🧲 Magnetic Domains 2D

2D magnetic-domains simulator: a random-field Ising lattice with real domain-wall avalanches, an adjustable coercive field, and a live M-H hysteresis loop.

⚙ Under the hood

A 2D random-field Ising model of a ferromagnet: each grid cell flips when the local field from its neighbours plus the applied field crosses its own random coercive threshold, producing real domain-wall avalanches. Sweep the applied field automatically or by hand and watch the live magnetisation-vs-field hysteresis loop trace out.
