Advantages and disadvantages of Nd2Fe14B magnets.
Strengths
- They virtually do not lose power, because even after ten years the performance loss is only ~1% (in laboratory conditions),
- Magnets effectively resist against demagnetization caused by ambient magnetic noise,
- By using a reflective layer of silver, the element acquires an modern look,
- Magnets are distinguished by maximum magnetic induction on the surface,
- Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to modularity in constructing and the ability to adapt to complex applications,
- Huge importance in future technologies – they are commonly used in computer drives, electric drive systems, medical devices, and technologically advanced constructions.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Disadvantages
- To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
- Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
- We recommend cover - magnetic holder, due to difficulties in realizing threads inside the magnet and complicated forms.
- Potential hazard to health – tiny shards of magnets pose a threat, if swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, small components of these devices can complicate diagnosis medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Pull force analysis
Magnetic strength at its maximum – what affects it?
- on a plate made of mild steel, perfectly concentrating the magnetic field
- whose thickness is min. 10 mm
- with a surface perfectly flat
- under conditions of no distance (metal-to-metal)
- during detachment in a direction perpendicular to the plane
- at conditions approx. 20°C
Practical lifting capacity: influencing factors
- Gap between surfaces – even a fraction of a millimeter of separation (caused e.g. by veneer or dirt) diminishes the pulling force, often by half at just 0.5 mm.
- Loading method – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet exhibits significantly lower power (typically approx. 20-30% of nominal force).
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Material type – ideal substrate is pure iron steel. Hardened steels may attract less.
- Surface finish – full contact is obtained only on smooth steel. Any scratches and bumps create air cushions, reducing force.
- Temperature influence – high temperature weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity testing was performed on a smooth plate of suitable thickness, under perpendicular forces, in contrast under attempts to slide the magnet the load capacity is reduced by as much as fivefold. In addition, even a minimal clearance between the magnet’s surface and the plate lowers the holding force.
Warnings
Keep away from electronics
Navigation devices and mobile phones are highly sensitive to magnetic fields. Direct contact with a powerful NdFeB magnet can ruin the internal compass in your phone.
Do not drill into magnets
Mechanical processing of NdFeB material poses a fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Maximum temperature
Avoid heat. Neodymium magnets are susceptible to heat. If you need operation above 80°C, ask us about HT versions (H, SH, UH).
Respect the power
Exercise caution. Neodymium magnets attract from a distance and snap with massive power, often quicker than you can react.
Danger to the youngest
Strictly keep magnets out of reach of children. Choking hazard is high, and the effects of magnets connecting inside the body are tragic.
Bone fractures
Large magnets can smash fingers in a fraction of a second. Under no circumstances put your hand between two strong magnets.
ICD Warning
Life threat: Strong magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.
Shattering risk
Protect your eyes. Magnets can explode upon uncontrolled impact, launching shards into the air. Eye protection is mandatory.
Skin irritation risks
Certain individuals suffer from a hypersensitivity to nickel, which is the standard coating for neodymium magnets. Extended handling may cause a rash. We strongly advise wear protective gloves.
Safe distance
Very strong magnetic fields can destroy records on credit cards, hard drives, and other magnetic media. Keep a distance of min. 10 cm.
