Pros as well as cons of Nd2Fe14B magnets.
Strengths
- They do not lose magnetism, even after around ten years – the reduction in power is only ~1% (based on measurements),
- They retain their magnetic properties even under close interference source,
- By using a reflective coating of gold, the element presents an professional look,
- They show high magnetic induction at the operating surface, making them more effective,
- Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
- Due to the option of precise shaping and adaptation to individualized projects, magnetic components can be created in a variety of shapes and sizes, which makes them more universal,
- Significant place in electronics industry – they are commonly used in computer drives, drive modules, diagnostic systems, also technologically advanced constructions.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a steel housing, which not only protects them against impacts but also raises their durability
- NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (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 extremely resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- Limited possibility of producing nuts in the magnet and complex forms - preferred is cover - magnetic holder.
- Potential hazard related to microscopic parts of magnets pose a threat, in case of ingestion, which gains importance in the aspect of protecting the youngest. Furthermore, tiny parts of these products can disrupt the diagnostic process medical in case of swallowing.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities
Pull force analysis
Best holding force of the magnet in ideal parameters – what affects it?
- on a block made of mild steel, perfectly concentrating the magnetic flux
- possessing a thickness of at least 10 mm to avoid saturation
- characterized by even structure
- under conditions of ideal adhesion (surface-to-surface)
- under axial force direction (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Determinants of lifting force in real conditions
- Gap between magnet and steel – every millimeter of separation (caused e.g. by veneer or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Loading method – catalog parameter refers to detachment vertically. When slipping, the magnet holds much less (typically approx. 20-30% of maximum force).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
- Plate material – low-carbon steel attracts best. Alloy steels lower magnetic properties and holding force.
- Surface condition – smooth surfaces ensure maximum contact, which increases field saturation. Uneven metal reduce efficiency.
- Temperature influence – hot environment weakens pulling force. Too high temperature can permanently demagnetize the magnet.
Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under parallel forces the load capacity is reduced by as much as 5 times. Moreover, even a minimal clearance between the magnet and the plate reduces the lifting capacity.
Warnings
Health Danger
For implant holders: Powerful magnets disrupt medical devices. Keep minimum 30 cm distance or ask another person to handle the magnets.
Keep away from computers
Do not bring magnets close to a wallet, computer, or screen. The magnetic field can permanently damage these devices and wipe information from cards.
Compass and GPS
Be aware: rare earth magnets produce a field that disrupts precision electronics. Maintain a safe distance from your phone, tablet, and navigation systems.
Bodily injuries
Watch your fingers. Two powerful magnets will join instantly with a force of massive weight, destroying anything in their path. Be careful!
Do not underestimate power
Be careful. Rare earth magnets attract from a distance and snap with huge force, often quicker than you can move away.
Adults only
Absolutely store magnets out of reach of children. Choking hazard is significant, and the effects of magnets clamping inside the body are very dangerous.
Combustion hazard
Machining of NdFeB material poses a fire hazard. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Demagnetization risk
Do not overheat. NdFeB magnets are sensitive to temperature. If you need resistance above 80°C, look for special high-temperature series (H, SH, UH).
Sensitization to coating
Certain individuals have a sensitization to nickel, which is the common plating for neodymium magnets. Extended handling might lead to dermatitis. It is best to use protective gloves.
Eye protection
Despite metallic appearance, the material is delicate and cannot withstand shocks. Do not hit, as the magnet may shatter into hazardous fragments.
