Strengths as well as weaknesses of Nd2Fe14B magnets.
Strengths
- They retain attractive force for almost 10 years – the drop is just ~1% (based on simulations),
- They are noted for resistance to demagnetization induced by external disturbances,
- The use of an refined coating of noble metals (nickel, gold, silver) causes the element to present itself better,
- They show high magnetic induction at the operating surface, making them more effective,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, allowing for action at temperatures approaching 230°C and above...
- Thanks to modularity in shaping and the capacity to adapt to specific needs,
- Significant place in future technologies – they are commonly used in data components, motor assemblies, advanced medical instruments, and modern systems.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Disadvantages
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape as well as 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- We recommend a housing - magnetic holder, due to difficulties in producing nuts inside the magnet and complex shapes.
- Possible danger to health – tiny shards of magnets can be dangerous, if swallowed, which is particularly important in the context of child safety. Furthermore, tiny parts of these devices are able to be problematic in diagnostics medical when they are in the body.
- Due to neodymium price, their price is relatively high,
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what affects it?
- on a base made of structural steel, optimally conducting the magnetic flux
- whose thickness is min. 10 mm
- with a surface cleaned and smooth
- without any clearance between the magnet and steel
- under vertical force direction (90-degree angle)
- at room temperature
Lifting capacity in real conditions – factors
- Distance (betwixt the magnet and the plate), since even a tiny clearance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
- 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).
- Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet limits the attraction force (the magnet "punches through" it).
- Metal type – not every steel reacts the same. High carbon content worsen the attraction effect.
- Smoothness – full contact is obtained only on smooth steel. Rough texture create air cushions, reducing force.
- Thermal conditions – NdFeB sinters have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity was assessed with the use of a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, in contrast under shearing force the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet and the plate reduces the lifting capacity.
Safe handling of neodymium magnets
Nickel coating and allergies
Medical facts indicate that the nickel plating (the usual finish) is a potent allergen. If you have an allergy, prevent direct skin contact or opt for coated magnets.
Medical interference
Medical warning: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have electronic implants.
Keep away from children
Product intended for adults. Small elements pose a choking risk, causing severe trauma. Keep out of reach of children and animals.
Operating temperature
Standard neodymium magnets (grade N) undergo demagnetization when the temperature exceeds 80°C. Damage is permanent.
Impact on smartphones
Remember: neodymium magnets generate a field that disrupts precision electronics. Keep a safe distance from your phone, tablet, and GPS.
Handling guide
Handle with care. Neodymium magnets act from a long distance and snap with massive power, often faster than you can react.
Do not drill into magnets
Machining of NdFeB material carries a risk of fire hazard. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Material brittleness
Despite the nickel coating, neodymium is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Magnetic media
Avoid bringing magnets near a purse, computer, or screen. The magnetism can destroy these devices and wipe information from cards.
Bodily injuries
Danger of trauma: The pulling power is so immense that it can result in blood blisters, crushing, and even bone fractures. Protective gloves are recommended.
