Advantages as well as disadvantages of neodymium magnets.
Benefits
- They do not lose power, even over around ten years – the reduction in lifting capacity is only ~1% (theoretically),
- Magnets perfectly resist against demagnetization caused by ambient magnetic noise,
- A magnet with a shiny gold surface has better aesthetics,
- Magnetic induction on the working layer of the magnet remains very high,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to the potential of free shaping and adaptation to unique needs, magnetic components can be created in a variety of geometric configurations, which amplifies use scope,
- Key role in innovative solutions – they are utilized in HDD drives, drive modules, advanced medical instruments, as well as other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which enables their usage in compact constructions
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a special holder, which not only protects them against impacts but also increases their durability
- Neodymium magnets lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Limited ability of producing threads in the magnet and complex shapes - preferred is a housing - magnet mounting.
- Possible danger to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child safety. It is also worth noting that tiny parts of these magnets can disrupt the diagnostic process medical in case of swallowing.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Best holding force of the magnet in ideal parameters – what it depends on?
- on a plate made of structural steel, perfectly concentrating the magnetic flux
- with a thickness no less than 10 mm
- with a surface perfectly flat
- with zero gap (without coatings)
- during detachment in a direction perpendicular to the mounting surface
- at room temperature
Key elements affecting lifting force
- Gap (betwixt the magnet and the metal), as even a very small clearance (e.g. 0.5 mm) results in a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or dirt).
- Loading method – catalog parameter refers to detachment vertically. When attempting to slide, the magnet exhibits significantly lower power (typically approx. 20-30% of maximum force).
- Plate thickness – too thin steel does not close the flux, causing part of the flux to be lost into the air.
- Metal type – different alloys reacts the same. High carbon content weaken the interaction with the magnet.
- Smoothness – full contact is obtained only on polished steel. Any scratches and bumps create air cushions, reducing force.
- Operating temperature – NdFeB sinters have a negative temperature coefficient. When it is hot they lose power, and at low temperatures gain strength (up to a certain limit).
Lifting capacity was assessed using a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular pulling force, however under parallel forces the lifting capacity is smaller. Moreover, even a small distance between the magnet’s surface and the plate lowers the lifting capacity.
Warnings
Dust is flammable
Drilling and cutting of neodymium magnets poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Conscious usage
Use magnets consciously. Their immense force can surprise even professionals. Plan your moves and do not underestimate their power.
This is not a toy
Strictly keep magnets away from children. Risk of swallowing is high, and the consequences of magnets clamping inside the body are very dangerous.
Serious injuries
Danger of trauma: The attraction force is so immense that it can result in hematomas, crushing, and broken bones. Protective gloves are recommended.
Nickel coating and allergies
Certain individuals have a contact allergy to Ni, which is the standard coating for neodymium magnets. Frequent touching may cause a rash. We suggest use safety gloves.
Protective goggles
Beware of splinters. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. Wear goggles.
Maximum temperature
Do not overheat. NdFeB magnets are susceptible to temperature. If you need resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Health Danger
For implant holders: Powerful magnets disrupt electronics. Maintain at least 30 cm distance or request help to handle the magnets.
Threat to navigation
An intense magnetic field interferes with the functioning of magnetometers in smartphones and navigation systems. Maintain magnets close to a device to prevent damaging the sensors.
Electronic hazard
Device Safety: Strong magnets can ruin data carriers and sensitive devices (pacemakers, medical aids, timepieces).
