Advantages and disadvantages of neodymium magnets.
Advantages
- Their magnetic field is durable, and after approximately ten years it decreases only by ~1% (according to research),
- They show high resistance to demagnetization induced by presence of other magnetic fields,
- Thanks to the smooth finish, the coating of Ni-Cu-Ni, gold, or silver gives an visually attractive appearance,
- The surface of neodymium magnets generates a powerful magnetic field – this is a key feature,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Due to the potential of flexible molding and customization to individualized solutions, magnetic components can be manufactured in a variety of geometric configurations, which amplifies use scope,
- Huge importance in high-tech industry – they are utilized in data components, electric drive systems, medical devices, and industrial machines.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Limitations
- At strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets lose their force 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
- 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, when using outdoors
- Due to limitations in realizing threads and complicated shapes in magnets, we propose using a housing - magnetic mount.
- Potential hazard to health – tiny shards of magnets pose a threat, in case of ingestion, which becomes key in the context of child health protection. Additionally, small elements of these devices can be problematic in diagnostics medical when they are in the body.
- With budget limitations the cost of neodymium magnets is economically unviable,
Lifting parameters
Maximum lifting force for a neodymium magnet – what contributes to it?
- with the contact of a sheet made of low-carbon steel, ensuring maximum field concentration
- with a thickness no less than 10 mm
- with a surface cleaned and smooth
- under conditions of gap-free contact (metal-to-metal)
- for force applied at a right angle (in the magnet axis)
- in temp. approx. 20°C
What influences lifting capacity in practice
- Air gap (betwixt the magnet and the plate), because even a tiny distance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
- Force direction – remember that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
- Metal type – not every steel attracts identically. High carbon content weaken the attraction effect.
- Surface finish – ideal contact is possible only on smooth steel. Rough texture create air cushions, reducing force.
- Temperature – heating the magnet results in weakening of induction. Check the maximum operating temperature for a given model.
Lifting capacity testing was performed on a smooth plate of optimal thickness, under a perpendicular pulling force, whereas under shearing force the holding force is lower. In addition, even a minimal clearance between the magnet’s surface and the plate lowers the load capacity.
Safety rules for work with neodymium magnets
Allergic reactions
Certain individuals experience a contact allergy to Ni, which is the standard coating for NdFeB magnets. Frequent touching might lead to skin redness. We recommend wear protective gloves.
GPS Danger
A strong magnetic field interferes with the functioning of compasses in phones and GPS navigation. Maintain magnets near a smartphone to avoid damaging the sensors.
Medical implants
Individuals with a ICD should maintain an large gap from magnets. The magnetism can disrupt the functioning of the implant.
Bone fractures
Risk of injury: The attraction force is so immense that it can cause blood blisters, pinching, and even bone fractures. Use thick gloves.
Heat sensitivity
Avoid heat. NdFeB magnets are sensitive to heat. If you need resistance above 80°C, look for HT versions (H, SH, UH).
Adults only
Strictly store magnets out of reach of children. Risk of swallowing is high, and the effects of magnets clamping inside the body are fatal.
Fire warning
Mechanical processing of neodymium magnets poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Threat to electronics
Device Safety: Strong magnets can ruin payment cards and delicate electronics (heart implants, hearing aids, mechanical watches).
Do not underestimate power
Handle magnets consciously. Their immense force can surprise even professionals. Be vigilant and do not underestimate their force.
Fragile material
Despite metallic appearance, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may crumble into hazardous fragments.
