Advantages as well as disadvantages of neodymium magnets.
Pros
- They do not lose power, even during approximately 10 years – the drop in strength is only ~1% (according to tests),
- They have excellent resistance to magnetic field loss due to external magnetic sources,
- By using a lustrous layer of silver, the element has an elegant look,
- They are known for high magnetic induction at the operating surface, making them more effective,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
- In view of the potential of free forming and customization to unique requirements, NdFeB magnets can be modeled in a wide range of geometric configurations, which makes them more universal,
- Wide application in electronics industry – they serve a role in hard drives, drive modules, medical devices, as well as other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which makes them useful in small systems
Weaknesses
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also improves its resistance to damage
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
- We suggest a housing - magnetic holder, due to difficulties in producing threads inside the magnet and complicated shapes.
- Potential hazard related to microscopic parts of magnets are risky, in case of ingestion, which gains importance in the aspect of protecting the youngest. It is also worth noting that small elements of these devices can disrupt the diagnostic process medical in case of swallowing.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Detachment force of the magnet in optimal conditions – what contributes to it?
- with the application of a yoke made of low-carbon steel, guaranteeing maximum field concentration
- whose thickness is min. 10 mm
- characterized by lack of roughness
- with total lack of distance (no coatings)
- under perpendicular application of breakaway force (90-degree angle)
- at standard ambient temperature
What influences lifting capacity in practice
- Clearance – existence of any layer (paint, dirt, air) acts as an insulator, which lowers capacity steeply (even by 50% at 0.5 mm).
- Force direction – catalog parameter refers to detachment vertically. When attempting to slide, the magnet holds significantly lower power (often approx. 20-30% of maximum force).
- Substrate thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Steel grade – the best choice is pure iron steel. Hardened steels may generate lower lifting capacity.
- Plate texture – ground elements guarantee perfect abutment, which improves field saturation. Rough surfaces weaken the grip.
- Thermal conditions – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).
Lifting capacity was assessed with the use of a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, however under parallel forces the holding force is lower. Moreover, even a small distance between the magnet and the plate reduces the load capacity.
Warnings
Do not give to children
NdFeB magnets are not toys. Swallowing several magnets may result in them attracting across intestines, which constitutes a critical condition and necessitates urgent medical intervention.
Physical harm
Pinching hazard: The pulling power is so immense that it can cause blood blisters, crushing, and broken bones. Use thick gloves.
Allergic reactions
Nickel alert: The nickel-copper-nickel coating contains nickel. If an allergic reaction happens, immediately stop handling magnets and wear gloves.
Heat warning
Watch the temperature. Exposing the magnet above 80 degrees Celsius will ruin its properties and pulling force.
GPS and phone interference
A strong magnetic field interferes with the operation of magnetometers in phones and navigation systems. Maintain magnets close to a smartphone to avoid damaging the sensors.
Caution required
Before starting, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Be predictive.
Material brittleness
Protect your eyes. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. Wear goggles.
Threat to electronics
Equipment safety: Strong magnets can ruin data carriers and sensitive devices (heart implants, hearing aids, timepieces).
Combustion hazard
Powder generated during grinding of magnets is combustible. Avoid drilling into magnets unless you are an expert.
Pacemakers
Individuals with a pacemaker have to maintain an safe separation from magnets. The magnetism can interfere with the functioning of the implant.
