Pros and cons of neodymium magnets.
Pros
- They do not lose strength, even during around 10 years – the drop in strength is only ~1% (theoretically),
- Neodymium magnets are exceptionally resistant to demagnetization caused by external field sources,
- The use of an elegant coating of noble metals (nickel, gold, silver) causes the element to look better,
- The surface of neodymium magnets generates a strong magnetic field – this is a key feature,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling action at temperatures approaching 230°C and above...
- Possibility of individual modeling and adjusting to complex applications,
- Fundamental importance in electronics industry – they are commonly used in HDD drives, electric drive systems, diagnostic systems, also modern systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Limitations
- To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 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 and corrosion.
- Due to limitations in producing nuts and complicated shapes in magnets, we propose using a housing - magnetic mechanism.
- Potential hazard related to microscopic parts of magnets pose a threat, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, small components of these products can be problematic in diagnostics medical after entering the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Pull force analysis
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- with the application of a sheet made of special test steel, guaranteeing maximum field concentration
- possessing a massiveness of min. 10 mm to ensure full flux closure
- characterized by smoothness
- under conditions of gap-free contact (surface-to-surface)
- under vertical force direction (90-degree angle)
- at room temperature
What influences lifting capacity in practice
- Distance (between the magnet and the metal), because even a microscopic clearance (e.g. 0.5 mm) leads to a decrease in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Material composition – different alloys attracts identically. High carbon content weaken the interaction with the magnet.
- Plate texture – ground elements guarantee perfect abutment, which improves field saturation. Uneven metal weaken the grip.
- Thermal factor – high temperature reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity was assessed with the use of a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, whereas under parallel forces the holding force is lower. Additionally, even a small distance between the magnet and the plate decreases the lifting capacity.
Warnings
Respect the power
Handle magnets with awareness. Their immense force can surprise even experienced users. Plan your moves and respect their force.
Fragile material
Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Protect data
Device Safety: Strong magnets can damage payment cards and delicate electronics (heart implants, medical aids, mechanical watches).
Swallowing risk
Only for adults. Small elements pose a choking risk, causing intestinal necrosis. Keep out of reach of kids and pets.
Dust is flammable
Mechanical processing of NdFeB material carries a risk of fire hazard. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Allergic reactions
Studies show that the nickel plating (standard magnet coating) is a potent allergen. If you have an allergy, avoid direct skin contact or choose coated magnets.
Warning for heart patients
Warning for patients: Strong magnetic fields affect electronics. Maintain at least 30 cm distance or request help to handle the magnets.
Maximum temperature
Regular neodymium magnets (N-type) lose power when the temperature goes above 80°C. The loss of strength is permanent.
Precision electronics
Note: neodymium magnets generate a field that interferes with sensitive sensors. Keep a safe distance from your phone, tablet, and GPS.
Pinching danger
Risk of injury: The attraction force is so great that it can cause blood blisters, pinching, and broken bones. Protective gloves are recommended.
