Pros and cons of neodymium magnets.
Benefits
- They do not lose magnetism, even during approximately ten years – the decrease in lifting capacity is only ~1% (theoretically),
- They have excellent resistance to magnetic field loss as a result of opposing magnetic fields,
- In other words, due to the glossy layer of silver, the element becomes visually attractive,
- Magnetic induction on the working part of the magnet turns out to be exceptional,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- Thanks to freedom in designing and the capacity to modify to complex applications,
- Universal use in advanced technology sectors – they are utilized in data components, electric drive systems, advanced medical instruments, as well as technologically advanced constructions.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Cons
- To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
- Neodymium magnets decrease 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 stability 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 as well as corrosion.
- We recommend cover - magnetic mount, due to difficulties in producing threads inside the magnet and complex shapes.
- Potential hazard related to microscopic parts of magnets are risky, if swallowed, which is particularly important in the context of child safety. It is also worth noting that small elements of these magnets can complicate diagnosis medical when they are in the body.
- With mass production the cost of neodymium magnets is a challenge,
Lifting parameters
Maximum holding power of the magnet – what affects it?
- on a base made of structural steel, optimally conducting the magnetic field
- with a cross-section no less than 10 mm
- characterized by lack of roughness
- without the slightest air gap between the magnet and steel
- for force applied at a right angle (in the magnet axis)
- in stable room temperature
Practical lifting capacity: influencing factors
- Space between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Loading method – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet exhibits significantly lower power (typically approx. 20-30% of nominal force).
- Plate thickness – too thin sheet does not close the flux, causing part of the flux to be wasted into the air.
- Material type – ideal substrate is pure iron steel. Stainless steels may attract less.
- Surface quality – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
- Operating temperature – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and at low temperatures gain strength (up to a certain limit).
Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under shearing force the holding force is lower. Additionally, even a minimal clearance between the magnet and the plate reduces the holding force.
H&S for magnets
Magnetic media
Do not bring magnets near a wallet, laptop, or TV. The magnetic field can destroy these devices and wipe information from cards.
Avoid contact if allergic
Nickel alert: The nickel-copper-nickel coating consists of nickel. If an allergic reaction occurs, cease working with magnets and use protective gear.
Risk of cracking
Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
Physical harm
Big blocks can crush fingers in a fraction of a second. Never put your hand between two strong magnets.
Precision electronics
Note: rare earth magnets produce a field that confuses sensitive sensors. Maintain a safe distance from your phone, tablet, and navigation systems.
Safe operation
Be careful. Neodymium magnets attract from a distance and connect with massive power, often faster than you can move away.
Swallowing risk
Neodymium magnets are not suitable for play. Swallowing multiple magnets can lead to them attracting across intestines, which poses a critical condition and requires urgent medical intervention.
Life threat
For implant holders: Strong magnetic fields affect electronics. Keep minimum 30 cm distance or ask another person to work with the magnets.
Do not drill into magnets
Fire hazard: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this may cause fire.
Operating temperature
Standard neodymium magnets (grade N) undergo demagnetization when the temperature exceeds 80°C. The loss of strength is permanent.
