Strengths and weaknesses of rare earth magnets.
Strengths
- Their power is maintained, and after approximately 10 years it decreases only by ~1% (according to research),
- They show high resistance to demagnetization induced by external magnetic fields,
- By applying a reflective layer of silver, the element presents an nice look,
- Magnets have impressive magnetic induction on the outer side,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
- Thanks to the possibility of accurate forming and adaptation to custom requirements, magnetic components can be manufactured in a variety of geometric configurations, which expands the range of possible applications,
- Versatile presence in modern technologies – they are commonly used in computer drives, brushless drives, medical equipment, and modern systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which makes them useful in miniature devices
Disadvantages
- To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we suggest 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 those in rubber or plastics, which secure oxidation as well as corrosion.
- We suggest cover - magnetic mount, due to difficulties in realizing nuts inside the magnet and complex forms.
- Possible danger to health – tiny shards of magnets pose a threat, if swallowed, which gains importance in the context of child safety. Additionally, small components of these magnets are able to disrupt the diagnostic process medical when they are in the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Holding force characteristics
Best holding force of the magnet in ideal parameters – what it depends on?
- using a sheet made of high-permeability steel, acting as a circuit closing element
- whose transverse dimension reaches at least 10 mm
- with a plane cleaned and smooth
- without any clearance between the magnet and steel
- under vertical application of breakaway force (90-degree angle)
- in neutral thermal conditions
Impact of factors on magnetic holding capacity in practice
- Air gap (between the magnet and the metal), as even a very small clearance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
- Loading method – catalog parameter refers to pulling vertically. When attempting to slide, the magnet exhibits significantly lower power (typically approx. 20-30% of maximum force).
- Plate thickness – too thin steel does not close the flux, causing part of the flux to be escaped to the other side.
- Material type – ideal substrate is pure iron steel. Hardened steels may generate lower lifting capacity.
- Surface condition – ground elements ensure maximum contact, which improves force. Uneven metal reduce efficiency.
- Thermal conditions – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.
Warnings
Mechanical processing
Combustion risk: Rare earth powder is highly flammable. Do not process magnets in home conditions as this may cause fire.
Danger to pacemakers
Individuals with a ICD have to maintain an large gap from magnets. The magnetism can disrupt the functioning of the implant.
Maximum temperature
Keep cool. Neodymium magnets are sensitive to heat. If you require operation above 80°C, look for special high-temperature series (H, SH, UH).
Magnetic interference
Be aware: neodymium magnets produce a field that confuses precision electronics. Maintain a safe distance from your phone, tablet, and GPS.
Do not underestimate power
Handle with care. Rare earth magnets attract from a distance and snap with huge force, often faster than you can move away.
Electronic devices
Avoid bringing magnets close to a purse, laptop, or TV. The magnetic field can permanently damage these devices and wipe information from cards.
Serious injuries
Watch your fingers. Two large magnets will snap together immediately with a force of several hundred kilograms, destroying everything in their path. Be careful!
This is not a toy
These products are not toys. Swallowing multiple magnets can lead to them attracting across intestines, which constitutes a critical condition and necessitates urgent medical intervention.
Protective goggles
NdFeB magnets are sintered ceramics, which means they are prone to chipping. Clashing of two magnets leads to them cracking into shards.
Avoid contact if allergic
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If skin irritation occurs, immediately stop working with magnets and wear gloves.
