Users of neodymium magnets must take caution when handling them. First, for everyday magnet use, it is important to monitor magnets that might be found by children. If a magnet is swallowed, it can block respiratory and digestive tracts. If more than one magnet is swallowed, they might connect and serious issues such as completely closing off the esophagus. The simple fact of having the magnet inside the body can lead ot infection as well.
Additionally, because of the extremely high magnetism of larger NIB magnets, they can literally fly across a room if ferromagnetic metals are present. Any body part caught in the path of a magnet hurtling towards an object, or an object hurtling towards a magnet, is in danger of serious danger if the pieces do fly around. Getting a finger trapped between a magnet and a table top can be enough to shatter the finger bone. And if the magnet connects to something with enough momentum and force, it can shatter, firing dangerous shrapnel that can puncture skin and bones in many directions. It is important to know what’s in your pockets and what type of equipment is present when handling these magnets.
