Strengths and weaknesses of Nd2Fe14B magnets.
Benefits
- Their magnetic field remains stable, and after approximately 10 years it decreases only by ~1% (according to research),
- Neodymium magnets are remarkably resistant to demagnetization caused by external magnetic fields,
- Thanks to the reflective finish, the plating of nickel, gold-plated, or silver gives an modern appearance,
- Magnetic induction on the working layer of the magnet is strong,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to the ability of precise shaping and customization to individualized solutions, neodymium magnets can be produced in a variety of geometric configurations, which makes them more universal,
- Significant place in modern technologies – they serve a role in HDD drives, brushless drives, advanced medical instruments, as well as complex engineering applications.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Weaknesses
- At strong impacts they can break, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- 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
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
- We suggest a housing - magnetic holder, due to difficulties in producing nuts inside the magnet and complicated shapes.
- Health risk resulting from small fragments of magnets can be dangerous, in case of ingestion, which gains importance in the context of child safety. Furthermore, tiny parts of these products are able to be problematic in diagnostics medical after entering the body.
- Due to neodymium price, their price is relatively high,
Holding force characteristics
Maximum holding power of the magnet – what it depends on?
- on a plate made of structural steel, effectively closing the magnetic field
- possessing a massiveness of min. 10 mm to avoid saturation
- characterized by lack of roughness
- without any insulating layer between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- at ambient temperature approx. 20 degrees Celsius
Determinants of practical lifting force of a magnet
- Gap (between the magnet and the plate), as even a tiny distance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
- Force direction – catalog parameter refers to detachment vertically. When slipping, the magnet exhibits much less (often approx. 20-30% of nominal force).
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
- Plate material – mild steel gives the best results. Alloy admixtures reduce magnetic properties and holding force.
- Smoothness – ideal contact is possible only on smooth steel. Rough texture reduce the real contact area, reducing force.
- Heat – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and at low temperatures gain strength (up to a certain limit).
Lifting capacity testing was performed on a smooth plate of optimal thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the load capacity is reduced by as much as fivefold. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.
H&S for magnets
Maximum temperature
Control the heat. Exposing the magnet above 80 degrees Celsius will destroy its magnetic structure and strength.
Keep away from electronics
GPS units and mobile phones are extremely susceptible to magnetism. Close proximity with a powerful NdFeB magnet can ruin the internal compass in your phone.
Handling rules
Handle with care. Rare earth magnets attract from a long distance and snap with huge force, often quicker than you can move away.
Electronic devices
Avoid bringing magnets close to a wallet, computer, or TV. The magnetism can destroy these devices and wipe information from cards.
Health Danger
Warning for patients: Powerful magnets disrupt medical devices. Keep minimum 30 cm distance or request help to work with the magnets.
Do not drill into magnets
Powder produced during grinding of magnets is self-igniting. Do not drill into magnets unless you are an expert.
Physical harm
Large magnets can crush fingers in a fraction of a second. Do not place your hand between two strong magnets.
Magnet fragility
Protect your eyes. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. We recommend safety glasses.
Product not for children
Always store magnets out of reach of children. Choking hazard is high, and the consequences of magnets clamping inside the body are tragic.
Skin irritation risks
Nickel alert: The nickel-copper-nickel coating contains nickel. If an allergic reaction appears, cease handling magnets and use protective gear.
