Advantages as well as disadvantages of neodymium magnets.
Strengths
- They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (according to literature),
- They feature excellent resistance to magnetism drop as a result of external magnetic sources,
- The use of an metallic coating of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- The surface of neodymium magnets generates a maximum magnetic field – this is a key feature,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Thanks to versatility in forming and the ability to customize to complex applications,
- Significant place in high-tech industry – they are utilized in mass storage devices, drive modules, precision medical tools, and multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which allows their use in compact constructions
Cons
- To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
- Neodymium magnets decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- We recommend cover - magnetic holder, due to difficulties in realizing threads 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. Furthermore, tiny parts of these products can disrupt the diagnostic process medical after entering the body.
- Due to expensive raw materials, their price is relatively high,
Holding force characteristics
Maximum lifting capacity of the magnet – what contributes to it?
- on a block made of structural steel, optimally conducting the magnetic flux
- possessing a massiveness of minimum 10 mm to avoid saturation
- characterized by even structure
- under conditions of ideal adhesion (metal-to-metal)
- under perpendicular force direction (90-degree angle)
- in neutral thermal conditions
Magnet lifting force in use – key factors
- Distance – the presence of foreign body (rust, dirt, gap) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Steel grade – ideal substrate is pure iron steel. Stainless steels may attract less.
- Surface quality – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Roughness acts like micro-gaps.
- Thermal conditions – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate decreases the lifting capacity.
Safety rules for work with NdFeB magnets
Medical implants
Life threat: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.
Dust is flammable
Powder produced during cutting of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Crushing risk
Large magnets can crush fingers in a fraction of a second. Under no circumstances place your hand between two attracting surfaces.
Do not overheat magnets
Avoid heat. Neodymium magnets are sensitive to temperature. If you require resistance above 80°C, look for HT versions (H, SH, UH).
Respect the power
Before starting, read the rules. Uncontrolled attraction can destroy the magnet or hurt your hand. Be predictive.
Precision electronics
An intense magnetic field interferes with the functioning of magnetometers in smartphones and navigation systems. Do not bring magnets close to a smartphone to prevent damaging the sensors.
Warning for allergy sufferers
Medical facts indicate that the nickel plating (the usual finish) is a common allergen. For allergy sufferers, avoid touching magnets with bare hands or opt for coated magnets.
No play value
Product intended for adults. Tiny parts can be swallowed, leading to serious injuries. Store out of reach of children and animals.
Magnetic media
Do not bring magnets close to a wallet, computer, or TV. The magnetism can irreversibly ruin these devices and wipe information from cards.
Magnets are brittle
Despite metallic appearance, neodymium is brittle and cannot withstand shocks. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
