Advantages and disadvantages of neodymium magnets.
Pros
- Their strength is durable, and after around ten years it decreases only by ~1% (according to research),
- Neodymium magnets are characterized by remarkably resistant to loss of magnetic properties caused by external magnetic fields,
- The use of an refined finish of noble metals (nickel, gold, silver) causes the element to look better,
- Magnets have exceptionally strong magnetic induction on the surface,
- 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 ability of precise shaping and customization to custom needs, neodymium magnets can be modeled in a broad palette of geometric configurations, which amplifies use scope,
- Fundamental importance in modern technologies – they are used in HDD drives, brushless drives, diagnostic systems, also other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which enables their usage in compact constructions
Cons
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a steel housing, which not only protects them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
- Limited possibility of making nuts in the magnet and complex forms - preferred is cover - mounting mechanism.
- Possible danger resulting from small fragments of magnets are risky, when accidentally swallowed, which gains importance in the context of child safety. Furthermore, small elements of these devices can complicate diagnosis medical in case of swallowing.
- With large orders the cost of neodymium magnets is economically unviable,
Lifting parameters
Magnetic strength at its maximum – what affects it?
- using a plate made of mild steel, serving as a circuit closing element
- whose transverse dimension is min. 10 mm
- with a surface cleaned and smooth
- without any air gap between the magnet and steel
- under perpendicular application of breakaway force (90-degree angle)
- in neutral thermal conditions
Practical aspects of lifting capacity – factors
- Gap (betwixt the magnet and the plate), since even a very small clearance (e.g. 0.5 mm) leads to a decrease in lifting capacity by up to 50% (this also applies to paint, rust or dirt).
- Force direction – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet exhibits much less (typically approx. 20-30% of nominal force).
- Plate thickness – too thin sheet does not accept the full field, causing part of the flux to be escaped to the other side.
- Steel type – low-carbon steel attracts best. Alloy steels lower magnetic properties and lifting capacity.
- Surface quality – the more even the surface, the better the adhesion and stronger the hold. Roughness creates an air distance.
- Heat – NdFeB sinters have a negative temperature coefficient. At higher temperatures they lose power, and in frost gain strength (up to a certain limit).
Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under perpendicular forces, in contrast under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Moreover, even a small distance between the magnet’s surface and the plate reduces the holding force.
Safe handling of neodymium magnets
Maximum temperature
Avoid heat. NdFeB magnets are susceptible to temperature. If you require resistance above 80°C, ask us about HT versions (H, SH, UH).
Combustion hazard
Fire hazard: Rare earth powder is explosive. Avoid machining magnets without safety gear as this risks ignition.
Immense force
Before use, check safety instructions. Sudden snapping can break the magnet or hurt your hand. Think ahead.
GPS and phone interference
Be aware: rare earth magnets produce a field that disrupts precision electronics. Maintain a safe distance from your phone, tablet, and navigation systems.
Risk of cracking
Despite metallic appearance, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Medical interference
Life threat: Neodymium magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.
No play value
These products are not intended for children. Eating multiple magnets can lead to them pinching intestinal walls, which constitutes a severe health hazard and requires urgent medical intervention.
Sensitization to coating
Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If skin irritation occurs, cease handling magnets and wear gloves.
Crushing force
Danger of trauma: The attraction force is so immense that it can result in blood blisters, pinching, and even bone fractures. Use thick gloves.
Keep away from computers
Device Safety: Neodymium magnets can damage data carriers and delicate electronics (heart implants, hearing aids, mechanical watches).
