Pros and cons of neodymium magnets.
Pros
- They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (in laboratory conditions),
- Magnets effectively defend themselves against loss of magnetization caused by foreign field sources,
- In other words, due to the reflective surface of nickel, the element gains visual value,
- The surface of neodymium magnets generates a maximum magnetic field – this is a distinguishing feature,
- 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...
- Possibility of precise forming as well as modifying to concrete conditions,
- Wide application in electronics industry – they serve a role in magnetic memories, electric drive systems, precision medical tools, as well as complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which allows their use in miniature devices
Disadvantages
- To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
- Neodymium magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (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 very resistant to heat
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
- We suggest casing - magnetic holder, due to difficulties in realizing nuts inside the magnet and complex shapes.
- Health risk to health – tiny shards of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child health protection. Furthermore, small elements of these magnets are able to disrupt the diagnostic process medical when they are in the body.
- Due to neodymium price, their price exceeds standard values,
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- on a base made of structural steel, perfectly concentrating the magnetic flux
- whose transverse dimension is min. 10 mm
- with a plane cleaned and smooth
- without the slightest air gap between the magnet and steel
- during pulling in a direction perpendicular to the plane
- at conditions approx. 20°C
Lifting capacity in real conditions – factors
- Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Direction of force – highest force is obtained only during perpendicular pulling. The shear force of the magnet along the surface is typically many times lower (approx. 1/5 of the lifting capacity).
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
- Steel grade – ideal substrate is pure iron steel. Stainless steels may have worse magnetic properties.
- Surface structure – the more even the surface, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
- Temperature influence – hot environment weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.
Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under parallel forces the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate lowers the holding force.
Safe handling of neodymium magnets
Maximum temperature
Do not overheat. Neodymium magnets are susceptible to heat. If you need resistance above 80°C, ask us about HT versions (H, SH, UH).
Adults only
Always keep magnets away from children. Ingestion danger is significant, and the consequences of magnets clamping inside the body are very dangerous.
Powerful field
Before use, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Be predictive.
Data carriers
Device Safety: Neodymium magnets can damage data carriers and delicate electronics (heart implants, medical aids, mechanical watches).
Bodily injuries
Mind your fingers. Two large magnets will snap together immediately with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!
Magnets are brittle
Protect your eyes. Magnets can explode upon uncontrolled impact, launching shards into the air. We recommend safety glasses.
Allergy Warning
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If an allergic reaction happens, cease handling magnets and use protective gear.
Impact on smartphones
Note: neodymium magnets generate a field that confuses sensitive sensors. Maintain a separation from your phone, tablet, and GPS.
Machining danger
Fire warning: Rare earth powder is highly flammable. Avoid machining magnets without safety gear as this may cause fire.
Warning for heart patients
Individuals with a heart stimulator must keep an safe separation from magnets. The magnetism can interfere with the functioning of the implant.
