Advantages and disadvantages of Nd2Fe14B magnets.
Benefits
- They have constant strength, and over around 10 years their attraction force decreases symbolically – ~1% (according to theory),
- They retain their magnetic properties even under strong external field,
- In other words, due to the smooth surface of gold, the element looks attractive,
- Magnets have huge magnetic induction on the outer side,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to modularity in forming and the capacity to customize to individual projects,
- Wide application in modern industrial fields – they find application in data components, electric drive systems, precision medical tools, as well as industrial machines.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Disadvantages
- To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
- When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in producing threads and complex forms in magnets, we propose using cover - magnetic mount.
- Health risk resulting from small fragments of magnets can be dangerous, if swallowed, which becomes key in the context of child health protection. It is also worth noting that small elements of these products can be problematic in diagnostics medical when they are in the body.
- With large orders the cost of neodymium magnets is economically unviable,
Holding force characteristics
Detachment force of the magnet in optimal conditions – what it depends on?
- with the contact of a sheet made of special test steel, guaranteeing maximum field concentration
- whose transverse dimension equals approx. 10 mm
- with a surface perfectly flat
- under conditions of gap-free contact (metal-to-metal)
- under perpendicular force direction (90-degree angle)
- at temperature approx. 20 degrees Celsius
Practical aspects of lifting capacity – factors
- Gap between surfaces – every millimeter of separation (caused e.g. by varnish or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
- Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Base massiveness – too thin steel does not accept the full field, causing part of the flux to be lost to the other side.
- Chemical composition of the base – mild steel gives the best results. Alloy steels lower magnetic properties and holding force.
- Surface quality – the more even the plate, the better the adhesion and higher the lifting capacity. Unevenness creates an air distance.
- Thermal conditions – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity testing was performed on a smooth plate of suitable thickness, under perpendicular forces, whereas under attempts to slide the magnet the holding force is lower. In addition, even a minimal clearance between the magnet’s surface and the plate lowers the load capacity.
Safety rules for work with neodymium magnets
Allergy Warning
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction happens, cease handling magnets and use protective gear.
Respect the power
Handle with care. Rare earth magnets attract from a distance and connect with massive power, often quicker than you can move away.
Do not overheat magnets
Monitor thermal conditions. Exposing the magnet to high heat will ruin its magnetic structure and pulling force.
Magnets are brittle
Despite the nickel coating, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Phone sensors
GPS units and smartphones are highly susceptible to magnetic fields. Direct contact with a strong magnet can ruin the internal compass in your phone.
Crushing force
Danger of trauma: The pulling power is so immense that it can cause blood blisters, crushing, and even bone fractures. Protective gloves are recommended.
Health Danger
People with a ICD must maintain an absolute distance from magnets. The magnetic field can stop the operation of the implant.
Threat to electronics
Very strong magnetic fields can destroy records on credit cards, hard drives, and other magnetic media. Keep a distance of at least 10 cm.
Flammability
Combustion risk: Neodymium dust is explosive. Avoid machining magnets in home conditions as this may cause fire.
Keep away from children
Product intended for adults. Small elements pose a choking risk, causing intestinal necrosis. Store out of reach of children and animals.
