Magnetic Domain Simulator

Move the magnet to see how the domains in the material change.

Note: Domains have a random probability of "flipping". It may take several passes of the magnet to align all the domains.

Portions of the code and design were developed with the assistance of OpenAI’s ChatGPT (GPT-5), September 2025.
