Advantages and disadvantages of Nd2Fe14B magnets.
Advantages
- They have unchanged lifting capacity, and over nearly ten years their attraction force decreases symbolically – ~1% (in testing),
- Magnets very well protect themselves against loss of magnetization caused by foreign field sources,
- In other words, due to the glossy layer of silver, the element gains a professional look,
- Neodymium magnets ensure maximum magnetic induction on a small surface, which allows for strong attraction,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Considering the option of flexible molding and adaptation to custom projects, NdFeB magnets can be manufactured in a variety of shapes and sizes, which increases their versatility,
- Versatile presence in advanced technology sectors – they serve a role in mass storage devices, drive modules, precision medical tools, and modern systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which enables their usage in small systems
Cons
- To avoid cracks under impact, we suggest using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited ability of creating threads in the magnet and complex shapes - recommended is a housing - magnet mounting.
- Health risk resulting from small fragments of magnets pose a threat, if swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, small elements of these magnets are able to disrupt the diagnostic process medical after entering the body.
- Due to neodymium price, their price is relatively high,
Lifting parameters
Maximum holding power of the magnet – what affects it?
- using a sheet made of high-permeability steel, acting as a circuit closing element
- with a cross-section minimum 10 mm
- with an polished touching surface
- without any clearance between the magnet and steel
- under axial application of breakaway force (90-degree angle)
- at room temperature
Magnet lifting force in use – key factors
- Gap (between the magnet and the plate), since even a microscopic distance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to paint, rust or debris).
- Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Plate thickness – too thin sheet does not accept the full field, causing part of the flux to be lost into the air.
- Material composition – different alloys reacts the same. Alloy additives worsen the interaction with the magnet.
- Surface structure – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Unevenness creates an air distance.
- Thermal factor – hot environment reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.
Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Moreover, even a small distance between the magnet and the plate lowers the lifting capacity.
H&S for magnets
Machining danger
Machining of NdFeB material poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Caution required
Handle magnets consciously. Their huge power can surprise even experienced users. Be vigilant and do not underestimate their force.
No play value
Adult use only. Small elements pose a choking risk, leading to severe trauma. Keep away from children and animals.
Medical implants
Patients with a ICD must keep an safe separation from magnets. The magnetism can disrupt the operation of the implant.
Threat to electronics
Avoid bringing magnets near a purse, laptop, or TV. The magnetism can destroy these devices and erase data from cards.
Permanent damage
Regular neodymium magnets (grade N) lose power when the temperature surpasses 80°C. This process is irreversible.
Sensitization to coating
Certain individuals suffer from a hypersensitivity to Ni, which is the typical protective layer for neodymium magnets. Prolonged contact can result in a rash. It is best to wear safety gloves.
Threat to navigation
Remember: neodymium magnets generate a field that disrupts sensitive sensors. Keep a separation from your mobile, tablet, and navigation systems.
Serious injuries
Danger of trauma: The attraction force is so immense that it can result in blood blisters, pinching, and broken bones. Use thick gloves.
Eye protection
NdFeB magnets are ceramic materials, meaning they are fragile like glass. Impact of two magnets leads to them shattering into small pieces.
