Pros as well as cons of Nd2Fe14B magnets.
Benefits
- They do not lose power, even over around 10 years – the reduction in power is only ~1% (according to tests),
- They retain their magnetic properties even under strong external field,
- Thanks to the glossy finish, the layer of Ni-Cu-Ni, gold-plated, or silver-plated gives an professional appearance,
- Magnetic induction on the surface of the magnet is very high,
- Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
- Possibility of exact forming and optimizing to defined requirements,
- Universal use in innovative solutions – they are utilized in magnetic memories, electric motors, advanced medical instruments, also complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which allows their use in small systems
Cons
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a strong case, which not only protects them against impacts but also raises their durability
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in creating nuts and complex forms in magnets, we propose using a housing - magnetic holder.
- Possible danger resulting from small fragments of magnets can be dangerous, in case of ingestion, which becomes key in the context of child safety. It is also worth noting that tiny parts of these devices are able to be problematic in diagnostics medical when they are in the body.
- Due to complex production process, their price exceeds standard values,
Lifting parameters
Maximum lifting force for a neodymium magnet – what contributes to it?
- using a sheet made of low-carbon steel, functioning as a circuit closing element
- whose thickness equals approx. 10 mm
- with an ground touching surface
- with zero gap (without paint)
- under vertical force vector (90-degree angle)
- in neutral thermal conditions
Lifting capacity in practice – influencing factors
- Distance (between the magnet and the plate), as even a very small distance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to paint, rust or debris).
- Loading method – catalog parameter refers to detachment vertically. When attempting to slide, the magnet exhibits significantly lower power (typically 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 converting into lifting capacity.
- Metal type – not every steel reacts the same. Alloy additives weaken the attraction effect.
- Plate texture – smooth surfaces ensure maximum contact, which improves force. Rough surfaces weaken the grip.
- Thermal conditions – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was performed on a smooth plate of suitable thickness, under perpendicular forces, in contrast under parallel forces the load capacity is reduced by as much as 75%. Additionally, even a slight gap between the magnet’s surface and the plate lowers the load capacity.
Safety rules for work with NdFeB magnets
Health Danger
Life threat: Neodymium magnets can deactivate pacemakers and defibrillators. Do not approach if you have medical devices.
Danger to the youngest
Strictly keep magnets out of reach of children. Ingestion danger is high, and the consequences of magnets connecting inside the body are tragic.
Nickel coating and allergies
Nickel alert: The Ni-Cu-Ni coating contains nickel. If an allergic reaction occurs, immediately stop handling magnets and use protective gear.
Do not drill into magnets
Mechanical processing of NdFeB material carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Impact on smartphones
Remember: rare earth magnets produce a field that interferes with sensitive sensors. Keep a safe distance from your phone, device, and navigation systems.
Material brittleness
Despite the nickel coating, neodymium is delicate and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.
Electronic devices
Equipment safety: Strong magnets can ruin payment cards and sensitive devices (heart implants, medical aids, timepieces).
Hand protection
Danger of trauma: The attraction force is so great that it can cause blood blisters, crushing, and even bone fractures. Protective gloves are recommended.
Maximum temperature
Avoid heat. Neodymium magnets are susceptible to heat. If you require operation above 80°C, ask us about HT versions (H, SH, UH).
Handling guide
Be careful. Rare earth magnets act from a distance and connect with massive power, often faster than you can move away.
