Advantages and disadvantages of Nd2Fe14B magnets.
Advantages
- They do not lose magnetism, even over approximately 10 years – the drop in lifting capacity is only ~1% (based on measurements),
- They have excellent resistance to magnetic field loss due to external fields,
- A magnet with a smooth nickel surface has an effective appearance,
- The surface of neodymium magnets generates a concentrated magnetic field – this is one of their assets,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
- In view of the possibility of precise forming and customization to specialized projects, magnetic components can be produced in a broad palette of geometric configurations, which expands the range of possible applications,
- Key role in innovative solutions – they are used in magnetic memories, brushless drives, medical equipment, as well as multitasking production systems.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Disadvantages
- At strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we recommend 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 prevent oxidation as well as corrosion.
- Due to limitations in creating threads and complex forms in magnets, we recommend using casing - magnetic mechanism.
- Health risk resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child safety. Additionally, small elements of these devices can 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
Highest magnetic holding force – what contributes to it?
- with the use of a yoke made of low-carbon steel, ensuring full magnetic saturation
- whose thickness equals approx. 10 mm
- with a surface perfectly flat
- without any air gap between the magnet and steel
- during pulling in a direction perpendicular to the mounting surface
- at ambient temperature room level
Lifting capacity in practice – influencing factors
- Distance (between the magnet and the plate), since even a microscopic distance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to paint, rust or dirt).
- Force direction – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
- Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet limits the attraction force (the magnet "punches through" it).
- Metal type – different alloys reacts the same. Alloy additives weaken the attraction effect.
- Surface quality – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
- Temperature – temperature increase results in weakening of induction. Check the maximum operating temperature for a given model.
Lifting capacity testing was carried out on a smooth plate of optimal thickness, under a perpendicular pulling force, whereas under parallel forces the load capacity is reduced by as much as 5 times. Moreover, even a minimal clearance between the magnet and the plate reduces the holding force.
Warnings
ICD Warning
For implant holders: Strong magnetic fields disrupt electronics. Keep minimum 30 cm distance or request help to handle the magnets.
Do not overheat magnets
Avoid heat. NdFeB magnets are susceptible to heat. If you require operation above 80°C, look for HT versions (H, SH, UH).
Crushing force
Mind your fingers. Two powerful magnets will join instantly with a force of massive weight, destroying anything in their path. Be careful!
Beware of splinters
Despite metallic appearance, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.
GPS and phone interference
An intense magnetic field interferes with the functioning of magnetometers in smartphones and navigation systems. Maintain magnets near a smartphone to prevent damaging the sensors.
Nickel coating and allergies
Certain individuals have a sensitization to nickel, which is the standard coating for NdFeB magnets. Extended handling may cause dermatitis. We recommend use safety gloves.
Powerful field
Handle with care. Neodymium magnets attract from a distance and snap with massive power, often quicker than you can move away.
Do not give to children
Adult use only. Small elements pose a choking risk, causing intestinal necrosis. Store away from children and animals.
Combustion hazard
Fire hazard: Neodymium dust is explosive. Do not process magnets without safety gear as this may cause fire.
Keep away from computers
Powerful magnetic fields can corrupt files on payment cards, HDDs, and storage devices. Maintain a gap of at least 10 cm.
