Strengths as well as weaknesses of Nd2Fe14B magnets.
Benefits
- Their power is durable, and after around 10 years it drops only by ~1% (according to research),
- Magnets effectively resist against demagnetization caused by external fields,
- Thanks to the smooth finish, the layer of nickel, gold, or silver-plated gives an visually attractive appearance,
- They feature high magnetic induction at the operating surface, which increases their power,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for operation at temperatures approaching 230°C and above...
- Thanks to modularity in shaping and the capacity to customize to specific needs,
- Significant place in modern industrial fields – they are utilized in magnetic memories, electromotive mechanisms, advanced medical instruments, also modern systems.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Weaknesses
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a special holder, which not only secures them against impacts but also raises their durability
- Neodymium magnets lose 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
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
- We recommend cover - magnetic holder, due to difficulties in producing threads inside the magnet and complex forms.
- Potential hazard related to microscopic parts of magnets are risky, in case of ingestion, which gains importance in the context of child safety. Additionally, small components of these magnets are able to be problematic in diagnostics medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Best holding force of the magnet in ideal parameters – what it depends on?
- using a base made of mild steel, functioning as a magnetic yoke
- possessing a massiveness of at least 10 mm to ensure full flux closure
- characterized by lack of roughness
- with direct contact (no paint)
- under axial application of breakaway force (90-degree angle)
- at ambient temperature room level
Determinants of practical lifting force of a magnet
- Clearance – the presence of any layer (rust, dirt, air) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet exhibits significantly lower power (often approx. 20-30% of maximum force).
- Base massiveness – too thin steel does not accept the full field, causing part of the flux to be lost into the air.
- Metal type – different alloys reacts the same. High carbon content weaken the interaction with the magnet.
- Smoothness – full contact is possible only on polished steel. Rough texture create air cushions, reducing force.
- Heat – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and at low temperatures gain strength (up to a certain limit).
Lifting capacity was measured using a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, whereas under parallel forces the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate reduces the lifting capacity.
Safe handling of NdFeB magnets
Danger to pacemakers
People with a ICD should maintain an large gap from magnets. The magnetic field can disrupt the functioning of the implant.
GPS and phone interference
An intense magnetic field interferes with the operation of magnetometers in phones and GPS navigation. Keep magnets close to a smartphone to prevent breaking the sensors.
Demagnetization risk
Regular neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. The loss of strength is permanent.
Swallowing risk
Product intended for adults. Tiny parts can be swallowed, causing serious injuries. Keep out of reach of kids and pets.
Flammability
Powder produced during grinding of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Hand protection
Risk of injury: The pulling power is so immense that it can result in blood blisters, pinching, and even bone fractures. Use thick gloves.
Keep away from computers
Intense magnetic fields can corrupt files on credit cards, hard drives, and other magnetic media. Stay away of min. 10 cm.
Nickel coating and allergies
It is widely known that the nickel plating (standard magnet coating) is a potent allergen. For allergy sufferers, avoid touching magnets with bare hands and opt for encased magnets.
Fragile material
Despite the nickel coating, the material is delicate and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.
Respect the power
Use magnets with awareness. Their huge power can shock even professionals. Be vigilant and do not underestimate their force.
