Pros and cons of Nd2Fe14B magnets.
Benefits
- They have constant strength, and over around 10 years their attraction force decreases symbolically – ~1% (according to theory),
- Neodymium magnets remain remarkably resistant to loss of magnetic properties caused by magnetic disturbances,
- Thanks to the reflective finish, the surface of Ni-Cu-Ni, gold-plated, or silver gives an visually attractive appearance,
- The surface of neodymium magnets generates a powerful magnetic field – this is a distinguishing feature,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- In view of the potential of accurate shaping and adaptation to specialized projects, neodymium magnets can be created in a broad palette of shapes and sizes, which increases their versatility,
- Huge importance in high-tech industry – they are commonly used in hard drives, drive modules, advanced medical instruments, also other advanced devices.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Cons
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a steel housing, which not only protects them against impacts but also increases their durability
- When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their strength 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
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
- We recommend casing - magnetic mount, due to difficulties in creating threads inside the magnet and complex shapes.
- Possible danger to health – tiny shards of magnets pose a threat, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, small elements of these devices can disrupt the diagnostic process medical in case of swallowing.
- Due to expensive raw materials, their price is relatively high,
Pull force analysis
Best holding force of the magnet in ideal parameters – what contributes to it?
- on a block made of mild steel, optimally conducting the magnetic flux
- possessing a thickness of at least 10 mm to ensure full flux closure
- with an ground touching surface
- without any clearance between the magnet and steel
- during pulling in a direction perpendicular to the mounting surface
- at ambient temperature room level
Lifting capacity in practice – influencing factors
- Clearance – existence of foreign body (rust, dirt, air) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
- Metal type – different alloys attracts identically. Alloy additives worsen the attraction effect.
- Surface structure – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Unevenness acts like micro-gaps.
- Thermal environment – heating the magnet causes a temporary drop of force. Check the maximum operating temperature for a given model.
Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate reduces the load capacity.
Safe handling of NdFeB magnets
Danger to pacemakers
Individuals with a heart stimulator should maintain an absolute distance from magnets. The magnetism can interfere with the functioning of the life-saving device.
Safe distance
Very strong magnetic fields can destroy records on credit cards, HDDs, and other magnetic media. Keep a distance of at least 10 cm.
Demagnetization risk
Do not overheat. Neodymium magnets are susceptible to temperature. If you require operation above 80°C, look for HT versions (H, SH, UH).
Nickel allergy
Some people experience a hypersensitivity to Ni, which is the typical protective layer for NdFeB magnets. Extended handling can result in a rash. We strongly advise wear protective gloves.
Serious injuries
Risk of injury: The pulling power is so immense that it can cause hematomas, crushing, and even bone fractures. Protective gloves are recommended.
Beware of splinters
Watch out for shards. Magnets can explode upon violent connection, launching shards into the air. Eye protection is mandatory.
Powerful field
Before use, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Think ahead.
Dust is flammable
Combustion risk: Rare earth powder is explosive. Do not process magnets in home conditions as this may cause fire.
GPS and phone interference
Remember: rare earth magnets produce a field that disrupts precision electronics. Keep a separation from your phone, device, and navigation systems.
Keep away from children
Neodymium magnets are not suitable for play. Eating multiple magnets may result in them pinching intestinal walls, which constitutes a direct threat to life and requires immediate surgery.
