Magnetic flux is the measure of a magnetic field passing through a given surface—visualized as looping field lines that flow continuously from one pole of a magnet to the other, never beginning and never ending. This poster translates that invisible phenomenon into physical form. At its center, "FLUX" is 3D modeled in Adobe Illustrator, its letterforms given volume and depth before being shaped into a toroidal C-form—itself a nod to the closed-loop nature of magnetic field lines. Spiraling around it, tiny text traces the contour of the shape—hand-drawn paths in Illustrator with type set directly on them, following the field's curvature like iron filings aligning to a magnet. The surrounding field line arrows, generated programmatically with p5.js, complete the picture, mapping the characteristic loops of flux around the form. The warm amber palette draws on historical scientific illustration, while the grid and scattered letterforms of "MAGNETIC" reinforce the sense of a diagram pulled from a physics textbook and pushed into motion. The piece sits at the intersection of typography, physics, and generative design—where a formula becomes a form.
