Advantages and disadvantages of rare earth magnets.
Strengths
- They have stable power, and over nearly 10 years their attraction force decreases symbolically – ~1% (according to theory),
- They retain their magnetic properties even under close interference source,
- The use of an metallic coating of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- Magnets have excellent magnetic induction on the surface,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures approaching 230°C and above...
- Thanks to the potential of precise shaping and adaptation to custom requirements, neodymium magnets can be manufactured in a variety of shapes and sizes, which amplifies use scope,
- Fundamental importance in high-tech industry – they are utilized in HDD drives, brushless drives, medical equipment, and modern systems.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Disadvantages
- To avoid cracks under impact, we recommend using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
- NdFeB magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- Due to limitations in creating nuts and complex forms in magnets, we propose using casing - magnetic mechanism.
- Potential hazard resulting from small fragments of magnets pose a threat, in case of ingestion, which becomes key in the context of child safety. It is also worth noting that small elements of these magnets are able to disrupt the diagnostic process medical when they are in the body.
- With large orders the cost of neodymium magnets can be a barrier,
Pull force analysis
Maximum holding power of the magnet – what contributes to it?
- on a block made of structural steel, optimally conducting the magnetic flux
- with a thickness no less than 10 mm
- with an ideally smooth touching surface
- without any air gap between the magnet and steel
- under axial force direction (90-degree angle)
- at room temperature
What influences lifting capacity in practice
- Gap (betwixt the magnet and the metal), as even a microscopic clearance (e.g. 0.5 mm) results in a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Base massiveness – too thin sheet causes magnetic saturation, causing part of the power to be lost to the other side.
- Plate material – low-carbon steel attracts best. Alloy steels decrease magnetic permeability and holding force.
- Surface quality – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
- Thermal conditions – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).
Lifting capacity was determined by applying a polished steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under attempts to slide the magnet the holding force is lower. Additionally, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.
Safe handling of neodymium magnets
GPS and phone interference
Remember: rare earth magnets produce a field that confuses sensitive sensors. Keep a safe distance from your mobile, tablet, and navigation systems.
Permanent damage
Keep cool. Neodymium magnets are sensitive to temperature. If you need resistance above 80°C, inquire about HT versions (H, SH, UH).
Hand protection
Protect your hands. Two powerful magnets will join immediately with a force of massive weight, destroying anything in their path. Be careful!
Health Danger
For implant holders: Powerful magnets affect electronics. Maintain minimum 30 cm distance or request help to work with the magnets.
Immense force
Handle with care. Neodymium magnets act from a distance and snap with huge force, often faster than you can react.
Product not for children
Adult use only. Small elements pose a choking risk, leading to intestinal necrosis. Keep out of reach of children and animals.
Dust is flammable
Mechanical processing of neodymium magnets carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Risk of cracking
NdFeB magnets are ceramic materials, meaning they are prone to chipping. Impact of two magnets will cause them shattering into shards.
Nickel coating and allergies
Studies show that nickel (standard magnet coating) is a strong allergen. If you have an allergy, prevent touching magnets with bare hands or select versions in plastic housing.
Protect data
Avoid bringing magnets near a wallet, laptop, or TV. The magnetic field can destroy these devices and erase data from cards.
