Advantages as well as disadvantages of Nd2Fe14B magnets.
Benefits
- They virtually do not lose strength, because even after ten years the decline in efficiency is only ~1% (based on calculations),
- They have excellent resistance to magnetism drop when exposed to opposing magnetic fields,
- Thanks to the elegant finish, the layer of Ni-Cu-Ni, gold-plated, or silver-plated gives an visually attractive appearance,
- They feature high magnetic induction at the operating surface, which improves attraction properties,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Considering the ability of flexible molding and customization to unique requirements, magnetic components can be manufactured in a wide range of shapes and sizes, which increases their versatility,
- Significant place in electronics industry – they are used in HDD drives, motor assemblies, advanced medical instruments, as well as industrial machines.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Disadvantages
- Brittleness is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a special holder, which not only secures them against impacts but also increases their durability
- When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their power 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
- They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited ability of creating nuts in the magnet and complicated shapes - preferred is cover - magnet mounting.
- Potential hazard related to microscopic parts of magnets pose a threat, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small elements of these devices are able to disrupt the diagnostic process medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Pull force analysis
Best holding force of the magnet in ideal parameters – what it depends on?
- on a base made of structural steel, perfectly concentrating the magnetic field
- with a cross-section of at least 10 mm
- with an ground contact surface
- without any insulating layer between the magnet and steel
- during detachment in a direction perpendicular to the mounting surface
- in neutral thermal conditions
Magnet lifting force in use – key factors
- Gap (betwixt the magnet and the metal), since even a microscopic distance (e.g. 0.5 mm) results in a reduction in force by up to 50% (this also applies to varnish, corrosion or debris).
- Load vector – highest force is obtained only during perpendicular pulling. The resistance to sliding of the magnet along the surface is usually several times lower (approx. 1/5 of the lifting capacity).
- Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Material composition – different alloys attracts identically. High carbon content weaken the attraction effect.
- Surface condition – ground elements ensure maximum contact, which improves field saturation. Uneven metal reduce efficiency.
- Temperature – heating the magnet causes a temporary drop of force. Check the thermal limit for a given model.
Lifting capacity was determined using a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under parallel forces the holding force is lower. Additionally, even a slight gap between the magnet’s surface and the plate reduces the load capacity.
H&S for magnets
Dust explosion hazard
Machining of NdFeB material carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Swallowing risk
Strictly keep magnets out of reach of children. Ingestion danger is high, and the consequences of magnets clamping inside the body are life-threatening.
Danger to pacemakers
Patients with a ICD should keep an safe separation from magnets. The magnetism can interfere with the operation of the implant.
Heat warning
Do not overheat. NdFeB magnets are sensitive to temperature. If you need operation above 80°C, look for HT versions (H, SH, UH).
Bodily injuries
Pinching hazard: The pulling power is so great that it can cause hematomas, pinching, and even bone fractures. Use thick gloves.
Magnet fragility
Despite the nickel coating, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.
Respect the power
Use magnets consciously. Their immense force can shock even professionals. Stay alert and respect their power.
Avoid contact if allergic
Studies show that nickel (the usual finish) is a potent allergen. If you have an allergy, avoid direct skin contact or opt for encased magnets.
Keep away from electronics
GPS units and smartphones are extremely sensitive to magnetism. Close proximity with a strong magnet can decalibrate the internal compass in your phone.
Electronic hazard
Device Safety: Neodymium magnets can ruin payment cards and sensitive devices (pacemakers, medical aids, timepieces).
