Advantages as well as disadvantages of Nd2Fe14B magnets.
Strengths
- They virtually do not lose power, because even after ten years the performance loss is only ~1% (according to literature),
- They have excellent resistance to weakening of magnetic properties when exposed to opposing magnetic fields,
- In other words, due to the reflective finish of gold, the element looks attractive,
- Magnets have impressive magnetic induction on the outer side,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Possibility of detailed creating and optimizing to complex requirements,
- Versatile presence in electronics industry – they find application in computer drives, drive modules, advanced medical instruments, as well as complex engineering applications.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Cons
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a strong case, which not only protects them against impacts but also raises their durability
- Neodymium magnets lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- We recommend a housing - magnetic mount, due to difficulties in producing nuts inside the magnet and complicated forms.
- Potential hazard resulting from small fragments of magnets are risky, if swallowed, which becomes key in the context of child health protection. Furthermore, small components of these magnets are able to be problematic in diagnostics medical when they are in the body.
- Due to expensive raw materials, their price is relatively high,
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what it depends on?
- using a base made of high-permeability steel, functioning as a ideal flux conductor
- possessing a thickness of min. 10 mm to avoid saturation
- characterized by even structure
- with direct contact (no paint)
- for force acting at a right angle (pull-off, not shear)
- in stable room temperature
Determinants of practical lifting force of a magnet
- Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by veneer or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
- Direction of force – highest force is reached only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is typically several times smaller (approx. 1/5 of the lifting capacity).
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Material composition – different alloys reacts the same. Alloy additives weaken the attraction effect.
- Smoothness – ideal contact is obtained only on smooth steel. Rough texture create air cushions, weakening the magnet.
- Thermal factor – hot environment reduces pulling force. Too high temperature can permanently damage the magnet.
Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, however under attempts to slide the magnet the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate lowers the lifting capacity.
Precautions when working with NdFeB magnets
Adults only
Strictly store magnets out of reach of children. Choking hazard is significant, and the consequences of magnets clamping inside the body are very dangerous.
Pacemakers
Individuals with a ICD should maintain an large gap from magnets. The magnetic field can interfere with the functioning of the life-saving device.
Warning for allergy sufferers
Some people have a sensitization to nickel, which is the typical protective layer for NdFeB magnets. Frequent touching can result in skin redness. We recommend use protective gloves.
Caution required
Exercise caution. Rare earth magnets act from a long distance and snap with massive power, often quicker than you can move away.
Phone sensors
Remember: rare earth magnets produce a field that interferes with sensitive sensors. Maintain a separation from your mobile, tablet, and navigation systems.
Pinching danger
Big blocks can crush fingers in a fraction of a second. Never put your hand between two attracting surfaces.
Magnet fragility
Despite metallic appearance, neodymium is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.
Maximum temperature
Regular neodymium magnets (grade N) undergo demagnetization when the temperature surpasses 80°C. The loss of strength is permanent.
Fire warning
Powder produced during cutting of magnets is combustible. Avoid drilling into magnets unless you are an expert.
Electronic devices
Data protection: Strong magnets can damage data carriers and sensitive devices (heart implants, hearing aids, timepieces).
