This page presents test results from the National Consumer Affairs Center regarding neodymium magnets that broke when attached. The investigation examined a case where a fourth magnet (approximately 15mm diameter, 3mm thick) broke when attached to three already-adhered magnets. Testing revealed that breakage can occur regardless of the number or order of magnets attached, due to impact from strong magnetic force. The report advises consumers to avoid rapid attachment or dropping neodymium magnets, and to carefully handle broken pieces to prevent injury, disposing of them according to local regulations.
