Strong magnets can interfere with the operation of pacemakers.
Ordinary neodymium magnets only use one side of their metal stick magnetic field which means they are only using half of their available force. However, if adding a steel cup, the other pole of the magnet to be used that increases the strength of the magnet to much higher than that of a normal neodymium magnet. At the same time, the steel cup also protects the magnet from being damaged when frequently used, but also makes the other side magnetic weak.
Strong magnets could affect water meter, electric meter, gas meter and some equipment meters.
If the highest possible pulling force is needed, then cutting neodymium magnets are the answer to your magnet needs
Neodymium magnets are fragile, and can peel, crack or break if allowed to slam together.
The Traction Force will be influenced by many factors: the material’s material, effective contact area, the softness of the surface, to the direction of traction, temperatures, material type, thickness, flatness, friction levels , etc.), its quality (eg rust delivery), its size (thickness plus total area), etc.
The pulling force will maximize when one pulls vertical direction with surface magnets.
The big neodymium magnets are extremely strong, and must be handled with care to avoid injuries and damage to the magnets.Fingers and other body parts can get severely pinched between two attract magnets.It is easy broken, if it please be careful.
Strong magnets should be kept away from ironwork and some easily magnetized iron products, such as monitors, bank cards, computers, televisions.
Never place neodymium magnets near electronics
Strong magnet must keep away from children, If loving damaged please dispose of shards completely. They are still magnetized and will cause serious problems if swallowed by children.
Neodymium magnets will lose their magnetic properties if heated to 80 ° C / 176 ° F.
