MEISSNER EFFECT — SUPERCONDUCTOR LEVITATION FIELD

VISUAL STYLE: The Meissner effect made visible — the complete expulsion of magnetic field from the interior of a superconductor as it transitions to the superconducting state. A magnet levitates above a superconductor because the superconductor refuses to allow magnetic field lines to pass through it — expelling them completely, creating a mirror image field that pushes the magnet up. Physics that looks like magic, rendered with physical accuracy and visual beauty.

COLOUR PALETTE: Deep black as the ground. The superconductor surface in a specific deep, cool blue-grey — the colour of extreme cold, of liquid nitrogen temperature. Magnetic field lines in vivid electric blue — precise, geometric arcs. Outside the superconductor they curve normally between poles; at the superconductor surface they are perfectly expelled — bent sharply away, unable to enter. The Meissner current flowing on the superconductor surface in bright, luminous gold — the surface current that creates the opposing field. The levitating magnet in vivid crimson — its field lines in hot red-orange, interacting with the blue expulsion field at the boundary.

THE EXPELLED FIELD: The defining visual — magnetic field lines that would normally pass straight through a material are bent sharply at the superconductor surface and flow around it instead. The field is perfectly excluded from the interior. The inside of the superconductor is a region of zero magnetic field — shown as absolute black within the blue-grey material.

FLUX PINNING: In type-II superconductors, magnetic flux penetrates in discrete quantised tubes — flux vortices — shown as precise bright blue lines threading through the material at regular intervals, each carrying exactly one flux quantum.

LEVITATION GEOMETRY: The magnet floating above the superconductor — the gap between them sustained by the balance between magnetic attraction and the repulsion of the Meissner effect. The field geometry in the gap is shown in precise detail.

MOVEMENT: The magnet can be set spinning — it continues indefinitely, frictionlessly, above the superconductor surface.
