Advantages and disadvantages of rare earth magnets.
Advantages
- Their strength is durable, and after approximately ten years it decreases only by ~1% (according to research),
- They retain their magnetic properties even under close interference source,
- Thanks to the shimmering finish, the surface of Ni-Cu-Ni, gold, or silver gives an professional appearance,
- They show high magnetic induction at the operating surface, which improves attraction properties,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Thanks to freedom in shaping and the ability to adapt to unusual requirements,
- Huge importance in modern technologies – they are utilized in mass storage devices, electric motors, medical equipment, and complex engineering applications.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Cons
- To avoid cracks under impact, we suggest using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
- Neodymium magnets lose their power 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 durability even at temperatures up to 230°C
- They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- We recommend cover - magnetic holder, due to difficulties in creating threads inside the magnet and complicated forms.
- Health risk to health – tiny shards of magnets pose a threat, in case of ingestion, which gains importance in the context of child health protection. Furthermore, small components of these magnets are able to complicate diagnosis medical in case of swallowing.
- Due to neodymium price, their price is higher than average,
Holding force characteristics
Optimal lifting capacity of a neodymium magnet – what affects it?
- using a plate made of mild steel, serving as a magnetic yoke
- with a thickness no less than 10 mm
- characterized by lack of roughness
- without any clearance between the magnet and steel
- for force acting at a right angle (pull-off, not shear)
- in neutral thermal conditions
Practical lifting capacity: influencing factors
- Air gap (between the magnet and the metal), because even a very small clearance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to paint, corrosion or dirt).
- Loading method – catalog parameter refers to pulling vertically. When attempting to slide, the magnet holds much less (typically approx. 20-30% of nominal force).
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
- Material type – the best choice is pure iron steel. Hardened steels may attract less.
- Base smoothness – the smoother and more polished the surface, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
- Heat – NdFeB sinters 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 optimal thickness, under a perpendicular pulling force, however under attempts to slide the magnet the load capacity is reduced by as much as fivefold. In addition, even a minimal clearance between the magnet and the plate lowers the lifting capacity.
Warnings
Compass and GPS
A powerful magnetic field interferes with the operation of magnetometers in phones and GPS navigation. Keep magnets near a device to prevent breaking the sensors.
This is not a toy
Neodymium magnets are not intended for children. Swallowing several magnets may result in them connecting inside the digestive tract, which poses a critical condition and necessitates immediate surgery.
Handling rules
Handle magnets with awareness. Their immense force can shock even professionals. Stay alert and do not underestimate their force.
Fire warning
Mechanical processing of NdFeB material poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
Thermal limits
Keep cool. Neodymium magnets are sensitive to heat. If you require operation above 80°C, ask us about HT versions (H, SH, UH).
Medical implants
Warning for patients: Strong magnetic fields affect medical devices. Keep at least 30 cm distance or request help to handle the magnets.
Bone fractures
Risk of injury: The attraction force is so immense that it can result in hematomas, crushing, and broken bones. Protective gloves are recommended.
Warning for allergy sufferers
A percentage of the population have a contact allergy to Ni, which is the common plating for NdFeB magnets. Frequent touching might lead to dermatitis. It is best to wear protective gloves.
Protective goggles
Beware of splinters. Magnets can explode upon violent connection, launching shards into the air. We recommend safety glasses.
Safe distance
Device Safety: Strong magnets can damage data carriers and delicate electronics (heart implants, hearing aids, timepieces).
