Strengths and weaknesses of neodymium magnets.
Pros
- They have constant strength, and over nearly 10 years their performance decreases symbolically – ~1% (according to theory),
- They have excellent resistance to magnetic field loss as a result of opposing magnetic fields,
- Thanks to the shimmering finish, the plating of Ni-Cu-Ni, gold, or silver-plated gives an modern appearance,
- They feature high magnetic induction at the operating surface, which improves attraction properties,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling operation at temperatures reaching 230°C and above...
- Due to the ability of free shaping and customization to specialized requirements, magnetic components can be manufactured in a variety of geometric configurations, which amplifies use scope,
- Significant place in modern industrial fields – they are utilized in data components, brushless drives, medical devices, and complex engineering applications.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Cons
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a strong case, which not only protects them against impacts but also increases their durability
- Neodymium magnets decrease 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 recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in producing threads and complicated shapes in magnets, we recommend using cover - magnetic mount.
- Possible danger resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child safety. It is also worth noting that small elements of these devices are able to be problematic in diagnostics medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what it depends on?
- on a plate made of structural steel, optimally conducting the magnetic field
- possessing a massiveness of min. 10 mm to ensure full flux closure
- with an polished touching surface
- with total lack of distance (no paint)
- during detachment in a direction perpendicular to the plane
- in stable room temperature
Determinants of lifting force in real conditions
- Gap (between the magnet and the plate), because even a tiny clearance (e.g. 0.5 mm) can cause a reduction in lifting capacity by up to 50% (this also applies to paint, rust or dirt).
- Loading method – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet exhibits significantly lower power (typically approx. 20-30% of maximum force).
- Plate thickness – too thin steel causes magnetic saturation, causing part of the power to be lost to the other side.
- Chemical composition of the base – low-carbon steel gives the best results. Alloy steels decrease magnetic properties and lifting capacity.
- Surface structure – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Unevenness creates an air distance.
- Temperature influence – high temperature weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, in contrast under shearing force the load capacity is reduced by as much as fivefold. Additionally, even a slight gap between the magnet’s surface and the plate decreases the load capacity.
H&S for magnets
Protect data
Do not bring magnets close to a wallet, laptop, or screen. The magnetism can permanently damage these devices and erase data from cards.
Heat sensitivity
Avoid heat. NdFeB magnets are susceptible to heat. If you require resistance above 80°C, look for special high-temperature series (H, SH, UH).
Fragile material
NdFeB magnets are ceramic materials, meaning they are very brittle. Clashing of two magnets leads to them breaking into small pieces.
Crushing risk
Big blocks can crush fingers instantly. Never put your hand betwixt two attracting surfaces.
This is not a toy
Product intended for adults. Small elements can be swallowed, causing serious injuries. Keep out of reach of kids and pets.
Nickel coating and allergies
It is widely known that nickel (standard magnet coating) is a potent allergen. For allergy sufferers, avoid touching magnets with bare hands and select versions in plastic housing.
Implant safety
People with a pacemaker have to maintain an safe separation from magnets. The magnetism can interfere with the operation of the life-saving device.
Fire risk
Dust created during grinding of magnets is combustible. Avoid drilling into magnets unless you are an expert.
GPS Danger
Remember: neodymium magnets produce a field that interferes with sensitive sensors. Maintain a separation from your phone, tablet, and GPS.
Do not underestimate power
Handle magnets consciously. Their huge power can surprise even professionals. Be vigilant and do not underestimate their force.
