The Magnetic Primitive Library: A Platform for Designing Shape-Changing Interactions

This demonstration introduces the Magnetic Primitive Library (MPL) as a platform for hands-on exploration of programmable magnetic materials in interaction design. The MPL consists of a collection of magnetically actuated structures, each documented through domain configurations, fabrication guides, and visual notations. These primitives enable designers to engage with dynamic material behaviors by folding, programming, and activating silicone composites embedded with neodymium powder. We present the MPL as a platform for playful, hands-on material interaction, combining research-through-design with interdisciplinary material science. Through developing and demonstrating the library, we reflect on how the MPL fosters aesthetic ambiguity, curiosity, and material literacy, supporting designers in prototyping shape-changing interactions beyond functional outcomes.
