Advantages and disadvantages of neodymium magnets.
Pros
- They have constant strength, and over around ten years their attraction force decreases symbolically – ~1% (according to theory),
- They show high resistance to demagnetization induced by external disturbances,
- In other words, due to the aesthetic layer of gold, the element becomes visually attractive,
- Neodymium magnets deliver maximum magnetic induction on a contact point, which allows for strong attraction,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling action at temperatures reaching 230°C and above...
- Thanks to the ability of accurate shaping and customization to specialized projects, magnetic components can be created in a variety of forms and dimensions, which expands the range of possible applications,
- Fundamental importance in high-tech industry – they are commonly used in magnetic memories, electromotive mechanisms, advanced medical instruments, and other advanced devices.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- At very strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture
- We recommend casing - magnetic holder, due to difficulties in producing threads inside the magnet and complex forms.
- Potential hazard related to microscopic parts of magnets can be dangerous, if swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, tiny parts of these products are able to disrupt the diagnostic process medical after entering the body.
- With budget limitations the cost of neodymium magnets can be a barrier,
Lifting parameters
Maximum lifting capacity of the magnet – what contributes to it?
- with the use of a sheet made of special test steel, ensuring maximum field concentration
- possessing a thickness of at least 10 mm to avoid saturation
- with a plane perfectly flat
- without any clearance between the magnet and steel
- under perpendicular application of breakaway force (90-degree angle)
- in stable room temperature
What influences lifting capacity in practice
- Clearance – existence of any layer (paint, tape, gap) acts as an insulator, which reduces capacity rapidly (even by 50% at 0.5 mm).
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Steel thickness – too thin plate does not accept the full field, causing part of the flux to be wasted into the air.
- Metal type – different alloys attracts identically. Alloy additives weaken the attraction effect.
- Plate texture – ground elements guarantee perfect abutment, which improves force. Rough surfaces weaken the grip.
- Temperature influence – high temperature weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity was measured using a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.
Warnings
Serious injuries
Large magnets can break fingers instantly. Never place your hand between two strong magnets.
Fire risk
Fire warning: Neodymium dust is explosive. Do not process magnets in home conditions as this may cause fire.
Cards and drives
Intense magnetic fields can erase data on credit cards, hard drives, and other magnetic media. Keep a distance of at least 10 cm.
Handling rules
Handle magnets consciously. Their immense force can surprise even professionals. Be vigilant and do not underestimate their power.
Demagnetization risk
Avoid heat. NdFeB magnets are susceptible to temperature. If you require operation above 80°C, ask us about HT versions (H, SH, UH).
Fragile material
Watch out for shards. Magnets can explode upon violent connection, ejecting sharp fragments into the air. We recommend safety glasses.
GPS Danger
A powerful magnetic field negatively affects the functioning of compasses in phones and navigation systems. Do not bring magnets near a smartphone to prevent damaging the sensors.
Pacemakers
For implant holders: Strong magnetic fields disrupt medical devices. Keep at least 30 cm distance or ask another person to work with the magnets.
Warning for allergy sufferers
It is widely known that nickel (the usual finish) is a common allergen. For allergy sufferers, avoid touching magnets with bare hands and opt for coated magnets.
Adults only
Always keep magnets out of reach of children. Choking hazard is high, and the consequences of magnets connecting inside the body are tragic.
