Strengths and weaknesses of rare earth magnets.
Pros
- They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (in laboratory conditions),
- Magnets perfectly defend themselves against loss of magnetization caused by foreign field sources,
- In other words, due to the reflective finish of gold, the element gains a professional look,
- Neodymium magnets ensure maximum magnetic induction on a their surface, which allows for strong attraction,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling action at temperatures reaching 230°C and above...
- Thanks to freedom in constructing and the ability to customize to unusual requirements,
- Huge importance in innovative solutions – they are used in magnetic memories, drive modules, diagnostic systems, and other advanced devices.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Disadvantages
- To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution protects the magnet and simultaneously increases its 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 durability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- We recommend cover - magnetic mechanism, due to difficulties in producing threads inside the magnet and complicated shapes.
- Potential hazard to health – tiny shards of magnets can be dangerous, if swallowed, which is particularly important in the context of child health protection. Additionally, small components of these products are able to complicate diagnosis medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Maximum lifting force for a neodymium magnet – what it depends on?
- with the use of a yoke made of low-carbon steel, ensuring maximum field concentration
- whose thickness is min. 10 mm
- characterized by even structure
- with total lack of distance (no impurities)
- under axial force direction (90-degree angle)
- at conditions approx. 20°C
Determinants of lifting force in real conditions
- Space between surfaces – every millimeter of separation (caused e.g. by veneer or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
- Force direction – catalog parameter refers to pulling vertically. When slipping, the magnet exhibits much less (typically approx. 20-30% of nominal force).
- Substrate thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Material composition – not every steel attracts identically. High carbon content weaken the attraction effect.
- Surface finish – full contact is obtained only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
- Temperature influence – high temperature reduces pulling force. Too high temperature can permanently damage the magnet.
Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, in contrast under parallel forces the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate reduces the load capacity.
Precautions when working with NdFeB magnets
Skin irritation risks
It is widely known that the nickel plating (the usual finish) is a strong allergen. If your skin reacts to metals, refrain from touching magnets with bare hands or choose versions in plastic housing.
Bodily injuries
Big blocks can crush fingers in a fraction of a second. Under no circumstances put your hand between two attracting surfaces.
Threat to electronics
Equipment safety: Strong magnets can damage payment cards and delicate electronics (pacemakers, hearing aids, timepieces).
Magnets are brittle
Neodymium magnets are ceramic materials, which means they are fragile like glass. Collision of two magnets will cause them cracking into shards.
Keep away from electronics
A powerful magnetic field interferes with the functioning of compasses in smartphones and GPS navigation. Maintain magnets near a device to prevent damaging the sensors.
Health Danger
Patients with a ICD have to keep an safe separation from magnets. The magnetic field can stop the operation of the life-saving device.
Caution required
Use magnets with awareness. Their immense force can surprise even professionals. Plan your moves and respect their force.
Dust is flammable
Combustion risk: Neodymium dust is explosive. Avoid machining magnets in home conditions as this risks ignition.
Danger to the youngest
Product intended for adults. Small elements can be swallowed, causing intestinal necrosis. Keep out of reach of children and animals.
Power loss in heat
Keep cool. Neodymium magnets are susceptible to heat. If you require resistance above 80°C, look for special high-temperature series (H, SH, UH).
