Advantages and disadvantages of neodymium magnets.
Advantages
- They retain full power for almost ten years – the loss is just ~1% (according to analyses),
- Magnets perfectly defend themselves against loss of magnetization caused by external fields,
- By using a smooth layer of gold, the element has an aesthetic look,
- Magnetic induction on the top side of the magnet is impressive,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to flexibility in forming and the capacity to adapt to individual projects,
- Versatile presence in high-tech industry – they find application in hard drives, electromotive mechanisms, medical equipment, also complex engineering applications.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Weaknesses
- To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
- Neodymium magnets decrease their power 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 during using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
- We suggest a housing - magnetic mechanism, due to difficulties in realizing threads inside the magnet and complicated forms.
- Potential hazard resulting from small fragments of magnets can be dangerous, in case of ingestion, which becomes key in the context of child safety. Additionally, small elements of these magnets can be problematic in diagnostics medical when they are in the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Holding force characteristics
Magnetic strength at its maximum – what affects it?
- on a block made of structural steel, perfectly concentrating the magnetic flux
- whose thickness equals approx. 10 mm
- with a surface cleaned and smooth
- under conditions of ideal adhesion (surface-to-surface)
- under vertical application of breakaway force (90-degree angle)
- in neutral thermal conditions
Lifting capacity in real conditions – factors
- Distance (betwixt the magnet and the metal), as even a very small distance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to paint, rust or debris).
- Force direction – catalog parameter refers to pulling vertically. When attempting to slide, the magnet exhibits significantly lower power (typically approx. 20-30% of maximum force).
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
- Metal type – different alloys reacts the same. High carbon content weaken the interaction with the magnet.
- Surface finish – ideal contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
- Temperature – temperature increase results in weakening of induction. Check the maximum operating temperature for a given model.
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under perpendicular forces, however under attempts to slide the magnet the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate reduces the lifting capacity.
Safe handling of neodymium magnets
Threat to navigation
A powerful magnetic field interferes with the operation of magnetometers in smartphones and GPS navigation. Maintain magnets close to a smartphone to prevent breaking the sensors.
Magnetic media
Device Safety: Neodymium magnets can damage payment cards and delicate electronics (heart implants, medical aids, mechanical watches).
Do not underestimate power
Before use, check safety instructions. Uncontrolled attraction can break the magnet or hurt your hand. Think ahead.
Swallowing risk
Product intended for adults. Small elements pose a choking risk, leading to severe trauma. Store away from children and animals.
Metal Allergy
Medical facts indicate that the nickel plating (standard magnet coating) is a potent allergen. If you have an allergy, refrain from direct skin contact and select encased magnets.
Implant safety
People with a heart stimulator should keep an large gap from magnets. The magnetism can interfere with the operation of the life-saving device.
Crushing force
Protect your hands. Two large magnets will snap together instantly with a force of several hundred kilograms, crushing anything in their path. Be careful!
Thermal limits
Do not overheat. NdFeB magnets are sensitive to temperature. If you require resistance above 80°C, inquire about HT versions (H, SH, UH).
Material brittleness
NdFeB magnets are ceramic materials, meaning they are prone to chipping. Clashing of two magnets will cause them cracking into shards.
Combustion hazard
Mechanical processing of NdFeB material poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
