Pros as well as cons of neodymium magnets.
Benefits
- They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (according to literature),
- They are resistant to demagnetization induced by external disturbances,
- The use of an refined layer of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- The surface of neodymium magnets generates a unique magnetic field – this is a key feature,
- 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...
- Thanks to freedom in shaping and the capacity to adapt to complex applications,
- Wide application in future technologies – they serve a role in data components, drive modules, advanced medical instruments, as well as industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which allows their use in small systems
Cons
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a strong case, which not only secures them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
- We suggest cover - magnetic mount, due to difficulties in creating threads inside the magnet and complicated forms.
- Possible danger to health – tiny shards of magnets pose a threat, in case of ingestion, which gains importance in the context of child health protection. It is also worth noting that small components of these products can complicate diagnosis 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
Maximum lifting force for a neodymium magnet – what contributes to it?
- on a block made of structural steel, perfectly concentrating the magnetic flux
- whose transverse dimension equals approx. 10 mm
- with an ground touching surface
- with direct contact (no paint)
- during detachment in a direction vertical to the plane
- at room temperature
Lifting capacity in practice – influencing factors
- Distance – existence of foreign body (rust, dirt, air) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Direction of force – maximum parameter is reached only during pulling at a 90° angle. The shear force of the magnet along the plate is usually several times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
- Material type – the best choice is high-permeability steel. Hardened steels may attract less.
- Plate texture – ground elements ensure maximum contact, which improves field saturation. Uneven metal reduce efficiency.
- Thermal environment – heating the magnet causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.
Lifting capacity was determined with the use of a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, however under shearing force the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate lowers the load capacity.
Warnings
Mechanical processing
Fire hazard: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this risks ignition.
Skin irritation risks
Allergy Notice: The nickel-copper-nickel coating contains nickel. If redness happens, cease handling magnets and use protective gear.
Eye protection
Watch out for shards. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. We recommend safety glasses.
Finger safety
Large magnets can smash fingers in a fraction of a second. Do not place your hand betwixt two attracting surfaces.
Immense force
Handle magnets consciously. Their powerful strength can surprise even professionals. Be vigilant and respect their power.
Adults only
Product intended for adults. Tiny parts pose a choking risk, causing serious injuries. Keep out of reach of children and animals.
Precision electronics
A strong magnetic field negatively affects the operation of compasses in phones and navigation systems. Keep magnets close to a device to prevent breaking the sensors.
Medical interference
Life threat: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have medical devices.
Demagnetization risk
Regular neodymium magnets (N-type) lose power when the temperature surpasses 80°C. The loss of strength is permanent.
Keep away from computers
Avoid bringing magnets close to a wallet, computer, or TV. The magnetic field can permanently damage these devices and erase data from cards.
