Strengths and weaknesses of Nd2Fe14B magnets.
Advantages
- They retain magnetic properties for almost 10 years – the drop is just ~1% (according to analyses),
- Magnets effectively defend themselves against demagnetization caused by foreign field sources,
- In other words, due to the aesthetic layer of silver, the element becomes visually attractive,
- They show high magnetic induction at the operating surface, which affects their effectiveness,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling action at temperatures reaching 230°C and above...
- Thanks to versatility in designing and the capacity to modify to unusual requirements,
- Significant place in future technologies – they serve a role in computer drives, electric drive systems, medical devices, as well as industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which makes them useful in miniature devices
Cons
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a special holder, which not only secures them against impacts but also raises their durability
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- They rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Due to limitations in producing threads and complicated shapes in magnets, we recommend using casing - magnetic holder.
- Possible danger resulting from small fragments of magnets can be dangerous, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Furthermore, small elements of these magnets can complicate diagnosis medical when they are in the body.
- With budget limitations the cost of neodymium magnets can be a barrier,
Pull force analysis
Maximum magnetic pulling force – what it depends on?
- with the use of a yoke made of special test steel, guaranteeing full magnetic saturation
- possessing a thickness of minimum 10 mm to ensure full flux closure
- characterized by lack of roughness
- under conditions of gap-free contact (metal-to-metal)
- under vertical force vector (90-degree angle)
- at conditions approx. 20°C
Practical aspects of lifting capacity – factors
- Air gap (between the magnet and the metal), because even a microscopic clearance (e.g. 0.5 mm) results in a drastic drop in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
- Loading method – catalog parameter refers to detachment vertically. When applying parallel force, the magnet holds much less (typically approx. 20-30% of nominal force).
- Base massiveness – too thin plate does not close the flux, causing part of the power to be escaped into the air.
- Steel grade – ideal substrate is high-permeability steel. Stainless steels may have worse magnetic properties.
- Plate texture – ground elements ensure maximum contact, which improves force. Uneven metal weaken the grip.
- Operating temperature – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and in frost gain strength (up to a certain limit).
Lifting capacity was measured with the use of a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, however under shearing force the load capacity is reduced by as much as 5 times. In addition, even a small distance between the magnet and the plate reduces the lifting capacity.
Precautions when working with neodymium magnets
Allergy Warning
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If skin irritation appears, cease handling magnets and use protective gear.
Danger to the youngest
Always keep magnets away from children. Risk of swallowing is high, and the effects of magnets clamping inside the body are fatal.
Danger to pacemakers
Health Alert: Neodymium magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.
Heat sensitivity
Control the heat. Heating the magnet above 80 degrees Celsius will destroy its magnetic structure and strength.
Electronic hazard
Device Safety: Strong magnets can ruin data carriers and delicate electronics (pacemakers, medical aids, timepieces).
Precision electronics
Be aware: neodymium magnets produce a field that disrupts sensitive sensors. Maintain a separation from your mobile, tablet, and GPS.
Do not underestimate power
Handle magnets with awareness. Their immense force can shock even experienced users. Plan your moves and do not underestimate their power.
Combustion hazard
Powder produced during machining of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.
Physical harm
Protect your hands. Two powerful magnets will join immediately with a force of several hundred kilograms, crushing everything in their path. Be careful!
Beware of splinters
Despite metallic appearance, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
