Advantages as well as disadvantages of Nd2Fe14B magnets.
Advantages
- They have stable power, and over around ten years their performance decreases symbolically – ~1% (in testing),
- Magnets perfectly protect themselves against loss of magnetization caused by external fields,
- A magnet with a shiny gold surface has an effective appearance,
- Magnets have very high magnetic induction on the outer side,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to versatility in forming and the ability to customize to individual projects,
- Universal use in innovative solutions – they are utilized in magnetic memories, electromotive mechanisms, diagnostic systems, as well as modern systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- At strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- NdFeB magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop 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 very resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- Due to limitations in realizing threads and complex shapes in magnets, we recommend using a housing - magnetic mount.
- Health risk resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child health protection. It is also worth noting that small components of these magnets are able to be problematic in diagnostics medical when they are in the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities
Holding force characteristics
Highest magnetic holding force – what affects it?
- on a plate made of structural steel, optimally conducting the magnetic flux
- possessing a massiveness of min. 10 mm to avoid saturation
- characterized by lack of roughness
- under conditions of ideal adhesion (metal-to-metal)
- under vertical force direction (90-degree angle)
- at standard ambient temperature
Lifting capacity in practice – influencing factors
- Air gap (between the magnet and the plate), as even a microscopic clearance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to paint, corrosion or dirt).
- Loading method – catalog parameter refers to pulling vertically. When applying parallel force, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
- Element thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Steel type – mild steel attracts best. Alloy admixtures lower magnetic properties and lifting capacity.
- Surface quality – the smoother and more polished the surface, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
- Temperature influence – hot environment reduces pulling force. Too high temperature can permanently demagnetize the magnet.
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under shearing force the holding force is lower. In addition, even a small distance between the magnet’s surface and the plate lowers the load capacity.
Precautions when working with neodymium magnets
Warning for heart patients
Warning for patients: Powerful magnets disrupt medical devices. Maintain at least 30 cm distance or ask another person to handle the magnets.
Heat sensitivity
Standard neodymium magnets (grade N) lose power when the temperature goes above 80°C. This process is irreversible.
Protect data
Avoid bringing magnets near a wallet, laptop, or TV. The magnetism can permanently damage these devices and wipe information from cards.
Keep away from children
Absolutely keep magnets out of reach of children. Ingestion danger is high, and the consequences of magnets clamping inside the body are fatal.
Beware of splinters
Despite metallic appearance, neodymium is delicate and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
Magnetic interference
Note: rare earth magnets produce a field that disrupts precision electronics. Maintain a safe distance from your phone, tablet, and GPS.
Sensitization to coating
Medical facts indicate that nickel (the usual finish) is a strong allergen. If your skin reacts to metals, prevent touching magnets with bare hands and opt for coated magnets.
Dust explosion hazard
Fire warning: Rare earth powder is explosive. Avoid machining magnets in home conditions as this may cause fire.
Handling rules
Handle magnets with awareness. Their powerful strength can shock even professionals. Stay alert and do not underestimate their force.
Bodily injuries
Risk of injury: The pulling power is so immense that it can cause blood blisters, pinching, and broken bones. Use thick gloves.
