹性磁链的模型。通过对粘性流体中磁力和弹性力作用下杆体形状动力学的数值模拟，表明可以形成具有“U”字形特征的亚稳态形状(发夹)。依赖于杆的初始摄动，在中间阶段形成了具有“S”特征的长寿命形状，最后松弛到与直杆相对应的整体能量极小值。该模型的进一步扩展将包括杆的远处部分之间的远程磁相互作用。
The model of an elastic magnetic chain is considered. By numerical simulation of the dynamics of rod shapes acted on by magnetic and elastic forces in viscous fluid, it is shown that the characteristic 'U'-like metastable shapes (hairpins) can be formed. The characteristic 'S'-like long-living shapes are formed at intermediate stages, depending on the initial perturbation of the rod, and finally relax to the global energy minima corresponding to the straight rod. Further extensions of the model will include long-range magnetic interactions between distant parts of a rod.
