Ferrofluid Magnet
A mesmerising, physically honest ferrofluid dish toy. Drag a magnet beneath the dish and watch spikes rise on a real Rosensweig instability pattern along the field lines. Switch pole configurations (dipole, ring, opposing pair), tune field strength, mix in a coloured carrier fluid, and toggle a field-line overlay that explains the physics. Capture your best configuration as a shareable result card.
