Pros and cons of neodymium magnets.
Strengths
- They have stable power, and over around ten years their performance decreases symbolically – ~1% (in testing),
- They show high resistance to demagnetization induced by external field influence,
- The use of an metallic coating of noble metals (nickel, gold, silver) causes the element to present itself better,
- Magnets are characterized by very high magnetic induction on the working surface,
- 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...
- Thanks to flexibility in shaping and the capacity to modify to specific needs,
- Significant place in innovative solutions – they serve a role in magnetic memories, electric drive systems, medical devices, as well as complex engineering applications.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Cons
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a steel housing, which not only protects them against impacts but also increases their durability
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- We suggest casing - magnetic holder, due to difficulties in realizing threads inside the magnet and complex shapes.
- Potential hazard related to microscopic parts of magnets are risky, in case of ingestion, which is particularly important in the context of child safety. It is also worth noting that small components of these devices are able to be problematic in diagnostics 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
Pull force analysis
Maximum holding power of the magnet – what it depends on?
- with the application of a yoke made of special test steel, guaranteeing maximum field concentration
- with a thickness no less than 10 mm
- with an ideally smooth contact surface
- under conditions of ideal adhesion (metal-to-metal)
- under axial force direction (90-degree angle)
- in stable room temperature
Determinants of lifting force in real conditions
- Space between surfaces – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
- Load vector – highest force is obtained only during perpendicular pulling. The shear force of the magnet along the surface is usually several times smaller (approx. 1/5 of the lifting capacity).
- Substrate thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Material composition – not every steel attracts identically. Alloy additives worsen the interaction with the magnet.
- Surface finish – full contact is possible only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
- Operating temperature – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity was measured with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular pulling force, in contrast under parallel forces the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate lowers the holding force.
Safe handling of NdFeB magnets
Heat warning
Standard neodymium magnets (grade N) lose magnetization when the temperature goes above 80°C. The loss of strength is permanent.
Conscious usage
Be careful. Rare earth magnets attract from a long distance and connect with massive power, often faster than you can react.
Avoid contact if allergic
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction happens, cease handling magnets and wear gloves.
Choking Hazard
Adult use only. Small elements pose a choking risk, leading to severe trauma. Keep away from kids and pets.
Protective goggles
Despite metallic appearance, the material is delicate and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
Flammability
Fire warning: Neodymium dust is highly flammable. Do not process magnets in home conditions as this risks ignition.
Electronic hazard
Data protection: Neodymium magnets can damage payment cards and sensitive devices (pacemakers, medical aids, timepieces).
Implant safety
For implant holders: Strong magnetic fields affect medical devices. Maintain at least 30 cm distance or ask another person to handle the magnets.
Finger safety
Danger of trauma: The attraction force is so great that it can result in blood blisters, pinching, and broken bones. Protective gloves are recommended.
Keep away from electronics
Note: rare earth magnets produce a field that interferes with sensitive sensors. Maintain a safe distance from your mobile, device, and GPS.
