Other proposals
Strengths as well as weaknesses of neodymium magnets.
Strengths
- They have constant strength, and over around 10 years their performance decreases symbolically – ~1% (according to theory),
- Neodymium magnets remain highly resistant to magnetic field loss caused by external field sources,
- The use of an refined coating of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Magnetic induction on the surface of the magnet turns out to be impressive,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for operation at temperatures approaching 230°C and above...
- Thanks to versatility in designing and the capacity to adapt to specific needs,
- Universal use in high-tech industry – they are utilized in mass storage devices, electric drive systems, precision medical tools, as well as modern systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which allows their use in miniature devices
Limitations
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a special holder, which not only protects them against impacts but also raises their durability
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop 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 extremely resistant to heat
- 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
- Due to limitations in creating threads and complicated shapes in magnets, we recommend using cover - magnetic mechanism.
- Health risk to health – tiny shards of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child safety. Furthermore, small components of these devices can disrupt the diagnostic process medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Pull force analysis
Detachment force of the magnet in optimal conditions – what contributes to it?
- on a base made of structural steel, optimally conducting the magnetic field
- with a cross-section no less than 10 mm
- with a surface cleaned and smooth
- under conditions of ideal adhesion (metal-to-metal)
- during pulling in a direction perpendicular to the mounting surface
- at room temperature
Magnet lifting force in use – key factors
- Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by varnish or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
- Force direction – declared lifting capacity refers to pulling vertically. When slipping, the magnet exhibits significantly lower power (often approx. 20-30% of maximum force).
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
- Steel grade – ideal substrate is high-permeability steel. Stainless steels may generate lower lifting capacity.
- Surface quality – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Roughness acts like micro-gaps.
- Operating temperature – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity testing was conducted on a smooth plate of optimal thickness, under perpendicular forces, however under shearing force the holding force is lower. In addition, even a minimal clearance between the magnet and the plate decreases the holding force.
Safety rules for work with NdFeB magnets
Do not underestimate power
Handle with care. Neodymium magnets act from a distance and connect with huge force, often faster than you can move away.
Warning for allergy sufferers
Nickel alert: The Ni-Cu-Ni coating contains nickel. If skin irritation happens, immediately stop handling magnets and use protective gear.
Material brittleness
Protect your eyes. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. Eye protection is mandatory.
Medical interference
Life threat: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.
Keep away from computers
Very strong magnetic fields can destroy records on payment cards, hard drives, and storage devices. Keep a distance of min. 10 cm.
Dust is flammable
Drilling and cutting of neodymium magnets carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Maximum temperature
Avoid heat. Neodymium magnets are sensitive to heat. If you need resistance above 80°C, ask us about HT versions (H, SH, UH).
Magnetic interference
Navigation devices and mobile phones are extremely sensitive to magnetism. Direct contact with a powerful NdFeB magnet can decalibrate the internal compass in your phone.
Crushing force
Large magnets can break fingers in a fraction of a second. Never place your hand between two strong magnets.
Keep away from children
Adult use only. Tiny parts can be swallowed, causing serious injuries. Store out of reach of kids and pets.
