Advantages and disadvantages of rare earth magnets.
Advantages
- They do not lose power, even during approximately ten years – the decrease in power is only ~1% (based on measurements),
- They retain their magnetic properties even under strong external field,
- Thanks to the elegant finish, the surface of Ni-Cu-Ni, gold-plated, or silver gives an modern appearance,
- Magnetic induction on the working part of the magnet turns out to be maximum,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling functioning at temperatures approaching 230°C and above...
- Possibility of custom modeling and optimizing to individual requirements,
- Versatile presence in high-tech industry – they are utilized in HDD drives, electromotive mechanisms, medical devices, as well as modern systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Weaknesses
- At strong impacts they can break, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- Due to limitations in producing threads and complex shapes in magnets, we recommend using cover - magnetic holder.
- Potential hazard to health – tiny shards of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. Additionally, small elements of these products are able to be problematic in diagnostics medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Maximum lifting force for a neodymium magnet – what contributes to it?
- on a base made of structural steel, optimally conducting the magnetic flux
- with a thickness of at least 10 mm
- with a plane perfectly flat
- with zero gap (no coatings)
- under vertical force direction (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
What influences lifting capacity in practice
- Distance – the presence of foreign body (paint, dirt, air) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 0.5 mm).
- Force direction – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Plate thickness – too thin plate does not accept the full field, causing part of the power to be lost to the other side.
- Material composition – not every steel attracts identically. High carbon content worsen the attraction effect.
- Base smoothness – the more even the surface, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
- Temperature – heating the magnet causes a temporary drop of force. Check the thermal limit for a given model.
Lifting capacity testing was conducted on a smooth plate of suitable thickness, under a perpendicular pulling force, whereas under parallel forces the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate lowers the lifting capacity.
Safety rules for work with neodymium magnets
Allergic reactions
Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If redness occurs, cease handling magnets and wear gloves.
GPS and phone interference
Note: neodymium magnets generate a field that confuses precision electronics. Maintain a separation from your phone, device, and GPS.
Cards and drives
Device Safety: Neodymium magnets can ruin data carriers and delicate electronics (heart implants, hearing aids, mechanical watches).
Handling guide
Before use, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.
Pinching danger
Big blocks can smash fingers in a fraction of a second. Do not place your hand between two attracting surfaces.
Danger to the youngest
Absolutely keep magnets away from children. Ingestion danger is high, and the consequences of magnets clamping inside the body are tragic.
Fragile material
Beware of splinters. Magnets can explode upon uncontrolled impact, launching shards into the air. We recommend safety glasses.
Implant safety
Life threat: Strong magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.
Fire risk
Dust produced during machining of magnets is self-igniting. Do not drill into magnets unless you are an expert.
Operating temperature
Avoid heat. NdFeB magnets are sensitive to temperature. If you need operation above 80°C, inquire about special high-temperature series (H, SH, UH).
