Advantages and disadvantages of rare earth magnets.
Advantages
- They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
- They do not lose their magnetic properties even under strong external field,
- A magnet with a shiny silver surface has an effective appearance,
- Neodymium magnets deliver maximum magnetic induction on a contact point, which ensures high operational effectiveness,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
- Thanks to flexibility in designing and the ability to modify to client solutions,
- Wide application in future technologies – they find application in magnetic memories, drive modules, diagnostic systems, also modern systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which allows their use in small systems
Cons
- At strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- We warn that neodymium magnets can reduce their power 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 resistant to moisture, in case of application outdoors
- Limited ability of producing threads in the magnet and complex forms - preferred is cover - mounting mechanism.
- Health risk to health – tiny shards of magnets are risky, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small elements of these magnets are able to be problematic in diagnostics medical in case of swallowing.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities
Pull force analysis
Highest magnetic holding force – what affects it?
- on a base made of structural steel, optimally conducting the magnetic field
- possessing a massiveness of at least 10 mm to ensure full flux closure
- with a plane cleaned and smooth
- under conditions of no distance (surface-to-surface)
- under axial force vector (90-degree angle)
- in neutral thermal conditions
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 varnish or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
- Load vector – highest force is obtained only during pulling at a 90° angle. The shear force of the magnet along the plate is typically many times smaller (approx. 1/5 of the lifting capacity).
- Substrate thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
- Chemical composition of the base – mild steel gives the best results. Alloy steels decrease magnetic permeability and holding force.
- Base smoothness – the more even the surface, the better the adhesion and stronger the hold. Roughness acts like micro-gaps.
- Thermal conditions – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).
Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under shearing force the load capacity is reduced by as much as 75%. In addition, even a slight gap between the magnet’s surface and the plate lowers the lifting capacity.
Safe handling of NdFeB magnets
Beware of splinters
Neodymium magnets are sintered ceramics, meaning they are prone to chipping. Collision of two magnets will cause them breaking into small pieces.
Safe operation
Before use, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Be predictive.
Medical implants
For implant holders: Strong magnetic fields disrupt medical devices. Maintain minimum 30 cm distance or ask another person to work with the magnets.
Demagnetization risk
Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will destroy its magnetic structure and pulling force.
Combustion hazard
Powder produced during cutting of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
Warning for allergy sufferers
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If an allergic reaction happens, immediately stop handling magnets and use protective gear.
Serious injuries
Large magnets can smash fingers instantly. Under no circumstances place your hand betwixt two attracting surfaces.
Protect data
Very strong magnetic fields can destroy records on payment cards, HDDs, and other magnetic media. Keep a distance of at least 10 cm.
Precision electronics
Navigation devices and smartphones are highly sensitive to magnetic fields. Close proximity with a strong magnet can ruin the internal compass in your phone.
Adults only
Neodymium magnets are not suitable for play. Accidental ingestion of multiple magnets may result in them attracting across intestines, which constitutes a direct threat to life and requires urgent medical intervention.
