Pros as well as cons of rare earth magnets.
Advantages
- They retain magnetic properties for around ten years – the loss is just ~1% (based on simulations),
- Neodymium magnets are distinguished by remarkably resistant to demagnetization caused by external interference,
- Thanks to the shiny finish, the layer of Ni-Cu-Ni, gold, or silver gives an aesthetic appearance,
- Magnets exhibit excellent magnetic induction on the working surface,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling operation at temperatures approaching 230°C and above...
- In view of the potential of accurate shaping and adaptation to specialized requirements, magnetic components can be manufactured in a variety of geometric configurations, which increases their versatility,
- Versatile presence in innovative solutions – they are used in HDD drives, electromotive mechanisms, diagnostic systems, and technologically advanced constructions.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- To avoid cracks under impact, we recommend using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
- Neodymium magnets decrease their power 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
- They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited ability of making nuts in the magnet and complicated shapes - recommended is cover - magnet mounting.
- Health risk to health – tiny shards of magnets pose a threat, if swallowed, which gains importance in the context of child health protection. Additionally, tiny parts of these magnets can disrupt the diagnostic process medical when they are in the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Lifting parameters
Magnetic strength at its maximum – what affects it?
- with the application of a sheet made of low-carbon steel, guaranteeing maximum field concentration
- possessing a thickness of min. 10 mm to ensure full flux closure
- characterized by even structure
- with total lack of distance (no impurities)
- during detachment in a direction vertical to the plane
- at room temperature
Magnet lifting force in use – key factors
- Clearance – existence of foreign body (rust, tape, air) acts as an insulator, which lowers capacity steeply (even by 50% at 0.5 mm).
- Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
- Plate material – low-carbon steel gives the best results. Alloy admixtures lower magnetic permeability and lifting capacity.
- Base smoothness – the more even the plate, the larger the contact zone and higher the lifting capacity. Roughness creates an air distance.
- Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and in frost gain strength (up to a certain limit).
Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under shearing force the holding force is lower. Additionally, even a minimal clearance between the magnet and the plate reduces the holding force.
Safe handling of neodymium magnets
Sensitization to coating
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If redness appears, cease working with magnets and wear gloves.
Do not give to children
Absolutely store magnets out of reach of children. Choking hazard is significant, and the consequences of magnets clamping inside the body are fatal.
Mechanical processing
Mechanical processing of neodymium magnets carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Impact on smartphones
GPS units and smartphones are highly susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can permanently damage the sensors in your phone.
Conscious usage
Before starting, read the rules. Sudden snapping can break the magnet or injure your hand. Be predictive.
Demagnetization risk
Regular neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. Damage is permanent.
Pacemakers
People with a ICD must maintain an large gap from magnets. The magnetism can stop the operation of the implant.
Beware of splinters
Watch out for shards. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. We recommend safety glasses.
Crushing force
Watch your fingers. Two powerful magnets will snap together immediately with a force of massive weight, destroying anything in their path. Be careful!
Electronic hazard
Avoid bringing magnets close to a wallet, computer, or TV. The magnetic field can destroy these devices and erase data from cards.
