Safety is really an important consideration when working with large and small magnets, here are some key safety considerations regarding large and small magnets.
Safety Precautions for Large(big) Magnets:
Large magnets are usually very heavy and should be moved with extreme care to ensure adequate support to prevent tipping or slipping. The suction force of large magnets is very strong and may cause pinched fingers or other body parts or even cause objects to splash. Large magnets produce a much wider range of magnetic fields that may affect nearby electronic devices, credit cards, watches, and other items. When installing or securing large magnets, make sure they are properly mounted to the structure and can withstand the weight and suction of the magnet. Appropriate personal protective equipment (PPE), such as gloves and safety glasses, may be required when handling large magnets. Use proper shielding and packaging when transporting large magnets, and isolate objects as thickly as possible to prevent accidental adsorption.

Safety precautions for small magnets:
Small magnets are easily swallowed by children, and if multiple magnets are swallowed, they may attract each other inside the body, causing serious health problems. Although smaller, powerful magnets (such as neodymium magnets) can still generate enough force to pinch a finger or other body part. Even small magnets may affect nearby sophisticated electronic equipment. Even small magnets may pinch skin when they attract each other.
General Safety Advice:
When handling magnets, especially when they are in close proximity, take care to avoid their sudden attraction.
Ensure that operators are aware of the potential hazards of magnets and the proper way to handle them.
Avoid using strong magnets near medical equipment and precision instruments.
Following these guidelines can greatly reduce the likelihood of accidents when using magnets.
