Advantages and disadvantages of neodymium magnets.
Strengths
- Their strength is maintained, and after approximately 10 years it drops only by ~1% (theoretically),
- They are noted for resistance to demagnetization induced by external field influence,
- The use of an shiny layer of noble metals (nickel, gold, silver) causes the element to present itself better,
- Magnets have maximum magnetic induction on the active area,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling action at temperatures reaching 230°C and above...
- Possibility of custom forming and adjusting to atypical requirements,
- Universal use in future technologies – they are used in hard drives, electromotive mechanisms, diagnostic systems, and industrial machines.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Weaknesses
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also increases 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 stability even at temperatures up to 230°C
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
- Limited possibility of making threads in the magnet and complex forms - preferred is casing - mounting mechanism.
- Possible danger to health – tiny shards of magnets are risky, if swallowed, which becomes key in the context of child safety. Furthermore, tiny parts of these products are able to disrupt the diagnostic process medical in case of swallowing.
- With budget limitations the cost of neodymium magnets is economically unviable,
Pull force analysis
Highest magnetic holding force – what contributes to it?
- on a block made of mild steel, perfectly concentrating the magnetic flux
- possessing a massiveness of min. 10 mm to ensure full flux closure
- with a surface free of scratches
- with zero gap (no coatings)
- under vertical force vector (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Determinants of practical lifting force of a magnet
- Gap (betwixt the magnet and the plate), as even a very small distance (e.g. 0.5 mm) can cause a decrease in force by up to 50% (this also applies to paint, corrosion or dirt).
- Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of generating force.
- Material type – ideal substrate is high-permeability steel. Hardened steels may generate lower lifting capacity.
- Surface quality – the smoother and more polished the plate, the better the adhesion and stronger the hold. Roughness acts like micro-gaps.
- Operating temperature – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the load capacity is reduced by as much as 5 times. In addition, even a slight gap between the magnet’s surface and the plate lowers the holding force.
Safe handling of neodymium magnets
Nickel allergy
Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If an allergic reaction appears, cease handling magnets and use protective gear.
Crushing risk
Risk of injury: The attraction force is so great that it can result in blood blisters, pinching, and broken bones. Use thick gloves.
Magnetic media
Avoid bringing magnets close to a wallet, computer, or screen. The magnetism can permanently damage these devices and wipe information from cards.
Product not for children
Always store magnets out of reach of children. Ingestion danger is high, and the consequences of magnets connecting inside the body are life-threatening.
Safe operation
Handle with care. Neodymium magnets attract from a long distance and connect with massive power, often faster than you can react.
Magnets are brittle
NdFeB magnets are ceramic materials, which means they are very brittle. Collision of two magnets leads to them breaking into shards.
GPS Danger
GPS units and mobile phones are extremely sensitive to magnetism. Direct contact with a strong magnet can ruin the internal compass in your phone.
Life threat
Health Alert: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.
Machining danger
Powder produced during cutting of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
Demagnetization risk
Do not overheat. Neodymium magnets are sensitive to temperature. If you need resistance above 80°C, look for HT versions (H, SH, UH).
