It will levitate above N52 high‑strength magnets due to flux pinning effect and can also be suspended underneath magnets.\u003c\/p\u003e\n\u003cp\u003eSuperconducting state lasts roughly 30 seconds. Insulation wrapping can greatly extend superconducting duration. Insulation materials need to be prepared by end‑user.\u003c\/p\u003e\n\u003ch3\u003eImportant Safety Notes\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eThis superconductor reacts with moisture, water and acid. Exposure above 600 °C will permanently destroy superconducting performance.\u003c\/li\u003e\n\u003cli\u003eContains toxic heavy‑metal elements including barium, copper and yttrium. Store securely. Use dedicated separate tools for demonstration. Never reuse experimental bowls or utensils for food. Wash hands thoroughly with soap after handling. Clean work surfaces and tools. Seek immediate medical help if swallowed.\u003c\/li\u003e\n\u003cli\u003eFrost will form on surface after each low‑temperature demonstration. Wipe frost completely. Store sealed away from light only after full drying.
