Pros as well as cons of Nd2Fe14B magnets.
Strengths
- They have stable power, and over more than ten years their attraction force decreases symbolically – ~1% (according to theory),
- They possess excellent resistance to magnetic field loss when exposed to opposing magnetic fields,
- In other words, due to the aesthetic finish of silver, the element gains visual value,
- The surface of neodymium magnets generates a strong magnetic field – this is a key feature,
- 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...
- Thanks to versatility in shaping and the capacity to adapt to unusual requirements,
- Versatile presence in advanced technology sectors – they serve a role in HDD drives, drive modules, medical devices, as well as modern systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,
Weaknesses
- To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Due to limitations in producing threads and complicated forms in magnets, we propose using casing - magnetic mount.
- Health risk to health – tiny shards of magnets pose a threat, in case of ingestion, which becomes key in the aspect of protecting the youngest. Furthermore, small components of these magnets are able to be problematic in diagnostics medical after entering the body.
- Due to complex production process, their price is relatively high,
Holding force characteristics
Maximum magnetic pulling force – what affects it?
- using a plate made of high-permeability steel, acting as a circuit closing element
- possessing a thickness of min. 10 mm to avoid saturation
- characterized by even structure
- with direct contact (without coatings)
- for force applied at a right angle (in the magnet axis)
- in neutral thermal conditions
Determinants of lifting force in real conditions
- Clearance – existence of any layer (rust, tape, gap) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
- Angle of force application – highest force is obtained only during pulling at a 90° angle. The shear force of the magnet along the plate is usually several times lower (approx. 1/5 of the lifting capacity).
- Base massiveness – insufficiently thick plate does not accept the full field, causing part of the flux to be lost into the air.
- Material composition – different alloys attracts identically. High carbon content weaken the interaction with the magnet.
- Surface finish – ideal contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
- Heat – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and in frost 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, whereas under parallel forces the holding force is lower. Moreover, even a small distance between the magnet and the plate decreases the load capacity.
H&S for magnets
Keep away from children
Adult use only. Small elements can be swallowed, leading to severe trauma. Store away from children and animals.
Keep away from electronics
GPS units and mobile phones are highly sensitive to magnetism. Direct contact with a strong magnet can permanently damage the sensors in your phone.
Keep away from computers
Do not bring magnets close to a purse, computer, or TV. The magnetism can permanently damage these devices and erase data from cards.
Allergic reactions
A percentage of the population have a sensitization to Ni, which is the common plating for NdFeB magnets. Prolonged contact may cause skin redness. We suggest use protective gloves.
Mechanical processing
Mechanical processing of neodymium magnets poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Respect the power
Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.
Heat warning
Avoid heat. NdFeB magnets are sensitive to heat. If you require operation above 80°C, inquire about HT versions (H, SH, UH).
Fragile material
Watch out for shards. Magnets can fracture upon uncontrolled impact, launching shards into the air. We recommend safety glasses.
ICD Warning
Health Alert: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have medical devices.
Finger safety
Big blocks can crush fingers instantly. Do not put your hand between two strong magnets.
