Strengths and weaknesses of Nd2Fe14B magnets.
Pros
- Their magnetic field is maintained, and after approximately ten years it drops only by ~1% (theoretically),
- Neodymium magnets remain highly resistant to loss of magnetic properties caused by external interference,
- A magnet with a shiny silver surface has better aesthetics,
- They are known for high magnetic induction at the operating surface, which affects their effectiveness,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling operation at temperatures reaching 230°C and above...
- Considering the possibility of free molding and customization to specialized requirements, magnetic components can be produced in a broad palette of geometric configurations, which expands the range of possible applications,
- Key role in advanced technology sectors – they are utilized in hard drives, drive modules, precision medical tools, and technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which makes them useful in miniature devices
Cons
- To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop 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 very resistant to heat
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
- Due to limitations in realizing threads and complicated forms in magnets, we propose using a housing - magnetic mechanism.
- Potential hazard related to microscopic parts of magnets pose a threat, if swallowed, which becomes key in the context of child health protection. It is also worth noting that small elements of these devices can be problematic in diagnostics medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Optimal lifting capacity of a neodymium magnet – what it depends on?
- on a plate made of mild steel, effectively closing the magnetic field
- possessing a thickness of minimum 10 mm to avoid saturation
- characterized by even structure
- under conditions of ideal adhesion (metal-to-metal)
- under vertical force vector (90-degree angle)
- in neutral thermal conditions
Determinants of lifting force in real conditions
- Gap between magnet and steel – every millimeter of separation (caused e.g. by varnish or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Force direction – catalog parameter refers to detachment vertically. When slipping, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
- Metal type – different alloys reacts the same. High carbon content worsen the interaction with the magnet.
- Base smoothness – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Roughness creates an air distance.
- Temperature – temperature increase results in weakening of force. It is worth remembering 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, in contrast under parallel forces the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate decreases the load capacity.
Safety rules for work with neodymium magnets
Life threat
Life threat: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have electronic implants.
Protect data
Do not bring magnets near a wallet, laptop, or screen. The magnetism can destroy these devices and wipe information from cards.
Hand protection
Large magnets can break fingers in a fraction of a second. Never place your hand between two attracting surfaces.
This is not a toy
Absolutely store magnets away from children. Risk of swallowing is significant, and the consequences of magnets connecting inside the body are tragic.
Warning for allergy sufferers
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If an allergic reaction appears, immediately stop handling magnets and wear gloves.
Beware of splinters
Despite the nickel coating, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Caution required
Use magnets with awareness. Their powerful strength can shock even professionals. Stay alert and do not underestimate their power.
GPS Danger
GPS units and mobile phones are highly susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can ruin the internal compass in your phone.
Flammability
Dust produced during machining of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
Demagnetization risk
Keep cool. Neodymium magnets are susceptible to heat. If you need resistance above 80°C, look for special high-temperature series (H, SH, UH).
