Advantages and disadvantages of Nd2Fe14B magnets.
Advantages
- Their power is maintained, and after around ten years it drops only by ~1% (theoretically),
- They do not lose their magnetic properties even under strong external field,
- By applying a shiny layer of gold, the element has an modern look,
- The surface of neodymium magnets generates a maximum magnetic field – this is a key feature,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Possibility of individual forming and adjusting to concrete conditions,
- Wide application in advanced technology sectors – they are commonly used in mass storage devices, electromotive mechanisms, medical equipment, and complex engineering applications.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Disadvantages
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only protects the magnet but also increases its resistance to damage
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (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 extremely resistant to heat
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Limited ability of creating threads in the magnet and complicated shapes - recommended is cover - mounting mechanism.
- Potential hazard resulting from small fragments of magnets pose a threat, in case of ingestion, which is particularly important in the context of child safety. It is also worth noting that tiny parts of these magnets are able to complicate diagnosis medical after entering the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Pull force analysis
Maximum holding power of the magnet – what contributes to it?
- with the application of a yoke made of low-carbon steel, ensuring full magnetic saturation
- whose transverse dimension reaches at least 10 mm
- with a plane cleaned and smooth
- with zero gap (no coatings)
- for force applied at a right angle (pull-off, not shear)
- at standard ambient temperature
Lifting capacity in practice – influencing factors
- Clearance – existence of foreign body (paint, dirt, air) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Force direction – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet exhibits much less (often approx. 20-30% of maximum force).
- Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Material composition – not every steel attracts identically. Alloy additives weaken the interaction with the magnet.
- Base smoothness – the more even the plate, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
- Thermal environment – heating the magnet results in weakening of induction. Check the thermal limit for a given model.
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under perpendicular forces, however under parallel forces the load capacity is reduced by as much as fivefold. Additionally, even a slight gap between the magnet’s surface and the plate lowers the load capacity.
H&S for magnets
Precision electronics
A powerful magnetic field negatively affects the operation of compasses in phones and GPS navigation. Do not bring magnets near a device to prevent damaging the sensors.
Protective goggles
Despite the nickel coating, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Power loss in heat
Keep cool. Neodymium magnets are susceptible to heat. If you require resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Dust explosion hazard
Mechanical processing of NdFeB material carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Medical implants
Medical warning: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have electronic implants.
Bone fractures
Watch your fingers. Two large magnets will snap together immediately with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!
Allergy Warning
It is widely known that nickel (the usual finish) is a common allergen. For allergy sufferers, refrain from direct skin contact or choose versions in plastic housing.
Immense force
Before use, read the rules. Sudden snapping can destroy the magnet or injure your hand. Be predictive.
Threat to electronics
Avoid bringing magnets close to a purse, computer, or screen. The magnetism can permanently damage these devices and erase data from cards.
Adults only
Strictly keep magnets out of reach of children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are fatal.
