Advantages as well as disadvantages of Nd2Fe14B magnets.
Benefits
- They virtually do not lose strength, because even after ten years the performance loss is only ~1% (in laboratory conditions),
- They do not lose their magnetic properties even under external field action,
- The use of an metallic coating of noble metals (nickel, gold, silver) causes the element to present itself better,
- Neodymium magnets ensure maximum magnetic induction on a their surface, which increases force concentration,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- Possibility of custom forming and modifying to concrete needs,
- Universal use in modern industrial fields – they serve a role in data components, electric drive systems, medical equipment, and technologically advanced constructions.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Limitations
- To avoid cracks under impact, we recommend using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
- NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
- We recommend a housing - magnetic mechanism, due to difficulties in realizing threads inside the magnet and complicated forms.
- Health risk related to microscopic parts of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child safety. Additionally, small components of these devices are able to disrupt the diagnostic process 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 contributes to it?
- on a base made of structural steel, optimally conducting the magnetic flux
- possessing a massiveness of min. 10 mm to avoid saturation
- with an polished contact surface
- with direct contact (no paint)
- during pulling in a direction perpendicular to the mounting surface
- at conditions approx. 20°C
Practical aspects of lifting capacity – factors
- Gap (between the magnet and the plate), since even a very small distance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
- Loading method – catalog parameter refers to detachment vertically. When slipping, the magnet holds much less (typically approx. 20-30% of maximum force).
- Substrate thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Steel grade – the best choice is high-permeability steel. Cast iron may attract less.
- Surface condition – ground elements ensure maximum contact, which improves force. Uneven metal weaken the grip.
- Thermal factor – high temperature weakens pulling force. Too high temperature can permanently damage the magnet.
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under a perpendicular pulling force, however under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a small distance between the magnet’s surface and the plate reduces the lifting capacity.
Precautions when working with NdFeB magnets
Mechanical processing
Drilling and cutting of NdFeB material carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Handling guide
Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Be predictive.
Bodily injuries
Protect your hands. Two large magnets will join immediately with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!
Magnetic interference
Navigation devices and mobile phones are extremely sensitive to magnetic fields. Close proximity with a strong magnet can decalibrate the sensors in your phone.
Eye protection
Beware of splinters. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. Eye protection is mandatory.
Demagnetization risk
Avoid heat. NdFeB magnets are sensitive to heat. If you require resistance above 80°C, ask us about HT versions (H, SH, UH).
Warning for heart patients
Warning for patients: Strong magnetic fields affect electronics. Keep minimum 30 cm distance or ask another person to handle the magnets.
Threat to electronics
Intense magnetic fields can destroy records on payment cards, hard drives, and other magnetic media. Stay away of at least 10 cm.
Danger to the youngest
Absolutely keep magnets away from children. Ingestion danger is significant, and the consequences of magnets clamping inside the body are fatal.
Allergy Warning
Medical facts indicate that nickel (the usual finish) is a strong allergen. For allergy sufferers, prevent direct skin contact or select versions in plastic housing.
