CONCEPT

Normal-field instability in a precessing magnetic ferrofluid basin. Hexagonal conical spike lattices coalesce into serpentine labyrinthine chains under oblique rotating induction. 铁磁流体在旋转倾斜磁场中的法向场不稳定性:六角锥尖晶格与蛇形迷宫相的拓扑互变。

LORE

Below the dry Hele-Shaw terraces, the ash dips into an iron-rich hollow. 磁场在低处发生慢速进动,黏稠的黑液自发失稳,六角锥尖在倾斜拉力下被扯碎并融结为蠕动的蛇形迷宫。The basin neither drains nor evaporates; it only bristles and folds as the underground currents tilt.

JOURNAL

Modelling Rosensweig instability driven by an oblique precessing vector field $\mathbf{B}(t) = B_z \hat{z} + B_\perp (\cos \omega t \hat{x} + \sin \omega t \hat{y})$. 采用三波干涉项叠加局部非线性锐化来模拟尖锥点阵。当偏转角增大,三重对称性破缺,六角晶格自发坍缩为平行与分叉相间的条带迷宫。Density surged to 0.711 at peak striping where adjacent cones weld together along the field axis. Char distribution (`█`, `@` on apexes; `:`, `·` on meniscus floors) yields strong relief without display flicker.
