Strengths as well as weaknesses of Nd2Fe14B magnets.
Strengths
- They retain magnetic properties for nearly 10 years – the drop is just ~1% (based on simulations),
- They show high resistance to demagnetization induced by external field influence,
- The use of an aesthetic layer of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- The surface of neodymium magnets generates a intense magnetic field – this is a key feature,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- Thanks to freedom in shaping and the capacity to adapt to client solutions,
- Versatile presence in innovative solutions – they find application in hard drives, electric drive systems, medical equipment, as well as other advanced devices.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Limitations
- At strong impacts they can break, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- We warn that neodymium magnets can reduce their power 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 corrode. Therefore when using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in realizing nuts and complicated forms in magnets, we recommend using a housing - magnetic mechanism.
- Health risk related to microscopic parts of magnets can be dangerous, in case of ingestion, which gains importance in the context of child safety. Furthermore, small elements of these products are able to complicate diagnosis medical when they are in the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Maximum holding power of the magnet – what contributes to it?
- with the use of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
- whose transverse dimension is min. 10 mm
- with a surface perfectly flat
- under conditions of gap-free contact (metal-to-metal)
- for force applied at a right angle (in the magnet axis)
- at room temperature
Practical lifting capacity: influencing factors
- Air gap (between the magnet and the metal), because 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, corrosion or dirt).
- Angle of force application – maximum parameter is available only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is standardly several times lower (approx. 1/5 of the lifting capacity).
- Steel thickness – insufficiently thick steel causes magnetic saturation, causing part of the power to be escaped to the other side.
- Material type – ideal substrate is high-permeability steel. Stainless steels may have worse magnetic properties.
- Smoothness – ideal contact is obtained only on polished steel. Any scratches and bumps create air cushions, reducing force.
- Temperature influence – hot environment weakens magnetic field. Too high temperature can permanently demagnetize the magnet.
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under perpendicular forces, whereas under parallel forces the holding force is lower. In addition, even a minimal clearance between the magnet and the plate lowers the lifting capacity.
Safety rules for work with neodymium magnets
Bone fractures
Risk of injury: The pulling power is so immense that it can result in blood blisters, crushing, and even bone fractures. Protective gloves are recommended.
Do not underestimate power
Be careful. Rare earth magnets attract from a long distance and snap with massive power, often quicker than you can react.
GPS Danger
Remember: rare earth magnets produce a field that interferes with sensitive sensors. Maintain a safe distance from your mobile, device, and GPS.
This is not a toy
Only for adults. Small elements pose a choking risk, causing intestinal necrosis. Keep out of reach of children and animals.
Do not drill into magnets
Powder generated during cutting of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.
Nickel allergy
It is widely known that nickel (the usual finish) is a potent allergen. For allergy sufferers, avoid direct skin contact or select coated magnets.
Pacemakers
For implant holders: Powerful magnets disrupt electronics. Keep at least 30 cm distance or ask another person to work with the magnets.
Risk of cracking
Despite metallic appearance, neodymium is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Power loss in heat
Watch the temperature. Heating the magnet above 80 degrees Celsius will destroy its magnetic structure and pulling force.
Magnetic media
Data protection: Strong magnets can damage payment cards and sensitive devices (heart implants, medical aids, mechanical watches).
