Hazards of Neodymium Magnets

Neodymium magnets are very useful but they are not without danger. So before operating the magnet, please read the hazards of neodymium magnets and remember that safety comes first!

Hazards of Neodymium Magnets Hazards of Neodymium Magnets

Risk of Cracking or Chipping

Neodymium magnets are super strong. If you bring two magnets close to each other, even small ones, they will attract, approach each other with great acceleration, and then slam together. This is the most common reason for breaking magnets. One or two magnets may shatter or break.

Because of the force exerted by the magnets, chips may fly into someone's eyes at a very high speed, so we recommend that you protect your eyes when you are handling multiple neodymium magnets. Chips and broken magnets can also be very sharp, so treat them with care like broken glass.

The Danger of Neodymium Magnets for Children 

When children are handling or playing with magnets, they should be supervised at all times. For small children who are likely to swallow magnets, magnets should be kept away from them at all times.

If multiple magnets are swallowed, they will attract each other through the intestinal wall, get stuck, and squeeze the digestive tract, causing severe swelling and even life-threatening injuries, requiring surgery. Therefore, always keep all neodymium magnets out of the reach of your children.

Crushing, Blood Blister, and Cuts

When larger magnets get close enough together, they can produce amazing amounts of energy. Fingers will be caught between them quickly, which can lead to blood blisters or cuts. So wear gloves when you are handling larger magnets and always handle them carefully. If the magnets are large enough ( more than 30 cm3+), they can crush fingers and break bones.

Magnetically Sensitive Items

The strength of neodymium magnets is ten times that of ordinary magnets. Keep a safe distance (at least 20cm) between the magnet and all objects that may be damaged by the magnetic force. Mechanical watches, cardiac pacemakers, CRT monitors and televisions, credit cards, floppy disks, and other magnetic storage media (such as videotapes) are all affected by powerful magnets.
