Advantages and disadvantages of Nd2Fe14B magnets.
Strengths
- They retain attractive force for nearly 10 years – the drop is just ~1% (in theory),
- They are extremely resistant to demagnetization induced by external disturbances,
- In other words, due to the smooth layer of gold, the element looks attractive,
- Magnetic induction on the top side of the magnet is impressive,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling functioning at temperatures approaching 230°C and above...
- Possibility of exact creating and adapting to defined conditions,
- Fundamental importance in high-tech industry – they are utilized in computer drives, drive modules, medical equipment, and modern systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a special holder, which not only protects them against impacts but also increases their durability
- Neodymium magnets lose their strength 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 durability even at temperatures up to 230°C
- They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Due to limitations in realizing nuts and complex shapes in magnets, we propose using cover - magnetic holder.
- Possible danger to health – tiny shards of magnets are risky, in case of ingestion, which becomes key in the aspect of protecting the youngest. Furthermore, small components of these products can complicate diagnosis medical after entering the body.
- Due to complex production process, their price is higher than average,
Lifting parameters
Highest magnetic holding force – what it depends on?
- with the use of a yoke made of special test steel, ensuring full magnetic saturation
- with a cross-section of at least 10 mm
- characterized by smoothness
- with total lack of distance (no coatings)
- during pulling in a direction vertical to the mounting surface
- at room temperature
Determinants of lifting force in real conditions
- Distance – the presence of any layer (paint, dirt, gap) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
- Direction of force – highest force is available only during perpendicular pulling. 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 sheet does not close the flux, causing part of the power to be lost to the other side.
- Steel grade – the best choice is high-permeability steel. Hardened steels may attract less.
- Surface quality – the more even the surface, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
- Thermal factor – hot environment reduces magnetic field. Too high temperature can permanently demagnetize the magnet.
Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under parallel forces the load capacity is reduced by as much as 75%. Moreover, even a minimal clearance between the magnet and the plate reduces the load capacity.
H&S for magnets
Safe distance
Do not bring magnets near a purse, computer, or TV. The magnetism can permanently damage these devices and erase data from cards.
Life threat
For implant holders: Strong magnetic fields disrupt electronics. Maintain minimum 30 cm distance or ask another person to work with the magnets.
Demagnetization risk
Keep cool. NdFeB magnets are sensitive to heat. If you require operation above 80°C, look for special high-temperature series (H, SH, UH).
Magnets are brittle
Despite the nickel coating, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may shatter into hazardous fragments.
Respect the power
Exercise caution. Rare earth magnets act from a distance and snap with massive power, often faster than you can move away.
Finger safety
Danger of trauma: The pulling power is so immense that it can cause hematomas, pinching, and even bone fractures. Use thick gloves.
Keep away from electronics
Remember: rare earth magnets generate a field that confuses sensitive sensors. Maintain a separation from your phone, device, and GPS.
Swallowing risk
NdFeB magnets are not suitable for play. Accidental ingestion of multiple magnets may result in them pinching intestinal walls, which constitutes a severe health hazard and requires immediate surgery.
Mechanical processing
Powder created during cutting of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.
Allergic reactions
It is widely known that nickel (the usual finish) is a common allergen. If you have an allergy, avoid direct skin contact or select versions in plastic housing.
