Pros as well as cons of neodymium magnets.
Strengths
- They have constant strength, and over around 10 years their performance decreases symbolically – ~1% (according to theory),
- They feature excellent resistance to magnetic field loss when exposed to external fields,
- A magnet with a smooth silver surface is more attractive,
- They show high magnetic induction at the operating surface, making them more effective,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Considering the option of free molding and customization to specialized needs, neodymium magnets can be produced in a variety of forms and dimensions, which increases their versatility,
- Wide application in modern industrial fields – they find application in HDD drives, drive modules, diagnostic systems, as well as other advanced devices.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Limitations
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also improves its resistance to damage
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Limited possibility of making nuts in the magnet and complex shapes - preferred is a housing - magnet mounting.
- Health risk to health – tiny shards of magnets are risky, if swallowed, which becomes key in the context of child safety. It is also worth noting that small elements of these products are able to be problematic in diagnostics medical when they are in the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities
Holding force characteristics
Maximum lifting force for a neodymium magnet – what affects it?
- with the contact of a sheet made of special test steel, guaranteeing full magnetic saturation
- whose thickness is min. 10 mm
- with an ideally smooth contact surface
- without the slightest air gap between the magnet and steel
- under vertical force direction (90-degree angle)
- at standard ambient temperature
Practical lifting capacity: influencing factors
- Gap between surfaces – every millimeter of distance (caused e.g. by veneer or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
- Material type – the best choice is high-permeability steel. Stainless steels may generate lower lifting capacity.
- Smoothness – ideal contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Temperature – heating the magnet causes a temporary drop of induction. Check the thermal limit for a given model.
Lifting capacity was determined using a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, however under shearing force the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate lowers the holding force.
H&S for magnets
Warning for heart patients
For implant holders: Powerful magnets affect medical devices. Maintain at least 30 cm distance or request help to work with the magnets.
Power loss in heat
Standard neodymium magnets (N-type) lose magnetization when the temperature exceeds 80°C. The loss of strength is permanent.
GPS Danger
Note: neodymium magnets generate a field that confuses sensitive sensors. Keep a separation from your phone, device, and navigation systems.
Safe distance
Equipment safety: Neodymium magnets can ruin payment cards and delicate electronics (pacemakers, medical aids, timepieces).
Sensitization to coating
It is widely known that nickel (the usual finish) is a strong allergen. If your skin reacts to metals, prevent direct skin contact and select encased magnets.
Conscious usage
Handle with care. Neodymium magnets act from a distance and snap with huge force, often quicker than you can move away.
Adults only
Strictly store magnets away from children. Ingestion danger is high, and the effects of magnets connecting inside the body are fatal.
Finger safety
Mind your fingers. Two powerful magnets will snap together instantly with a force of massive weight, crushing everything in their path. Be careful!
Machining danger
Powder generated during grinding of magnets is combustible. Do not drill into magnets unless you are an expert.
Beware of splinters
Neodymium magnets are sintered ceramics, meaning they are prone to chipping. Clashing of two magnets will cause them cracking into small pieces.
