About this collection

Maxwell’s equations unite electricity and magnetism into one force and show that light is an electromagnetic wave. The Spark Herald and Magnetron Twins personify electromagnetism and magnetic dipoles in pixel art: opposite poles attract, like poles repel. Unisex pixel-art physics tees and hoodies (sizes S–5XL), plus stickers and sticker sheets.

Every electromagnetism design here is built on a real effect: Faraday's induction, Lenz's law pushing back on a falling magnet, charged particles circling in a magnetic field, and polarisers that filter light. Each product page lists the equation and sources.
