Strengths as well as weaknesses of rare earth magnets.
Benefits
- They retain attractive force for around ten years – the drop is just ~1% (in theory),
- They show high resistance to demagnetization induced by presence of other magnetic fields,
- A magnet with a shiny silver surface has an effective appearance,
- They feature high magnetic induction at the operating surface, which affects their effectiveness,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Due to the ability of precise molding and customization to custom projects, neodymium magnets can be produced in a variety of forms and dimensions, which expands the range of possible applications,
- Significant place in high-tech industry – they serve a role in computer drives, electric drive systems, medical devices, and other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which allows their use in miniature devices
Weaknesses
- To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- We suggest a housing - magnetic mount, due to difficulties in realizing threads inside the magnet and complicated forms.
- Potential hazard related to microscopic parts of magnets can be dangerous, in case of ingestion, which gains importance in the context of child safety. It is also worth noting that tiny parts of these products are able to complicate diagnosis 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
Pull force analysis
Maximum lifting capacity of the magnet – what affects it?
- on a block made of structural steel, effectively closing the magnetic field
- whose thickness is min. 10 mm
- with an ground touching surface
- without the slightest insulating layer between the magnet and steel
- under axial force direction (90-degree angle)
- in neutral thermal conditions
Magnet lifting force in use – key factors
- Air gap (betwixt the magnet and the metal), because even a microscopic distance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to paint, rust or debris).
- Force direction – catalog parameter refers to pulling vertically. When slipping, the magnet holds much less (often approx. 20-30% of maximum force).
- Base massiveness – too thin sheet causes magnetic saturation, causing part of the flux to be wasted into the air.
- Steel type – mild steel gives the best results. Alloy steels lower magnetic permeability and lifting capacity.
- Surface finish – full contact is possible only on polished steel. Rough texture reduce the real contact area, reducing force.
- Temperature – heating the magnet causes a temporary drop of induction. Check the thermal limit for a given model.
Lifting capacity was measured using a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular detachment force, in contrast under shearing force the holding force is lower. Additionally, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.
Safety rules for work with NdFeB magnets
GPS and phone interference
Navigation devices and smartphones are extremely susceptible to magnetism. Direct contact with a strong magnet can permanently damage the internal compass in your phone.
Protect data
Do not bring magnets near a wallet, computer, or screen. The magnetism can destroy these devices and erase data from cards.
Nickel coating and allergies
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If an allergic reaction appears, immediately stop working with magnets and wear gloves.
Hand protection
Big blocks can crush fingers in a fraction of a second. Under no circumstances place your hand betwixt two attracting surfaces.
Demagnetization risk
Regular neodymium magnets (grade N) lose power when the temperature exceeds 80°C. Damage is permanent.
Dust is flammable
Powder produced during grinding of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
Medical interference
Individuals with a heart stimulator have to maintain an large gap from magnets. The magnetic field can disrupt the operation of the implant.
Choking Hazard
NdFeB magnets are not suitable for play. Accidental ingestion of multiple magnets can lead to them connecting inside the digestive tract, which poses a severe health hazard and necessitates urgent medical intervention.
Immense force
Use magnets consciously. Their huge power can surprise even experienced users. Plan your moves and respect their power.
Eye protection
NdFeB magnets are sintered ceramics, meaning they are fragile like glass. Collision of two magnets leads to them cracking into shards.
