Strengths and weaknesses of neodymium magnets.
Advantages
- They do not lose magnetism, even after approximately 10 years – the decrease in lifting capacity is only ~1% (theoretically),
- Neodymium magnets are highly resistant to loss of magnetic properties caused by external interference,
- In other words, due to the aesthetic layer of gold, the element is aesthetically pleasing,
- Neodymium magnets ensure maximum magnetic induction on a small area, which allows for strong attraction,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for functioning at temperatures approaching 230°C and above...
- Considering the potential of precise forming and adaptation to unique requirements, NdFeB magnets can be created in a broad palette of geometric configurations, which expands the range of possible applications,
- Significant place in modern industrial fields – they are used in magnetic memories, electromotive mechanisms, advanced medical instruments, also multitasking production systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Weaknesses
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
- NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
- Due to limitations in creating nuts and complex shapes in magnets, we recommend using cover - magnetic mount.
- Health risk resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that tiny parts of these products can be problematic in diagnostics medical when they are in the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities
Pull force analysis
Maximum magnetic pulling force – what affects it?
- using a base made of high-permeability steel, serving as a circuit closing element
- possessing a massiveness of minimum 10 mm to ensure full flux closure
- with a plane cleaned and smooth
- under conditions of ideal adhesion (metal-to-metal)
- under axial application of breakaway force (90-degree angle)
- at standard ambient temperature
Magnet lifting force in use – key factors
- Distance (betwixt the magnet and the plate), because even a microscopic clearance (e.g. 0.5 mm) can cause a reduction in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
- Angle of force application – highest force is obtained only during perpendicular pulling. The resistance to sliding of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
- Substrate thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Material composition – not every steel attracts identically. Alloy additives worsen the attraction effect.
- Surface structure – the more even the plate, the better the adhesion and higher the lifting capacity. Unevenness creates an air distance.
- Thermal environment – heating the magnet causes a temporary drop of induction. Check the maximum operating temperature for a given model.
Lifting capacity was determined using a smooth steel plate of optimal thickness (min. 20 mm), under vertically applied force, in contrast under parallel forces the load capacity is reduced by as much as fivefold. Additionally, even a slight gap between the magnet’s surface and the plate decreases the load capacity.
Safety rules for work with NdFeB magnets
Keep away from computers
Intense magnetic fields can erase data on payment cards, hard drives, and other magnetic media. Stay away of min. 10 cm.
Allergy Warning
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If skin irritation occurs, immediately stop handling magnets and use protective gear.
Crushing risk
Big blocks can smash fingers instantly. Never place your hand between two attracting surfaces.
Danger to pacemakers
People with a ICD must maintain an absolute distance from magnets. The magnetism can stop the operation of the implant.
Danger to the youngest
These products are not suitable for play. Swallowing a few magnets may result in them attracting across intestines, which poses a severe health hazard and requires immediate surgery.
Eye protection
Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Fire risk
Fire warning: Rare earth powder is highly flammable. Do not process magnets without safety gear as this may cause fire.
GPS and phone interference
An intense magnetic field interferes with the operation of magnetometers in phones and GPS navigation. Maintain magnets close to a device to avoid damaging the sensors.
Caution required
Be careful. Rare earth magnets act from a long distance and connect with huge force, often faster than you can react.
Demagnetization risk
Watch the temperature. Heating the magnet to high heat will ruin its properties and strength.
