Other offers
Advantages as well as disadvantages of neodymium magnets.
Advantages
- They retain magnetic properties for around 10 years – the drop is just ~1% (based on simulations),
- They possess excellent resistance to weakening of magnetic properties as a result of external magnetic sources,
- The use of an metallic coating of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- They are known for high magnetic induction at the operating surface, making them more effective,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling functioning at temperatures reaching 230°C and above...
- Possibility of exact shaping and modifying to atypical applications,
- Fundamental importance in modern industrial fields – they are utilized in HDD drives, drive modules, advanced medical instruments, as well as industrial machines.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Cons
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a steel housing, which not only protects them against impacts but also increases their durability
- Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
- Limited possibility of making threads in the magnet and complicated forms - preferred is casing - magnet mounting.
- Possible danger resulting from small fragments of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child safety. It is also worth noting that tiny parts of these magnets can disrupt the diagnostic process medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Best holding force of the magnet in ideal parameters – what it depends on?
- using a base made of high-permeability steel, functioning as a magnetic yoke
- with a cross-section no less than 10 mm
- characterized by lack of roughness
- with direct contact (without coatings)
- during pulling in a direction vertical to the plane
- in neutral thermal conditions
Magnet lifting force in use – key factors
- Gap (betwixt the magnet and the plate), because even a tiny clearance (e.g. 0.5 mm) can cause a reduction in force by up to 50% (this also applies to paint, corrosion or debris).
- Loading method – catalog parameter refers to detachment vertically. When applying parallel force, the magnet exhibits much less (typically approx. 20-30% of nominal force).
- Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Material composition – different alloys attracts identically. Alloy additives worsen the interaction with the magnet.
- Surface quality – the more even the plate, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
- Thermal conditions – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and at low temperatures they can be stronger (up to a certain limit).
Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under shearing force the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate reduces the holding force.
Precautions when working with neodymium magnets
Implant safety
People with a ICD must keep an safe separation from magnets. The magnetism can disrupt the operation of the life-saving device.
Thermal limits
Avoid heat. Neodymium magnets are susceptible to heat. If you need resistance above 80°C, ask us about HT versions (H, SH, UH).
Swallowing risk
Always keep magnets away from children. Ingestion danger is high, and the consequences of magnets clamping inside the body are life-threatening.
Handling guide
Exercise caution. Neodymium magnets act from a long distance and snap with massive power, often quicker than you can react.
Skin irritation risks
A percentage of the population experience a sensitization to Ni, which is the standard coating for NdFeB magnets. Frequent touching may cause skin redness. We strongly advise wear safety gloves.
Impact on smartphones
Be aware: rare earth magnets produce a field that confuses sensitive sensors. Keep a separation from your mobile, device, and navigation systems.
Do not drill into magnets
Drilling and cutting of NdFeB material poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Bodily injuries
Large magnets can break fingers instantly. Never place your hand betwixt two strong magnets.
Eye protection
Protect your eyes. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. Eye protection is mandatory.
Data carriers
Powerful magnetic fields can corrupt files on credit cards, hard drives, and other magnetic media. Keep a distance of at least 10 cm.
