Strengths and weaknesses of Nd2Fe14B magnets.
Benefits
- Their power is maintained, and after approximately ten years it decreases only by ~1% (theoretically),
- They show high resistance to demagnetization induced by external field influence,
- The use of an aesthetic coating of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Neodymium magnets deliver maximum magnetic induction on a small area, which ensures high operational effectiveness,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Possibility of custom creating and adjusting to concrete applications,
- Significant place in high-tech industry – they are utilized in data components, electric motors, diagnostic systems, and modern systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Disadvantages
- To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
- NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape as well as 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
- We suggest a housing - magnetic mount, due to difficulties in producing nuts inside the magnet and complex shapes.
- Potential hazard to health – tiny shards of magnets can be dangerous, in case of ingestion, which gains importance in the context of child health protection. Additionally, small components of these devices can disrupt the diagnostic process medical when they are in the body.
- With budget limitations the cost of neodymium magnets can be a barrier,
Pull force analysis
Maximum magnetic pulling force – what it depends on?
- on a plate made of structural steel, optimally conducting the magnetic flux
- possessing a massiveness of at least 10 mm to avoid saturation
- with a plane cleaned and smooth
- under conditions of gap-free contact (surface-to-surface)
- for force acting at a right angle (in the magnet axis)
- at ambient temperature room level
Determinants of practical lifting force of a magnet
- Distance – existence of any layer (paint, tape, gap) acts as an insulator, which reduces power steeply (even by 50% at 0.5 mm).
- Load vector – maximum parameter is available only during pulling at a 90° angle. The force required to slide of the magnet along the plate is typically many times lower (approx. 1/5 of the lifting capacity).
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Chemical composition of the base – mild steel gives the best results. Higher carbon content lower magnetic properties and lifting capacity.
- Smoothness – full contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
- Thermal environment – heating the magnet results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.
Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under parallel forces the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the holding force.
H&S for magnets
GPS Danger
A powerful magnetic field disrupts the functioning of magnetometers in smartphones and GPS navigation. Do not bring magnets close to a device to prevent breaking the sensors.
Conscious usage
Use magnets with awareness. Their immense force can surprise even professionals. Plan your moves and do not underestimate their power.
Mechanical processing
Powder produced during machining of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Pacemakers
Medical warning: Neodymium magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.
Demagnetization risk
Standard neodymium magnets (grade N) undergo demagnetization when the temperature exceeds 80°C. The loss of strength is permanent.
Fragile material
Despite metallic appearance, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.
No play value
Absolutely store magnets away from children. Choking hazard is significant, and the consequences of magnets connecting inside the body are tragic.
Avoid contact if allergic
It is widely known that the nickel plating (the usual finish) is a common allergen. If your skin reacts to metals, refrain from direct skin contact and opt for encased magnets.
Serious injuries
Protect your hands. Two powerful magnets will snap together immediately with a force of massive weight, destroying anything in their path. Be careful!
Protect data
Do not bring magnets near a purse, laptop, or screen. The magnetism can irreversibly ruin these devices and wipe information from cards.
