Strengths as well as weaknesses of rare earth magnets.
Strengths
- Their magnetic field remains stable, and after around 10 years it drops only by ~1% (according to research),
- They possess excellent resistance to magnetism drop when exposed to external fields,
- In other words, due to the aesthetic finish of gold, the element is aesthetically pleasing,
- Magnetic induction on the working layer of the magnet turns out to be impressive,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to versatility in constructing and the ability to modify to specific needs,
- Significant place in innovative solutions – they serve a role in computer drives, electric motors, advanced medical instruments, and other advanced devices.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Disadvantages
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also improves 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 while using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Limited possibility of making threads in the magnet and complicated shapes - preferred is a housing - magnet mounting.
- Possible danger resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child safety. Additionally, tiny parts of these products can disrupt the diagnostic process medical in case of swallowing.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Pull force analysis
Maximum lifting force for a neodymium magnet – what contributes to it?
- using a plate made of low-carbon steel, functioning as a magnetic yoke
- possessing a massiveness of minimum 10 mm to ensure full flux closure
- with an polished contact surface
- with zero gap (without impurities)
- during detachment in a direction vertical to the plane
- at standard ambient temperature
Key elements affecting lifting force
- Distance (betwixt the magnet and the plate), because even a tiny distance (e.g. 0.5 mm) leads to a drastic drop in force by up to 50% (this also applies to paint, corrosion or debris).
- Angle of force application – maximum parameter is obtained only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is standardly several times lower (approx. 1/5 of the lifting capacity).
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
- Chemical composition of the base – mild steel gives the best results. Alloy steels reduce magnetic permeability and lifting capacity.
- Smoothness – ideal contact is possible only on polished steel. Any scratches and bumps create air cushions, reducing force.
- Operating temperature – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the holding force is lower. Moreover, even a slight gap between the magnet’s surface and the plate lowers the lifting capacity.
Warnings
Beware of splinters
Despite metallic appearance, neodymium is delicate and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
Impact on smartphones
A strong magnetic field negatively affects the operation of magnetometers in phones and GPS navigation. Keep magnets near a device to avoid damaging the sensors.
Do not give to children
Adult use only. Tiny parts can be swallowed, leading to intestinal necrosis. Keep away from children and animals.
Metal Allergy
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If an allergic reaction occurs, cease handling magnets and use protective gear.
Implant safety
Patients with a heart stimulator must maintain an absolute distance from magnets. The magnetic field can stop the operation of the life-saving device.
Do not drill into magnets
Dust created during grinding of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.
Maximum temperature
Standard neodymium magnets (N-type) lose magnetization when the temperature exceeds 80°C. Damage is permanent.
Finger safety
Big blocks can crush fingers instantly. Do not place your hand betwixt two attracting surfaces.
Protect data
Intense magnetic fields can corrupt files on payment cards, hard drives, and other magnetic media. Maintain a gap of at least 10 cm.
Handling rules
Handle with care. Neodymium magnets act from a long distance and snap with massive power, often faster than you can move away.
