Advantages as well as disadvantages of neodymium magnets.
Advantages
- Their power is maintained, and after around 10 years it decreases only by ~1% (according to research),
- They do not lose their magnetic properties even under strong external field,
- The use of an aesthetic layer of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Neodymium magnets create maximum magnetic induction on a contact point, which ensures high operational effectiveness,
- Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
- Possibility of precise forming as well as optimizing to specific applications,
- Wide application in high-tech industry – they are utilized in computer drives, electric drive systems, medical equipment, and complex engineering applications.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Limitations
- At very strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- Neodymium magnets decrease 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 stability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- Limited possibility of creating threads in the magnet and complicated forms - preferred is cover - magnet mounting.
- Possible danger related to microscopic parts of magnets are risky, in case of ingestion, which gains importance in the context of child safety. Furthermore, small components of these devices are able to complicate diagnosis medical after entering the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Maximum magnetic pulling force – what contributes to it?
- on a base made of mild steel, effectively closing the magnetic field
- possessing a massiveness of min. 10 mm to avoid saturation
- characterized by even structure
- under conditions of ideal adhesion (metal-to-metal)
- during pulling in a direction vertical to the plane
- at conditions approx. 20°C
What influences lifting capacity in practice
- Clearance – the presence of any layer (rust, dirt, gap) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Force direction – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Metal type – not every steel attracts identically. High carbon content weaken the attraction effect.
- Plate texture – smooth surfaces ensure maximum contact, which increases field saturation. Uneven metal weaken the grip.
- Temperature influence – hot environment reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under attempts to slide the magnet the load capacity is reduced by as much as 75%. In addition, even a slight gap between the magnet’s surface and the plate reduces the load capacity.
Safe handling of neodymium magnets
Magnets are brittle
Neodymium magnets are ceramic materials, meaning they are fragile like glass. Collision of two magnets will cause them shattering into shards.
Swallowing risk
Adult use only. Small elements can be swallowed, causing severe trauma. Store out of reach of children and animals.
Immense force
Handle with care. Rare earth magnets act from a distance and connect with massive power, often quicker than you can move away.
Phone sensors
Note: rare earth magnets generate a field that confuses sensitive sensors. Maintain a safe distance from your mobile, tablet, and navigation systems.
Protect data
Equipment safety: Strong magnets can damage payment cards and delicate electronics (pacemakers, medical aids, mechanical watches).
Flammability
Powder generated during grinding of magnets is flammable. Avoid drilling into magnets unless you are an expert.
Sensitization to coating
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If skin irritation occurs, immediately stop handling magnets and use protective gear.
Crushing force
Pinching hazard: The attraction force is so immense that it can result in hematomas, crushing, and broken bones. Protective gloves are recommended.
Power loss in heat
Standard neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. This process is irreversible.
Implant safety
Patients with a heart stimulator should keep an absolute distance from magnets. The magnetism can disrupt the functioning of the life-saving device.
