Pros as well as cons of Nd2Fe14B magnets.
Pros
- They do not lose strength, even during nearly 10 years – the reduction in power is only ~1% (based on measurements),
- They feature excellent resistance to magnetism drop when exposed to external fields,
- A magnet with a shiny gold surface has better aesthetics,
- Magnets exhibit very high magnetic induction on the working surface,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- In view of the possibility of free forming and adaptation to custom solutions, neodymium magnets can be produced in a broad palette of forms and dimensions, which makes them more universal,
- Huge importance in future technologies – they serve a role in hard drives, brushless drives, advanced medical instruments, and technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which enables their usage in miniature devices
Disadvantages
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also improves its resistance to damage
- Neodymium magnets decrease their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
- Limited ability of producing nuts in the magnet and complex shapes - recommended is casing - magnet mounting.
- Health risk to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, small elements of these magnets can disrupt the diagnostic process medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Magnetic strength at its maximum – what affects it?
- with the application of a sheet made of special test steel, guaranteeing full magnetic saturation
- whose thickness equals approx. 10 mm
- with a plane free of scratches
- under conditions of gap-free contact (metal-to-metal)
- for force applied at a right angle (in the magnet axis)
- at room temperature
Magnet lifting force in use – key factors
- Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
- Load vector – highest force is available only during perpendicular pulling. The shear force of the magnet along the plate is usually several times lower (approx. 1/5 of the lifting capacity).
- Steel thickness – insufficiently thick steel does not close the flux, causing part of the power to be wasted to the other side.
- Steel type – mild steel gives the best results. Alloy admixtures reduce magnetic permeability and lifting capacity.
- Base smoothness – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
- Thermal factor – hot environment reduces pulling force. Too high temperature can permanently demagnetize the magnet.
Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the load capacity is reduced by as much as fivefold. Additionally, even a minimal clearance between the magnet and the plate reduces the load capacity.
Safety rules for work with NdFeB magnets
Threat to navigation
Be aware: rare earth magnets produce a field that confuses sensitive sensors. Maintain a safe distance from your mobile, tablet, and navigation systems.
Bone fractures
Pinching hazard: The attraction force is so great that it can result in blood blisters, crushing, and even bone fractures. Use thick gloves.
Fire risk
Fire warning: Neodymium dust is highly flammable. Do not process magnets in home conditions as this may cause fire.
Beware of splinters
Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
Respect the power
Before starting, read the rules. Uncontrolled attraction can destroy the magnet or injure your hand. Be predictive.
Heat warning
Monitor thermal conditions. Heating the magnet to high heat will ruin its properties and strength.
Danger to pacemakers
Life threat: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.
Danger to the youngest
Absolutely store magnets away from children. Risk of swallowing is significant, and the consequences of magnets clamping inside the body are very dangerous.
Avoid contact if allergic
Certain individuals have a sensitization to nickel, which is the common plating for neodymium magnets. Extended handling may cause a rash. We strongly advise use safety gloves.
Electronic hazard
Device Safety: Strong magnets can damage data carriers and sensitive devices (heart implants, medical aids, mechanical watches).
