Pros and cons of neodymium magnets.
Pros
- They do not lose strength, even over approximately ten years – the decrease in lifting capacity is only ~1% (according to tests),
- Neodymium magnets remain extremely resistant to magnetic field loss caused by external interference,
- Thanks to the shimmering finish, the layer of Ni-Cu-Ni, gold, or silver-plated gives an aesthetic appearance,
- Magnets possess extremely high magnetic induction on the active area,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Thanks to versatility in forming and the ability to adapt to client solutions,
- Universal use in modern industrial fields – they serve a role in data components, electromotive mechanisms, medical equipment, also technologically advanced constructions.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Limitations
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
- 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 stability even at temperatures up to 230°C
- They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited ability of making nuts in the magnet and complex forms - recommended is cover - magnetic holder.
- Health risk related to microscopic parts of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child safety. Additionally, tiny parts of these devices can disrupt the diagnostic process 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
Lifting parameters
Maximum holding power of the magnet – what it depends on?
- with the use of a sheet made of low-carbon steel, guaranteeing full magnetic saturation
- whose thickness reaches at least 10 mm
- with a surface free of scratches
- under conditions of no distance (surface-to-surface)
- under perpendicular application of breakaway force (90-degree angle)
- in temp. approx. 20°C
Impact of factors on magnetic holding capacity in practice
- Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by veneer or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
- Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Base massiveness – too thin steel does not accept the full field, causing part of the flux to be escaped to the other side.
- Metal type – different alloys reacts the same. High carbon content worsen the interaction with the magnet.
- Plate texture – smooth surfaces ensure maximum contact, which improves field saturation. Uneven metal reduce efficiency.
- Heat – neodymium magnets have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures gain strength (up to a certain limit).
Lifting capacity testing was conducted on a smooth plate of suitable thickness, under perpendicular forces, however under parallel forces the holding force is lower. Moreover, even a slight gap between the magnet and the plate reduces the holding force.
Precautions when working with NdFeB magnets
Choking Hazard
NdFeB magnets are not intended for children. Accidental ingestion of several magnets may result in them pinching intestinal walls, which constitutes a critical condition and requires immediate surgery.
Keep away from computers
Very strong magnetic fields can corrupt files on payment cards, HDDs, and storage devices. Stay away of min. 10 cm.
Maximum temperature
Monitor thermal conditions. Exposing the magnet to high heat will ruin its properties and strength.
Conscious usage
Use magnets consciously. Their powerful strength can surprise even professionals. Be vigilant and do not underestimate their power.
Metal Allergy
Nickel alert: The nickel-copper-nickel coating consists of nickel. If skin irritation appears, immediately stop working with magnets and wear gloves.
Implant safety
Warning for patients: Powerful magnets disrupt medical devices. Keep minimum 30 cm distance or request help to handle the magnets.
GPS and phone interference
Note: rare earth magnets generate a field that interferes with precision electronics. Keep a separation from your phone, tablet, and GPS.
Dust explosion hazard
Machining of NdFeB material poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Magnets are brittle
Despite metallic appearance, the material is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Physical harm
Big blocks can crush fingers instantly. Never put your hand betwixt two strong magnets.
