Pros as well as cons of Nd2Fe14B magnets.
Strengths
- They virtually do not lose strength, because even after ten years the performance loss is only ~1% (in laboratory conditions),
- Magnets very well protect themselves against loss of magnetization caused by external fields,
- Thanks to the reflective finish, the surface of nickel, gold-plated, or silver gives an visually attractive appearance,
- The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing feature,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Due to the option of flexible molding and adaptation to specialized needs, magnetic components can be manufactured in a variety of geometric configurations, which makes them more universal,
- Wide application in advanced technology sectors – they are utilized in mass storage devices, electromotive mechanisms, medical devices, also modern systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,
Limitations
- To avoid cracks under impact, we recommend using special steel holders. Such a solution protects the magnet and simultaneously increases its 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
- They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Due to limitations in producing nuts and complex forms in magnets, we recommend using casing - magnetic mount.
- Potential hazard resulting from small fragments of magnets are risky, in case of ingestion, which becomes key in the context of child safety. Furthermore, tiny parts 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 it depends on?
- with the application of a sheet made of special test steel, guaranteeing full magnetic saturation
- with a cross-section minimum 10 mm
- with an ideally smooth touching surface
- under conditions of ideal adhesion (metal-to-metal)
- under axial application of breakaway force (90-degree angle)
- at temperature approx. 20 degrees Celsius
Impact of factors on magnetic holding capacity in practice
- Gap between magnet and steel – every millimeter of distance (caused e.g. by veneer or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Force direction – remember that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
- Chemical composition of the base – mild steel attracts best. Alloy admixtures lower magnetic properties and holding force.
- Smoothness – full contact is possible only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
- Temperature – temperature increase causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.
Lifting capacity was assessed with the use of a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, however under shearing force the load capacity is reduced by as much as 5 times. Moreover, even a minimal clearance between the magnet and the plate lowers the load capacity.
Precautions when working with neodymium magnets
Choking Hazard
Product intended for adults. Tiny parts pose a choking risk, leading to serious injuries. Store away from children and animals.
Electronic devices
Avoid bringing magnets close to a purse, computer, or TV. The magnetism can irreversibly ruin these devices and wipe information from cards.
Finger safety
Big blocks can smash fingers instantly. Do not put your hand betwixt two strong magnets.
Do not underestimate power
Use magnets consciously. Their powerful strength can surprise even professionals. Stay alert and respect their force.
Permanent damage
Standard neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. The loss of strength is permanent.
Metal Allergy
Some people experience a hypersensitivity to Ni, which is the typical protective layer for NdFeB magnets. Extended handling may cause skin redness. It is best to wear protective gloves.
Magnetic interference
GPS units and mobile phones are highly susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can ruin the internal compass in your phone.
Flammability
Combustion risk: Rare earth powder is explosive. Do not process magnets in home conditions as this risks ignition.
Magnet fragility
Despite the nickel coating, the material is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Medical implants
Individuals with a ICD must keep an safe separation from magnets. The magnetic field can stop the functioning of the life-saving device.
