Strengths and weaknesses of Nd2Fe14B magnets.
Benefits
- They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (based on calculations),
- They retain their magnetic properties even under strong external field,
- Thanks to the shimmering finish, the layer of Ni-Cu-Ni, gold, or silver gives an professional appearance,
- Neodymium magnets create maximum magnetic induction on a their surface, which ensures high operational effectiveness,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for operation at temperatures approaching 230°C and above...
- Thanks to the option of free molding and adaptation to custom requirements, magnetic components can be created in a wide range of shapes and sizes, which expands the range of possible applications,
- Versatile presence in modern technologies – they are utilized in mass storage devices, motor assemblies, advanced medical instruments, also technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which enables their usage in miniature devices
Disadvantages
- At strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- Neodymium magnets decrease 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 those in rubber or plastics, which prevent oxidation as well as corrosion.
- We suggest a housing - magnetic mechanism, due to difficulties in creating nuts inside the magnet and complicated shapes.
- Possible danger to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small components of these devices can be problematic in diagnostics medical in case of swallowing.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities
Lifting parameters
Maximum holding power of the magnet – what it depends on?
- on a block made of structural steel, effectively closing the magnetic flux
- possessing a thickness of minimum 10 mm to ensure full flux closure
- characterized by lack of roughness
- under conditions of gap-free contact (surface-to-surface)
- for force applied at a right angle (pull-off, not shear)
- in stable room temperature
Practical lifting capacity: influencing factors
- Gap (betwixt the magnet and the metal), since even a microscopic clearance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
- Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Material composition – not every steel reacts the same. Alloy additives worsen the interaction with the magnet.
- Plate texture – smooth surfaces ensure maximum contact, which increases force. Rough surfaces weaken the grip.
- Thermal conditions – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and in frost gain strength (up to a certain limit).
Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Moreover, even a small distance between the magnet and the plate lowers the load capacity.
Warnings
GPS and phone interference
An intense magnetic field disrupts the operation of compasses in phones and GPS navigation. Maintain magnets close to a device to avoid damaging the sensors.
Mechanical processing
Mechanical processing of NdFeB material carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Eye protection
Protect your eyes. Magnets can explode upon violent connection, ejecting sharp fragments into the air. Eye protection is mandatory.
Nickel coating and allergies
Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If redness occurs, immediately stop working with magnets and use protective gear.
Hand protection
Mind your fingers. Two large magnets will snap together instantly with a force of massive weight, destroying anything in their path. Be careful!
Thermal limits
Keep cool. Neodymium magnets are susceptible to temperature. If you need resistance above 80°C, ask us about HT versions (H, SH, UH).
Do not give to children
Only for adults. Tiny parts pose a choking risk, causing severe trauma. Store away from kids and pets.
Protect data
Data protection: Neodymium magnets can ruin payment cards and sensitive devices (heart implants, hearing aids, timepieces).
Respect the power
Use magnets consciously. Their huge power can shock even experienced users. Stay alert and respect their force.
Medical interference
Patients with a heart stimulator should keep an large gap from magnets. The magnetism can interfere with the functioning of the life-saving device.
