Pros and cons of neodymium magnets.
Pros
- They virtually do not lose power, because even after ten years the performance loss is only ~1% (in laboratory conditions),
- Magnets very well defend themselves against loss of magnetization caused by foreign field sources,
- By covering with a lustrous layer of silver, the element has an modern look,
- The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing feature,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Thanks to versatility in designing and the ability to modify to complex applications,
- Versatile presence in future technologies – they find application in magnetic memories, drive modules, medical equipment, and technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which enables their usage in compact constructions
Cons
- They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only shields the magnet but also improves its resistance to damage
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening 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 very resistant to heat
- They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- We suggest cover - magnetic mount, due to difficulties in creating threads inside the magnet and complex shapes.
- Health risk resulting from small fragments of magnets are risky, when accidentally swallowed, which becomes key in the context of child safety. Additionally, small components of these devices are able to be problematic in diagnostics medical in case of swallowing.
- Due to expensive raw materials, their price exceeds standard values,
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what affects it?
- on a plate made of structural steel, effectively closing the magnetic flux
- whose thickness equals approx. 10 mm
- with a surface cleaned and smooth
- under conditions of gap-free contact (metal-to-metal)
- for force acting at a right angle (pull-off, not shear)
- in temp. approx. 20°C
Determinants of lifting force in real conditions
- Air gap (between the magnet and the metal), because even a tiny clearance (e.g. 0.5 mm) results in a decrease in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
- Direction of force – highest force is obtained only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is usually several times lower (approx. 1/5 of the lifting capacity).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
- Material type – ideal substrate is high-permeability steel. Hardened steels may have worse magnetic properties.
- Smoothness – ideal contact is possible only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
- Thermal factor – hot environment reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity was measured using a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under attempts to slide the magnet the holding force is lower. Moreover, even a minimal clearance between the magnet and the plate reduces the lifting capacity.
Precautions when working with NdFeB magnets
Sensitization to coating
It is widely known that the nickel plating (the usual finish) is a potent allergen. If your skin reacts to metals, avoid touching magnets with bare hands or choose versions in plastic housing.
Crushing force
Big blocks can break fingers in a fraction of a second. Do not put your hand between two attracting surfaces.
Protect data
Device Safety: Neodymium magnets can damage payment cards and sensitive devices (pacemakers, medical aids, timepieces).
Adults only
Adult use only. Tiny parts pose a choking risk, leading to serious injuries. Keep out of reach of kids and pets.
Risk of cracking
NdFeB magnets are ceramic materials, meaning they are very brittle. Impact of two magnets leads to them cracking into small pieces.
Warning for heart patients
For implant holders: Powerful magnets disrupt electronics. Keep minimum 30 cm distance or ask another person to handle the magnets.
GPS Danger
Be aware: rare earth magnets produce a field that disrupts precision electronics. Keep a separation from your mobile, tablet, and GPS.
Do not underestimate power
Exercise caution. Neodymium magnets act from a long distance and connect with huge force, often faster than you can move away.
Operating temperature
Avoid heat. NdFeB magnets are susceptible to heat. If you require operation above 80°C, inquire about special high-temperature series (H, SH, UH).
Dust is flammable
Fire hazard: Neodymium dust is explosive. Avoid machining magnets in home conditions as this risks ignition.
