Strengths and weaknesses of Nd2Fe14B magnets.
Benefits
- They virtually do not lose strength, because even after ten years the performance loss is only ~1% (in laboratory conditions),
- Magnets very well defend themselves against demagnetization caused by external fields,
- Thanks to the elegant finish, the surface of nickel, gold, or silver gives an clean appearance,
- Magnets are characterized by impressive magnetic induction on the active area,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling operation at temperatures reaching 230°C and above...
- Possibility of precise modeling and optimizing to complex needs,
- Universal use in innovative solutions – they are commonly used in data components, electromotive mechanisms, advanced medical instruments, as well as industrial machines.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Disadvantages
- To avoid cracks under impact, we recommend using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
- When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and 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 when using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Limited possibility of creating nuts in the magnet and complicated shapes - preferred is a housing - magnetic holder.
- Possible danger resulting from small fragments of magnets pose a threat, if swallowed, which is particularly important in the context of child health protection. Furthermore, small elements of these products are able to complicate diagnosis medical in case of swallowing.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Pull force analysis
Optimal lifting capacity of a neodymium magnet – what it depends on?
- with the use of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
- with a cross-section no less than 10 mm
- with a surface free of scratches
- without the slightest air gap between the magnet and steel
- under axial application of breakaway force (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Impact of factors on magnetic holding capacity in practice
- Distance (between the magnet and the metal), because even a microscopic distance (e.g. 0.5 mm) leads to a drastic drop in force by up to 50% (this also applies to varnish, rust or debris).
- Loading method – catalog parameter refers to pulling vertically. When attempting to slide, the magnet exhibits much less (often approx. 20-30% of maximum force).
- Base massiveness – insufficiently thick sheet does not close the flux, causing part of the power to be escaped into the air.
- Metal type – not every steel reacts the same. Alloy additives worsen the interaction with the magnet.
- Smoothness – full contact is possible only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
- Thermal environment – heating the magnet causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.
Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the load capacity is reduced by as much as fivefold. Additionally, even a minimal clearance between the magnet’s surface and the plate lowers the load capacity.
Safety rules for work with neodymium magnets
ICD Warning
For implant holders: Powerful magnets disrupt electronics. Keep minimum 30 cm distance or request help to handle the magnets.
Power loss in heat
Watch the temperature. Heating the magnet to high heat will ruin its properties and strength.
Magnetic media
Avoid bringing magnets close to a purse, laptop, or screen. The magnetic field can permanently damage these devices and erase data from cards.
Protective goggles
Beware of splinters. Magnets can explode upon uncontrolled impact, launching shards into the air. We recommend safety glasses.
Pinching danger
Watch your fingers. Two large magnets will join immediately with a force of several hundred kilograms, crushing anything in their path. Be careful!
Do not underestimate power
Handle magnets consciously. Their powerful strength can shock even professionals. Plan your moves and do not underestimate their power.
No play value
Neodymium magnets are not toys. Accidental ingestion of several magnets may result in them connecting inside the digestive tract, which constitutes a severe health hazard and requires urgent medical intervention.
Threat to navigation
Note: rare earth magnets produce a field that interferes with precision electronics. Maintain a separation from your phone, tablet, and GPS.
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.
Skin irritation risks
Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If skin irritation appears, cease working with magnets and use protective gear.
