Advantages and disadvantages of Nd2Fe14B magnets.
Advantages
- Their strength is maintained, and after around 10 years it decreases only by ~1% (theoretically),
- They possess excellent resistance to magnetism drop due to external magnetic sources,
- In other words, due to the smooth surface of gold, the element gains visual value,
- The surface of neodymium magnets generates a strong magnetic field – this is a distinguishing feature,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
- Possibility of accurate machining as well as optimizing to complex needs,
- Huge importance in high-tech industry – they are utilized in hard drives, electric motors, medical equipment, and industrial machines.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Disadvantages
- At very strong impacts they can break, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- Neodymium magnets decrease their power 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
- They rust in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited possibility of producing nuts in the magnet and complex shapes - preferred is cover - mounting mechanism.
- Health risk related to microscopic parts of magnets are risky, in case of ingestion, which gains importance in the context of child health protection. Furthermore, small components of these products are able to complicate diagnosis medical when they are in the body.
- Due to expensive raw materials, their price is higher than average,
Holding force characteristics
Maximum lifting force for a neodymium magnet – what it depends on?
- with the application of a sheet made of special test steel, guaranteeing maximum field concentration
- possessing a massiveness of at least 10 mm to ensure full flux closure
- with a plane free of scratches
- with zero gap (without impurities)
- for force applied at a right angle (pull-off, not shear)
- at temperature approx. 20 degrees Celsius
Practical aspects of lifting capacity – factors
- Air gap (between the magnet and the plate), since even a very small distance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to varnish, rust or dirt).
- Angle of force application – maximum parameter is obtained only during pulling at a 90° angle. The shear force of the magnet along the surface is usually several times lower (approx. 1/5 of the lifting capacity).
- Base massiveness – too thin sheet does not close the flux, causing part of the power to be lost into the air.
- Plate material – low-carbon steel attracts best. Alloy admixtures lower magnetic permeability and holding force.
- Surface finish – full contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
- Thermal factor – high temperature weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was measured using a smooth steel plate of optimal thickness (min. 20 mm), under vertically applied force, in contrast under parallel forces the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.
Safety rules for work with NdFeB magnets
Combustion hazard
Combustion risk: Rare earth powder is explosive. Avoid machining magnets without safety gear as this may cause fire.
Allergy Warning
It is widely known that nickel (the usual finish) is a common allergen. If you have an allergy, avoid direct skin contact or choose encased magnets.
Bone fractures
Large magnets can crush fingers in a fraction of a second. Under no circumstances place your hand between two strong magnets.
Swallowing risk
These products are not toys. Accidental ingestion of a few magnets may result in them pinching intestinal walls, which poses a severe health hazard and requires immediate surgery.
Life threat
Patients with a heart stimulator must keep an large gap from magnets. The magnetism can interfere with the functioning of the implant.
Magnets are brittle
Protect your eyes. Magnets can explode upon violent connection, launching shards into the air. Eye protection is mandatory.
Threat to electronics
Device Safety: Neodymium magnets can ruin data carriers and delicate electronics (heart implants, hearing aids, mechanical watches).
Phone sensors
Be aware: rare earth magnets generate a field that disrupts sensitive sensors. Keep a safe distance from your mobile, device, and GPS.
Demagnetization risk
Do not overheat. NdFeB magnets are sensitive to temperature. If you require operation above 80°C, look for special high-temperature series (H, SH, UH).
Immense force
Handle magnets consciously. Their powerful strength can surprise even professionals. Stay alert and do not underestimate their force.
