Strengths and weaknesses of Nd2Fe14B magnets.
Pros
- Their magnetic field is maintained, and after around 10 years it drops only by ~1% (according to research),
- Magnets perfectly defend themselves against loss of magnetization caused by foreign field sources,
- A magnet with a shiny nickel surface is more attractive,
- Magnetic induction on the surface of the magnet is maximum,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to the option of accurate molding and customization to individualized projects, magnetic components can be modeled in a wide range of shapes and sizes, which increases their versatility,
- Universal use in innovative solutions – they serve a role in hard drives, electric drive systems, medical devices, and multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which makes them useful in compact constructions
Weaknesses
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also increases its resistance to damage
- Neodymium magnets decrease their power 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 waterproof magnets made of rubber, plastic or other material protecting against moisture
- We suggest cover - magnetic mechanism, due to difficulties in creating nuts inside the magnet and complex forms.
- Possible danger related to microscopic parts of magnets pose a threat, in case of ingestion, which becomes key in the aspect of protecting the youngest. Furthermore, tiny parts of these products can complicate diagnosis medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Maximum magnetic pulling force – what contributes to it?
- on a block made of mild steel, optimally conducting the magnetic field
- possessing a thickness of at least 10 mm to ensure full flux closure
- with an ideally smooth touching surface
- under conditions of no distance (metal-to-metal)
- for force applied at a right angle (pull-off, not shear)
- in neutral thermal conditions
Lifting capacity in real conditions – factors
- Gap between surfaces – every millimeter of distance (caused e.g. by veneer or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Loading method – declared lifting capacity refers to detachment vertically. When slipping, the magnet exhibits much less (typically approx. 20-30% of nominal force).
- Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Metal type – not every steel attracts identically. High carbon content weaken the interaction with the magnet.
- Surface quality – the more even the plate, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
- Temperature influence – hot environment weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the load capacity is reduced by as much as fivefold. In addition, even a small distance between the magnet’s surface and the plate lowers the holding force.
Safety rules for work with NdFeB magnets
Skin irritation risks
Nickel alert: The Ni-Cu-Ni coating contains nickel. If redness occurs, immediately stop handling magnets and use protective gear.
Demagnetization risk
Watch the temperature. Exposing the magnet above 80 degrees Celsius will ruin its properties and strength.
Swallowing risk
Neodymium magnets are not suitable for play. Swallowing several magnets can lead to them attracting across intestines, which poses a critical condition and requires urgent medical intervention.
Machining danger
Combustion risk: Rare earth powder is highly flammable. Do not process magnets in home conditions as this may cause fire.
Medical implants
Health Alert: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.
Handling rules
Before starting, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.
Safe distance
Powerful magnetic fields can destroy records on payment cards, HDDs, and other magnetic media. Maintain a gap of min. 10 cm.
Serious injuries
Pinching hazard: The attraction force is so great that it can cause hematomas, pinching, and broken bones. Use thick gloves.
Risk of cracking
Beware of splinters. Magnets can fracture upon uncontrolled impact, ejecting shards into the air. We recommend safety glasses.
Precision electronics
Be aware: rare earth magnets produce a field that interferes with precision electronics. Keep a separation from your mobile, device, and navigation systems.
