In today's era where digital education and maker learning are prevalent, the design of teaching tools is no longer limited to static displays but is moving toward interactivity, modularity, and creative expansion. Flexible magnetic materials—especially flexible magnets that can be cut, printed, and adhered—are gradually becoming indispensable media in the new generation of educational settings. These materials can be flexibly applied to puzzle teaching aids, display boards, and modular signage systems. Moreover, due to their ease of processing and cost-effectiveness, they widely support hands-on practice and creative activities in STEAM education (Science, Technology, Engineering, Arts, and Mathematics).

Permanent magnets, also known as lodestones, can be made from natural products or artificially made. A material that can take on magnetism, retain the magnetism once magnetized, and withstand an external magnetic field without becoming demagnetized, can make a permanent magnet.
