Against a sensible expectation that molecular mobility in fluids generally disrupts magnetic orderings that depend on intermolecular interactions, some molecular compounds with isolated electrons, which are called radicals, exhibit the increase of magnetic susceptibility in melting. Here we first propose a simple model to explain the thermomagnetic anomaly unique to fluids; the effect of the magnetic interactions in each of the contacts could be accumulated on each of the molecular spins as if the molecular motion amplified the first coordination number of each molecule hundredfold. The huge coordination number theoretically guarantees the retention of memory of interactions at equilibrium; molecules might be able to conserve the memory of molecular conformations, configurations, electric charges, energies as well as magnetic memory with each other.

热分子运动可以放大分子间的电磁相互作用。

明智的预期是，流体中的分子迁移通常会破坏依赖于分子间相互作用的磁有序性，某些具有孤立电子的分子化合物（称为自由基）在熔化时表现出磁化率的增加。在这里，我们首先提出一个简单的模型来解释流体特有的热磁异常。每个接触中的磁相互作用的影响可以累积在每个分子自旋上，就像分子运动将每个分子的第一配位数放大了数百倍一样。理论上，巨大的配位数保证了相互作用时记忆的平衡。分子可能能够保留分子构象，构型，电荷，
