Advantages as well as disadvantages of Nd2Fe14B magnets.
Pros
- They have constant strength, and over nearly ten years their attraction force decreases symbolically – ~1% (in testing),
- They maintain their magnetic properties even under strong external field,
- A magnet with a shiny gold surface has an effective appearance,
- Magnets exhibit huge magnetic induction on the active area,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- Thanks to modularity in forming and the ability to customize to complex applications,
- Key role in advanced technology sectors – they find application in data components, motor assemblies, precision medical tools, as well as industrial machines.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Cons
- Brittleness is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a steel housing, which not only secures them against impacts but also raises their durability
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 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 resistant to moisture, when using outdoors
- We recommend casing - magnetic mount, due to difficulties in creating nuts inside the magnet and complicated shapes.
- Health risk related to microscopic parts of magnets can be dangerous, if swallowed, which becomes key in the context of child health protection. Additionally, small elements of these magnets are able to complicate diagnosis medical after entering the body.
- Due to neodymium price, their price is relatively high,
Pull force analysis
Detachment force of the magnet in optimal conditions – what it depends on?
- on a block made of mild steel, effectively closing the magnetic field
- possessing a massiveness of min. 10 mm to ensure full flux closure
- characterized by lack of roughness
- with direct contact (without impurities)
- under vertical force vector (90-degree angle)
- at room temperature
What influences lifting capacity in practice
- Gap (between the magnet and the metal), because 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, corrosion or dirt).
- Loading method – catalog parameter refers to pulling vertically. When applying parallel force, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
- Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
- Metal type – not every steel attracts identically. High carbon content worsen the attraction effect.
- Surface quality – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Unevenness acts like micro-gaps.
- Operating temperature – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).
Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under parallel forces the holding force is lower. Moreover, even a small distance between the magnet’s surface and the plate decreases the holding force.
Precautions when working with NdFeB magnets
Safe distance
Intense magnetic fields can corrupt files on payment cards, hard drives, and other magnetic media. Keep a distance of min. 10 cm.
Do not give to children
These products are not suitable for play. Swallowing multiple magnets may result in them connecting inside the digestive tract, which poses a severe health hazard and necessitates urgent medical intervention.
Keep away from electronics
Remember: rare earth magnets generate a field that confuses precision electronics. Keep a separation from your mobile, tablet, and GPS.
Immense force
Use magnets consciously. Their immense force can shock even experienced users. Plan your moves and do not underestimate their force.
Allergy Warning
Studies show that nickel (standard magnet coating) is a potent allergen. If you have an allergy, prevent touching magnets with bare hands and select coated magnets.
Pacemakers
Patients with a ICD should keep an large gap from magnets. The magnetism can disrupt the functioning of the life-saving device.
Magnets are brittle
Despite metallic appearance, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.
Power loss in heat
Keep cool. NdFeB magnets are susceptible to temperature. If you require operation above 80°C, ask us about HT versions (H, SH, UH).
Do not drill into magnets
Powder generated during machining of magnets is self-igniting. Do not drill into magnets unless you are an expert.
Physical harm
Pinching hazard: The attraction force is so immense that it can result in hematomas, crushing, and broken bones. Use thick gloves.
