Advantages as well as disadvantages of rare earth magnets.
Pros
- They retain full power for around 10 years – the drop is just ~1% (according to analyses),
- Neodymium magnets are characterized by remarkably resistant to magnetic field loss caused by external field sources,
- In other words, due to the smooth surface of nickel, the element becomes visually attractive,
- The surface of neodymium magnets generates a unique magnetic field – this is one of their assets,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling action at temperatures reaching 230°C and above...
- Possibility of individual shaping as well as optimizing to atypical conditions,
- Fundamental importance in advanced technology sectors – they are utilized in HDD drives, electric drive systems, medical equipment, as well as other advanced devices.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also improves its resistance to damage
- Neodymium magnets decrease their power 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 durability even at temperatures 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 those in rubber or plastics, which secure oxidation and corrosion.
- Due to limitations in realizing threads and complex shapes in magnets, we recommend using cover - magnetic mechanism.
- Potential hazard to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which is particularly important in the context of child health protection. Furthermore, tiny parts of these products are able to be problematic in diagnostics medical after entering the body.
- Due to expensive raw materials, their price is relatively high,
Pull force analysis
Highest magnetic holding force – what affects it?
- with the application of a yoke made of low-carbon steel, guaranteeing maximum field concentration
- whose thickness equals approx. 10 mm
- with a plane cleaned and smooth
- without any insulating layer between the magnet and steel
- under axial force vector (90-degree angle)
- in temp. approx. 20°C
Impact of factors on magnetic holding capacity in practice
- Air gap (betwixt the magnet and the metal), since even a microscopic clearance (e.g. 0.5 mm) can cause a reduction in force by up to 50% (this also applies to varnish, rust or debris).
- Load vector – highest force is available only during pulling at a 90° angle. The force required to slide of the magnet along the plate is usually many times smaller (approx. 1/5 of the lifting capacity).
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Metal type – not every steel attracts identically. Alloy additives worsen the interaction with the magnet.
- Base smoothness – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
- Thermal environment – heating the magnet results in weakening of force. Check the maximum operating temperature for a given model.
Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under shearing force the holding force is lower. Moreover, even a small distance between the magnet and the plate lowers the load capacity.
H&S for magnets
Operating temperature
Control the heat. Exposing the magnet above 80 degrees Celsius will destroy its properties and pulling force.
Physical harm
Pinching hazard: The pulling power is so great that it can result in hematomas, crushing, and even bone fractures. Protective gloves are recommended.
Product not for children
Neodymium magnets are not suitable for play. Accidental ingestion of a few magnets may result in them attracting across intestines, which poses a direct threat to life and necessitates immediate surgery.
GPS Danger
Note: neodymium magnets produce a field that disrupts precision electronics. Keep a safe distance from your phone, device, and GPS.
Magnet fragility
Despite metallic appearance, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.
Medical interference
Patients with a pacemaker have to keep an absolute distance from magnets. The magnetism can stop the functioning of the implant.
Metal Allergy
Medical facts indicate that nickel (the usual finish) is a common allergen. If your skin reacts to metals, avoid direct skin contact and opt for coated magnets.
Caution required
Before starting, read the rules. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.
Threat to electronics
Device Safety: Strong magnets can ruin data carriers and sensitive devices (pacemakers, medical aids, timepieces).
Flammability
Fire hazard: Neodymium dust is highly flammable. Avoid machining magnets in home conditions as this risks ignition.
