Magnetic Ferrofluid Spike — Iron Suspension in Field
167.06 €
Ferrofluid photographed in the presence of a neodymium magnet field — the iron-particle suspension forming the characteristic Rosensweig instability spike pattern against a mirrored surface.
Description
Ferrofluid — a colloidal suspension of iron oxide nanoparticles in a carrier fluid — responds to external magnetic fields by forming the Rosensweig instability: a series of sharp spikes whose height and spacing are determined by the balance between magnetic, gravitational, and surface tension forces. This image, made using a rare-earth neodymium magnet positioned below a mirrored dish containing the ferrofluid, captures the spike pattern at equilibrium — the spikes at maximum height and most defined geometry. Shot from a position 30 degrees above horizontal with a macro lens at 1:1 reproduction, the mirror surface creates a perfect downward reflection of each spike, the dual-spike geometry creating a landscape of inverted paired pyramids. Studio lighting was matched in colour temperature to the ferrofluid’s dark iridescent surface.
