Pros and cons of Nd2Fe14B magnets.
Advantages
- They have stable power, and over around 10 years their performance decreases symbolically – ~1% (according to theory),
- They show high resistance to demagnetization induced by presence of other magnetic fields,
- Thanks to the elegant finish, the layer of Ni-Cu-Ni, gold-plated, or silver-plated gives an elegant appearance,
- Magnets exhibit impressive magnetic induction on the surface,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Possibility of accurate modeling as well as optimizing to specific needs,
- Significant place in modern technologies – they are commonly used in data components, electric drive systems, advanced medical instruments, as well as complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which enables their usage in compact constructions
Cons
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a steel housing, which not only secures them against impacts but also raises their durability
- 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 durability even at temperatures up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
- We suggest casing - magnetic holder, due to difficulties in producing nuts inside the magnet and complicated forms.
- Possible danger related to microscopic parts of magnets pose a threat, in case of ingestion, which is particularly important in the context of child safety. It is also worth noting that small elements of these magnets can disrupt the diagnostic process medical when they are in the body.
- With mass production the cost of neodymium magnets is a challenge,
Holding force characteristics
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- on a base made of structural steel, effectively closing the magnetic flux
- possessing a thickness of min. 10 mm to ensure full flux closure
- with a plane free of scratches
- without any insulating layer between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- in neutral thermal conditions
Practical aspects of lifting capacity – factors
- Space between magnet and steel – every millimeter of distance (caused e.g. by varnish or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
- Loading method – catalog parameter refers to detachment vertically. When applying parallel force, the magnet exhibits significantly lower power (often approx. 20-30% of maximum force).
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Material type – ideal substrate is high-permeability steel. Cast iron may attract less.
- Surface condition – smooth surfaces ensure maximum contact, which increases force. Rough surfaces reduce efficiency.
- Operating temperature – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under perpendicular forces, however under parallel forces the lifting capacity is smaller. Moreover, even a small distance between the magnet’s surface and the plate decreases the load capacity.
Safety rules for work with NdFeB magnets
No play value
Only for adults. Tiny parts can be swallowed, causing serious injuries. Store out of reach of kids and pets.
Threat to electronics
Do not bring magnets near a wallet, laptop, or TV. The magnetism can destroy these devices and wipe information from cards.
Heat sensitivity
Standard neodymium magnets (grade N) lose magnetization when the temperature surpasses 80°C. This process is irreversible.
Crushing risk
Risk of injury: The attraction force is so immense that it can cause blood blisters, pinching, and broken bones. Use thick gloves.
Precision electronics
Remember: neodymium magnets generate a field that confuses precision electronics. Keep a safe distance from your phone, device, and navigation systems.
Fire risk
Combustion risk: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this may cause fire.
Nickel coating and allergies
A percentage of the population have a hypersensitivity to Ni, which is the common plating for neodymium magnets. Frequent touching can result in a rash. It is best to use safety gloves.
Pacemakers
People with a heart stimulator should keep an large gap from magnets. The magnetic field can stop the operation of the life-saving device.
Immense force
Handle with care. Rare earth magnets attract from a distance and connect with massive power, often faster than you can move away.
Beware of splinters
Despite metallic appearance, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
