โลโก้จากผงตะไบเหล็กในสนามแม่เหล็ก

Hyper-realistic macro and environmental photograph of the silhouette of [the logo from the reference image] formed entirely by fine iron filings reacting naturally to a magnetic field on a flat [matte black lab tray]. The logo retains its exact shape and proportions, with fine needle-like iron filings clustering densely along curved magnetic field lines, forming spiky ridges and raised clusters over strong magnetic poles, and softer, more dispersed alignments near the outer edges with natural randomness and scattered loose filings. A realistic science lab or classroom setting surrounds the tray, with human hands partially visible nearby holding a magnet beneath the surface. Directional overhead lighting casts delicate shadows from the raised, spiky filings and catches subtle metallic reflections on their edges. Top-down, slightly angled close-up view with shallow depth of field blurring notebooks and lab tools in the background. Atmosphere of curious discovery and tactile physics, with no text overlays.
