Pros and cons of rare earth magnets.
Strengths
- They have unchanged lifting capacity, and over nearly ten years their performance decreases symbolically – ~1% (according to theory),
- They are noted for resistance to demagnetization induced by external magnetic fields,
- By applying a lustrous coating of gold, the element presents an modern look,
- They feature high magnetic induction at the operating surface, which increases their power,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling functioning at temperatures reaching 230°C and above...
- Considering the option of accurate shaping and adaptation to specialized needs, NdFeB magnets can be created in a broad palette of shapes and sizes, which expands the range of possible applications,
- Huge importance in future technologies – they are utilized in magnetic memories, drive modules, medical equipment, also other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which makes them useful in small systems
Limitations
- They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also increases its resistance to damage
- Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. 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 rust. Therefore when using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in producing threads and complicated forms in magnets, we recommend using cover - magnetic mount.
- Potential hazard to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child health protection. Furthermore, small components of these products are able to complicate diagnosis medical when they are in the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities
Lifting parameters
Detachment force of the magnet in optimal conditions – what it depends on?
- with the contact of a yoke made of special test steel, ensuring full magnetic saturation
- whose thickness equals approx. 10 mm
- with a surface free of scratches
- with total lack of distance (no paint)
- for force applied at a right angle (pull-off, not shear)
- in neutral thermal conditions
Lifting capacity in practice – influencing factors
- Distance – existence of any layer (paint, dirt, air) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Force direction – catalog parameter refers to pulling vertically. When slipping, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
- Plate thickness – too thin plate causes magnetic saturation, causing part of the flux to be lost into the air.
- Chemical composition of the base – mild steel attracts best. Alloy admixtures reduce magnetic permeability and holding force.
- Base smoothness – the more even the surface, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
- Thermal environment – heating the magnet causes a temporary drop of force. It is worth remembering the thermal limit for a given model.
Lifting capacity was measured using a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular detachment force, however under parallel forces the holding force is lower. Additionally, even a slight gap between the magnet and the plate decreases the holding force.
H&S for magnets
Keep away from electronics
A powerful magnetic field disrupts the functioning of compasses in phones and GPS navigation. Do not bring magnets near a device to prevent damaging the sensors.
Adults only
These products are not suitable for play. Accidental ingestion of several magnets may result in them attracting across intestines, which poses a severe health hazard and necessitates urgent medical intervention.
Immense force
Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Be predictive.
Danger to pacemakers
Life threat: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have medical devices.
Bone fractures
Large magnets can smash fingers in a fraction of a second. Do not put your hand between two attracting surfaces.
Electronic devices
Data protection: Strong magnets can damage data carriers and sensitive devices (pacemakers, hearing aids, timepieces).
Maximum temperature
Keep cool. NdFeB magnets are sensitive to temperature. If you require operation above 80°C, look for special high-temperature series (H, SH, UH).
Protective goggles
Despite the nickel coating, neodymium is brittle and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
Flammability
Fire warning: Rare earth powder is highly flammable. Do not process magnets without safety gear as this risks ignition.
Allergy Warning
It is widely known that nickel (standard magnet coating) is a strong allergen. For allergy sufferers, prevent touching magnets with bare hands and select coated magnets.
