Advantages and disadvantages of Nd2Fe14B magnets.
Benefits
- They virtually do not lose strength, because even after ten years the performance loss is only ~1% (based on calculations),
- They retain their magnetic properties even under strong external field,
- A magnet with a metallic silver surface looks better,
- They feature high magnetic induction at the operating surface, which improves attraction properties,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Thanks to freedom in forming and the ability to customize to unusual requirements,
- Universal use in future technologies – they are utilized in hard drives, motor assemblies, medical devices, and industrial machines.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Disadvantages
- To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
- Neodymium magnets decrease 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 stability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- We suggest a housing - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complicated forms.
- Potential hazard related to microscopic parts of magnets pose a threat, if swallowed, which becomes key in the context of child safety. Additionally, tiny parts of these magnets can disrupt the diagnostic process medical when they are in the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities
Lifting parameters
Maximum magnetic pulling force – what affects it?
- using a base made of high-permeability steel, acting as a magnetic yoke
- whose thickness is min. 10 mm
- characterized by lack of roughness
- with direct contact (no paint)
- during detachment in a direction perpendicular to the plane
- at ambient temperature room level
Magnet lifting force in use – key factors
- Distance (betwixt the magnet and the metal), as even a tiny distance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to varnish, corrosion or dirt).
- 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 smaller (approx. 1/5 of the lifting capacity).
- Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
- Steel grade – the best choice is high-permeability steel. Cast iron may generate lower lifting capacity.
- Surface finish – full contact is obtained only on polished steel. Rough texture create air cushions, weakening the magnet.
- Temperature influence – high temperature weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under parallel forces the holding force is lower. Moreover, even a small distance between the magnet’s surface and the plate reduces the load capacity.
Precautions when working with neodymium magnets
Heat sensitivity
Keep cool. Neodymium magnets are susceptible to heat. If you need operation above 80°C, inquire about special high-temperature series (H, SH, UH).
Powerful field
Exercise caution. Neodymium magnets act from a distance and snap with massive power, often quicker than you can move away.
Magnets are brittle
Despite metallic appearance, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.
Do not drill into magnets
Machining of neodymium magnets poses a fire hazard. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
No play value
Only for adults. Small elements can be swallowed, causing serious injuries. Store away from kids and pets.
Electronic hazard
Powerful magnetic fields can destroy records on credit cards, hard drives, and other magnetic media. Keep a distance of min. 10 cm.
Physical harm
Danger of trauma: The attraction force is so great that it can result in blood blisters, pinching, and broken bones. Protective gloves are recommended.
Precision electronics
Navigation devices and mobile phones are extremely susceptible to magnetic fields. Direct contact with a powerful NdFeB magnet can ruin the internal compass in your phone.
Danger to pacemakers
Patients with a pacemaker should maintain an large gap from magnets. The magnetism can interfere with the operation of the implant.
Metal Allergy
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If skin irritation occurs, cease handling magnets and wear gloves.
