结合理论论证和数值模拟，我们证明了金属垫辊不稳定性可以发生在一个厘米级的设置与合理的值的磁场和电流和金属对，在室温下是液体。我们调查两种流体对：镓与汞（不混溶对）或镓与GaInSn共晶合金（混溶对）。
Combining theoretical arguments and numerical simulations, we demonstrate that the metal pad roll instability can occur in a centimeter-scale setup with reasonable values of the magnetic field and electrical current and with metal pairs that are liquid at room temperature. We investigate two fluid pairs: gallium with mercury (immiscible pair) or gallium with GaInSn eutectic alloy (miscible pair).
