Sound artist Christina Kubisch describes how she discovered electromagnetic induction, the phenomenon at the core of her work Electrical Walks San Francisco (2017), created for SFMOMA’s exhibition Soundtracks In this participatory piece, museumgoers don hypersensitive headsets that allow them to experience magnetic fields from electrical devices as sound — and in doing so to compose their own live soundtrack as they explore the urban area around the museum.
