Advantages as well as disadvantages of Nd2Fe14B magnets.
Advantages
- They retain attractive force for almost ten years – the drop is just ~1% (according to analyses),
- Neodymium magnets are exceptionally resistant to magnetic field loss caused by magnetic disturbances,
- The use of an metallic layer of noble metals (nickel, gold, silver) causes the element to look better,
- The surface of neodymium magnets generates a maximum magnetic field – this is one of their assets,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Possibility of accurate forming as well as adjusting to concrete requirements,
- Fundamental importance in future technologies – they serve a role in computer drives, drive modules, diagnostic systems, and complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which makes them useful in small systems
Weaknesses
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also improves its resistance to damage
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 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 and corrosion.
- We recommend casing - magnetic mount, due to difficulties in realizing threads inside the magnet and complicated forms.
- Potential hazard to health – tiny shards of magnets can be dangerous, in case of ingestion, which becomes key in the context of child health protection. Furthermore, small components of these products can complicate diagnosis medical in case of swallowing.
- With budget limitations the cost of neodymium magnets is economically unviable,
Holding force characteristics
Maximum holding power of the magnet – what contributes to it?
- on a plate made of structural steel, perfectly concentrating the magnetic flux
- whose thickness is min. 10 mm
- with a plane cleaned and smooth
- without any insulating layer between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- at standard ambient temperature
What influences lifting capacity in practice
- Clearance – existence of any layer (rust, dirt, gap) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
- Force direction – catalog parameter refers to pulling vertically. When applying parallel force, the magnet exhibits significantly lower power (often approx. 20-30% of maximum force).
- Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
- Material composition – not every steel reacts the same. High carbon content worsen the attraction effect.
- Surface quality – the more even the plate, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
- Temperature influence – high temperature reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity was determined by applying a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular pulling force, however under parallel forces the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet and the plate reduces the load capacity.
Warnings
Product not for children
Always store magnets out of reach of children. Choking hazard is significant, and the effects of magnets connecting inside the body are tragic.
Crushing risk
Watch your fingers. Two powerful magnets will snap together instantly with a force of several hundred kilograms, destroying everything in their path. Be careful!
Maximum temperature
Regular neodymium magnets (grade N) lose power when the temperature exceeds 80°C. The loss of strength is permanent.
Avoid contact if allergic
Studies show that the nickel plating (standard magnet coating) is a common allergen. For allergy sufferers, prevent touching magnets with bare hands or choose encased magnets.
Precision electronics
Navigation devices and mobile phones are highly susceptible to magnetism. Direct contact with a strong magnet can decalibrate the internal compass in your phone.
Handling guide
Before use, check safety instructions. Uncontrolled attraction can break the magnet or hurt your hand. Be predictive.
Life threat
Medical warning: Neodymium magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.
Cards and drives
Avoid bringing magnets near a purse, laptop, or TV. The magnetism can destroy these devices and wipe information from cards.
Dust explosion hazard
Drilling and cutting of neodymium magnets carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Shattering risk
NdFeB magnets are sintered ceramics, meaning they are fragile like glass. Impact of two magnets will cause them shattering into shards.
