Advantages and disadvantages of rare earth magnets.
Benefits
- They do not lose magnetism, even during around 10 years – the reduction in power is only ~1% (based on measurements),
- They retain their magnetic properties even under strong external field,
- A magnet with a shiny nickel surface is more attractive,
- Magnetic induction on the working part of the magnet remains impressive,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Possibility of precise creating as well as adapting to defined conditions,
- Wide application in advanced technology sectors – they are utilized in data components, motor assemblies, precision medical tools, as well as industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which makes them useful in small systems
Weaknesses
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
- NdFeB magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Limited ability of making nuts in the magnet and complex forms - recommended is a housing - magnetic holder.
- Potential hazard related to microscopic parts of magnets are risky, if swallowed, which gains importance in the context of child health protection. Furthermore, small components of these magnets can be problematic in diagnostics medical after entering the body.
- With large orders the cost of neodymium magnets is economically unviable,
Lifting parameters
Maximum holding power of the magnet – what affects it?
- on a base made of mild steel, effectively closing the magnetic flux
- with a thickness minimum 10 mm
- with an polished touching surface
- without the slightest air gap between the magnet and steel
- for force acting at a right angle (pull-off, not shear)
- at conditions approx. 20°C
What influences lifting capacity in practice
- Distance – existence of any layer (paint, tape, air) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Angle of force application – maximum parameter is obtained only during pulling at a 90° angle. The force required to slide of the magnet along the surface is typically many times smaller (approx. 1/5 of the lifting capacity).
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
- Metal type – not every steel reacts the same. Alloy additives worsen the attraction effect.
- Plate texture – ground elements ensure maximum contact, which increases field saturation. Rough surfaces reduce efficiency.
- Temperature influence – hot environment weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.
Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Moreover, even a small distance between the magnet’s surface and the plate decreases the load capacity.
Safety rules for work with NdFeB magnets
Caution required
Exercise caution. Neodymium magnets attract from a distance and connect with massive power, often faster than you can move away.
Finger safety
Big blocks can crush fingers instantly. Do not put your hand between two strong magnets.
Phone sensors
Be aware: rare earth magnets produce a field that disrupts sensitive sensors. Keep a separation from your phone, device, and GPS.
Magnet fragility
Watch out for shards. Magnets can explode upon violent connection, launching shards into the air. Eye protection is mandatory.
Nickel allergy
Some people have a sensitization to nickel, which is the standard coating for neodymium magnets. Frequent touching may cause a rash. We suggest use protective gloves.
Do not give to children
Only for adults. Small elements can be swallowed, causing severe trauma. Keep out of reach of children and animals.
Pacemakers
Individuals with a ICD should maintain an absolute distance from magnets. The magnetism can stop the operation of the implant.
Do not overheat magnets
Avoid heat. Neodymium magnets are sensitive to heat. If you require resistance above 80°C, inquire about special high-temperature series (H, SH, UH).
Keep away from computers
Avoid bringing magnets near a wallet, laptop, or TV. The magnetic field can irreversibly ruin these devices and erase data from cards.
Combustion hazard
Mechanical processing of neodymium magnets poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
