Advantages as well as disadvantages of neodymium magnets.
Strengths
- They have unchanged lifting capacity, and over more than 10 years their performance decreases symbolically – ~1% (in testing),
- Magnets very well defend themselves against loss of magnetization caused by foreign field sources,
- A magnet with a metallic silver surface has an effective appearance,
- Magnets have extremely high magnetic induction on the outer layer,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Possibility of accurate modeling and optimizing to defined applications,
- Versatile presence in high-tech industry – they are used in HDD drives, motor assemblies, advanced medical instruments, and other advanced devices.
- Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a special holder, which not only protects them against impacts but also increases their durability
- Neodymium magnets lose 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 durability even at temperatures up to 230°C
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
- Limited ability of making threads in the magnet and complicated shapes - preferred is cover - mounting mechanism.
- Health risk to health – tiny shards of magnets are risky, in case of ingestion, which gains importance in the context of child safety. Furthermore, small components of these magnets can 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 increases costs of application in large quantities
Pull force analysis
Maximum holding power of the magnet – what contributes to it?
- with the contact of a sheet made of special test steel, guaranteeing maximum field concentration
- whose thickness equals approx. 10 mm
- with an ground touching surface
- without any insulating layer between the magnet and steel
- during pulling in a direction vertical to the plane
- at standard ambient temperature
Determinants of lifting force in real conditions
- Air gap (betwixt the magnet and the plate), because even a microscopic clearance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to varnish, corrosion or dirt).
- Force direction – declared lifting capacity refers to pulling vertically. When slipping, the magnet exhibits much less (often approx. 20-30% of nominal force).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
- Metal type – different alloys attracts identically. High carbon content weaken the interaction with the magnet.
- Plate texture – smooth surfaces guarantee perfect abutment, which increases force. Rough surfaces reduce efficiency.
- Heat – NdFeB sinters have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures gain strength (up to a certain limit).
Lifting capacity was measured by applying a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular pulling force, in contrast under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the holding force.
Safe handling of NdFeB magnets
Sensitization to coating
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction occurs, immediately stop working with magnets and use protective gear.
Implant safety
People with a heart stimulator should keep an absolute distance from magnets. The magnetic field can stop the operation of the implant.
Impact on smartphones
A strong magnetic field negatively affects the operation of magnetometers in phones and GPS navigation. Do not bring magnets close to a device to avoid breaking the sensors.
Crushing force
Pinching hazard: The pulling power is so immense that it can cause hematomas, pinching, and broken bones. Protective gloves are recommended.
Protect data
Intense magnetic fields can corrupt files on payment cards, HDDs, and storage devices. Stay away of min. 10 cm.
Do not drill into magnets
Fire hazard: Rare earth powder is explosive. Do not process magnets in home conditions as this risks ignition.
Do not underestimate power
Handle magnets consciously. Their powerful strength can surprise even professionals. Be vigilant and respect their power.
Beware of splinters
Protect your eyes. Magnets can explode upon violent connection, ejecting shards into the air. We recommend safety glasses.
Swallowing risk
Absolutely keep magnets out of reach of children. Ingestion danger is high, and the effects of magnets clamping inside the body are life-threatening.
Power loss in heat
Avoid heat. Neodymium magnets are sensitive to heat. If you require operation above 80°C, ask us about HT versions (H, SH, UH).
