Following the innovative ideas of interdisciplinary practice teaching and design under the concept of "integration of art and technology this paper aims to carry out the innovative design practice of magnetic fluid demonstration instrument for popular science products based on the scientific research achievements of magnetic fluid, and explore and verify the interdisciplinary innovative design method of "integration of industry, learning, research and innovation". The research progress and development trend of interactive magnetic fluid popular science products are analyzed, and the design innovation path is explored. On the basis of demand and user experience, innovative design methods are designed to carry out product function innovation and interaction design. By controlling magnetotropic phase change effect of magnetic fluid, interactive demonstration design of music melody mapping, voice interactive mapping and facial expression interactive mapping are completed, real-time simulation technology of interaction is developed and realized, and a new interactive display mode of popular science products is formed. The innovative design elements and methods of interactive magnetic fluid popular science products were excavated, which effectively verified the practical ideas of design innovation under the concept of "integration of art and technology In conclusion, it has achieved the integration and innovation of science and art under the interdisciplinary teaching mode of comprehensive university, which can provide reference for similar teaching practice in the future.
