Advantages as well as disadvantages of rare earth magnets.
Pros
- They retain attractive force for almost ten years – the loss is just ~1% (in theory),
- Neodymium magnets are exceptionally resistant to loss of magnetic properties caused by external magnetic fields,
- The use of an aesthetic layer of noble metals (nickel, gold, silver) causes the element to present itself better,
- The surface of neodymium magnets generates a unique magnetic field – this is one of their assets,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Considering the ability of accurate molding and adaptation to specialized requirements, neodymium magnets can be produced in a variety of forms and dimensions, which amplifies use scope,
- Fundamental importance in future technologies – they are utilized in computer drives, motor assemblies, precision medical tools, and technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which makes them useful in small systems
Weaknesses
- At very strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets decrease their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- We suggest cover - magnetic holder, due to difficulties in creating nuts inside the magnet and complex forms.
- Potential hazard to health – tiny shards of magnets are risky, in case of ingestion, which becomes key in the aspect of protecting the youngest. Furthermore, tiny parts of these devices can be problematic in diagnostics medical when they are in the body.
- With mass production the cost of neodymium magnets is a challenge,
Lifting parameters
Maximum lifting capacity of the magnet – what affects it?
- on a plate made of structural steel, optimally conducting the magnetic flux
- possessing a thickness of at least 10 mm to avoid saturation
- with a plane cleaned and smooth
- without any insulating layer between the magnet and steel
- under perpendicular force direction (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
What influences lifting capacity in practice
- Gap between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
- Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Substrate thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Steel type – low-carbon steel attracts best. Higher carbon content decrease magnetic properties and lifting capacity.
- Plate texture – smooth surfaces guarantee perfect abutment, which improves field saturation. Uneven metal weaken the grip.
- Thermal conditions – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, 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 reduces the load capacity.
H&S for magnets
Cards and drives
Device Safety: Neodymium magnets can ruin data carriers and delicate electronics (pacemakers, hearing aids, timepieces).
Compass and GPS
An intense magnetic field disrupts the functioning of magnetometers in phones and navigation systems. Do not bring magnets near a device to avoid damaging the sensors.
Avoid contact if allergic
Nickel alert: The nickel-copper-nickel coating consists of nickel. If redness appears, cease working with magnets and wear gloves.
Machining danger
Fire warning: Rare earth powder is highly flammable. Do not process magnets in home conditions as this may cause fire.
Danger to the youngest
Product intended for adults. Tiny parts can be swallowed, leading to severe trauma. Store out of reach of children and animals.
Hand protection
Large magnets can crush fingers instantly. Never put your hand betwixt two attracting surfaces.
Implant safety
People with a heart stimulator should maintain an absolute distance from magnets. The magnetic field can interfere with the functioning of the life-saving device.
Magnet fragility
Despite the nickel coating, neodymium is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Demagnetization risk
Do not overheat. NdFeB magnets are susceptible to heat. If you require operation above 80°C, ask us about HT versions (H, SH, UH).
Conscious usage
Use magnets with awareness. Their immense force can surprise even experienced users. Be vigilant and respect their power.
