Advantages and disadvantages of rare earth magnets.
Benefits
- They retain full power for nearly 10 years – the drop is just ~1% (in theory),
- They have excellent resistance to magnetic field loss as a result of opposing magnetic fields,
- In other words, due to the reflective surface of silver, the element gains visual value,
- The surface of neodymium magnets generates a powerful magnetic field – this is one of their assets,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Due to the potential of free forming and adaptation to specialized projects, neodymium magnets can be created in a variety of forms and dimensions, which increases their versatility,
- Significant place in advanced technology sectors – they find application in computer drives, brushless drives, medical equipment, also other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which allows their use in miniature devices
Cons
- To avoid cracks under impact, we recommend using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
- We recommend casing - magnetic mount, due to difficulties in realizing nuts inside the magnet and complex shapes.
- Possible danger related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child safety. It is also worth noting that small elements of these products can be problematic in diagnostics medical when they are in the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Detachment force of the magnet in optimal conditions – what it depends on?
- on a block made of structural steel, optimally conducting the magnetic field
- possessing a thickness of at least 10 mm to ensure full flux closure
- with a surface cleaned and smooth
- without any air gap between the magnet and steel
- under axial force direction (90-degree angle)
- at room temperature
Lifting capacity in practice – influencing factors
- Gap (betwixt the magnet and the metal), because even a very small distance (e.g. 0.5 mm) leads to a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
- Loading method – declared lifting capacity refers to pulling vertically. When slipping, the magnet exhibits much less (typically approx. 20-30% of nominal force).
- Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Metal type – not every steel reacts the same. High carbon content weaken the interaction with the magnet.
- Plate texture – smooth surfaces guarantee perfect abutment, which improves field saturation. Uneven metal weaken the grip.
- Thermal environment – heating the magnet causes a temporary drop of induction. Check the thermal limit for a given model.
Lifting capacity testing was carried out on a smooth plate of optimal thickness, under perpendicular forces, however under parallel forces the load capacity is reduced by as much as 5 times. In addition, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.
H&S for magnets
GPS and phone interference
A strong magnetic field interferes with the operation of compasses in phones and navigation systems. Do not bring magnets close to a smartphone to avoid damaging the sensors.
Adults only
NdFeB magnets are not suitable for play. Swallowing multiple magnets may result in them attracting across intestines, which poses a severe health hazard and requires immediate surgery.
Respect the power
Handle magnets consciously. Their huge power can shock even professionals. Stay alert and do not underestimate their power.
Skin irritation risks
Some people experience a sensitization to Ni, which is the common plating for NdFeB magnets. Frequent touching can result in a rash. We suggest wear safety gloves.
Demagnetization risk
Keep cool. NdFeB magnets are susceptible to temperature. If you require resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Fragile material
Neodymium magnets are ceramic materials, meaning they are fragile like glass. Impact of two magnets will cause them shattering into small pieces.
Life threat
Life threat: Neodymium magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.
Data carriers
Intense magnetic fields can corrupt files on payment cards, hard drives, and storage devices. Stay away of at least 10 cm.
Machining danger
Dust created during cutting of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
Crushing risk
Mind your fingers. Two powerful magnets will join immediately with a force of massive weight, destroying anything in their path. Be careful!
