Pros and cons of Nd2Fe14B magnets.
Strengths
- Their magnetic field remains stable, and after approximately ten years it drops only by ~1% (theoretically),
- They feature excellent resistance to magnetism drop when exposed to opposing magnetic fields,
- In other words, due to the reflective surface of gold, the element becomes visually attractive,
- The surface of neodymium magnets generates a maximum magnetic field – this is a distinguishing feature,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for action at temperatures approaching 230°C and above...
- Considering the potential of flexible molding and adaptation to individualized needs, magnetic components can be created in a broad palette of geometric configurations, which increases their versatility,
- Significant place in modern industrial fields – they are used in mass storage devices, motor assemblies, advanced medical instruments, also technologically advanced constructions.
- 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 housings. Such a solution secures the magnet and simultaneously improves its durability.
- When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
- Limited possibility of producing threads in the magnet and complex shapes - recommended is casing - magnetic holder.
- Health risk resulting from small fragments of magnets can be dangerous, in case of ingestion, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small components of these magnets can disrupt the diagnostic process medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Highest magnetic holding force – what it depends on?
- with the contact of a sheet made of special test steel, ensuring full magnetic saturation
- whose transverse dimension reaches at least 10 mm
- with a plane perfectly flat
- under conditions of no distance (surface-to-surface)
- during detachment in a direction perpendicular to the plane
- in neutral thermal conditions
What influences lifting capacity in practice
- Air gap (betwixt the magnet and the plate), since even a very small clearance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
- Angle of force application – maximum parameter is available only during perpendicular pulling. The resistance to sliding of the magnet along the plate is standardly several times smaller (approx. 1/5 of the lifting capacity).
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Steel type – low-carbon steel attracts best. Alloy steels lower magnetic permeability and holding force.
- Surface finish – full contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Heat – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).
Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under parallel forces the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate lowers the lifting capacity.
H&S for magnets
Caution required
Be careful. Neodymium magnets act from a distance and snap with massive power, often faster than you can move away.
Phone sensors
An intense magnetic field interferes with the operation of magnetometers in phones and GPS navigation. Keep magnets close to a device to avoid damaging the sensors.
Dust is flammable
Powder generated during machining of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Life threat
For implant holders: Strong magnetic fields affect medical devices. Keep minimum 30 cm distance or ask another person to handle the magnets.
Risk of cracking
Beware of splinters. Magnets can explode upon uncontrolled impact, ejecting shards into the air. Wear goggles.
Thermal limits
Avoid heat. NdFeB magnets are sensitive to heat. If you require resistance above 80°C, look for HT versions (H, SH, UH).
Allergic reactions
Nickel alert: The nickel-copper-nickel coating contains nickel. If redness happens, cease working with magnets and use protective gear.
No play value
Product intended for adults. Small elements pose a choking risk, causing serious injuries. Keep away from children and animals.
Electronic hazard
Powerful magnetic fields can destroy records on payment cards, HDDs, and storage devices. Stay away of at least 10 cm.
Hand protection
Danger of trauma: The attraction force is so immense that it can result in blood blisters, pinching, and broken bones. Protective gloves are recommended.
