Flip spins by hand
Tap or click any spin to flip it and watch its neighbors respond, mimicking nearest‑neighbor coupling in the Ising model.
Interact with a lattice of spins (+1 / −1) and see how magnetic domains form as you tweak temperature and external fields.
Explore the playground with intuitive controls and instant feedback.
Tap or click any spin to flip it and watch its neighbors respond, mimicking nearest‑neighbor coupling in the Ising model.
The net magnetization (M) updates in real time, giving you an immediate sense of order versus disorder.
Adjust thermal noise and external magnetic field to drive phase transitions and observe critical behavior.
Three simple steps to see emergent order from microscopic randomness.
Raise the temperature past the critical point to dissolve magnetic domains and maximize entropy.
Flip individual spins; nearest‑neighbor coupling causes clusters to grow or shrink.
Lower the temperature to lock in aligned domains, observing spontaneous symmetry breaking.

Quick answers to common curiosities.
The Ising model is a mathematical model of ferromagnetism in statistical mechanics. It consists of discrete variables called spins that can be in one of two states (+1 or −1). The spins are arranged on a lattice, allowing each spin to interact with its nearest neighbors. The model captures phase transitions and emergent magnetic order.
No prior physics knowledge is required. The playground is designed to be intuitive: you can click spins, adjust temperature, and watch the magnetization change in real time. Helpful tooltips guide you through the concepts.
Export functionality is available in the Researcher and Institution tiers. You can download the current spin configuration as a CSV or PNG image for further analysis or sharing.
Yes. The layout adapts to any screen size, and the spin lattice grid switches from 12 columns on desktop to 6 columns on touch devices, ensuring comfortable interaction.
Absolutely. The Student tier offers full access to the core interactive lattice, temperature controls, and live magnetization readout at no cost, forever.
Dive into the Ising lattice, explore phase transitions, and watch order arise from noise.
