Advantages and disadvantages of rare earth magnets.
Advantages
- Their power remains stable, and after around ten years it decreases only by ~1% (theoretically),
- They possess excellent resistance to magnetic field loss due to external fields,
- Thanks to the glossy finish, the plating of Ni-Cu-Ni, gold-plated, or silver gives an visually attractive appearance,
- They feature high magnetic induction at the operating surface, making them more effective,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- In view of the ability of accurate molding and adaptation to custom solutions, magnetic components can be produced in a variety of shapes and sizes, which makes them more universal,
- Huge importance in innovative solutions – they are utilized in mass storage devices, motor assemblies, medical equipment, and other advanced devices.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Cons
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a strong case, which not only secures them against impacts but also increases 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 those in rubber or plastics, which prevent oxidation as well as corrosion.
- Due to limitations in realizing threads and complicated forms in magnets, we propose using casing - magnetic holder.
- Health risk to health – tiny shards of magnets pose a threat, when accidentally swallowed, which becomes key in the context of child safety. Additionally, small components of these magnets can disrupt the diagnostic process medical in case of swallowing.
- With budget limitations the cost of neodymium magnets can be a barrier,
Pull force analysis
Magnetic strength at its maximum – what affects it?
- using a plate made of mild steel, acting as a ideal flux conductor
- possessing a thickness of at least 10 mm to avoid saturation
- characterized by lack of roughness
- without any air gap between the magnet and steel
- during pulling in a direction perpendicular to the plane
- at conditions approx. 20°C
Practical lifting capacity: influencing factors
- Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by varnish or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
- Metal type – not every steel attracts identically. Alloy additives weaken the attraction effect.
- Surface quality – the more even the plate, the larger the contact zone and stronger the hold. Roughness creates an air distance.
- Temperature – heating the magnet causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.
Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under parallel forces the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate lowers the holding force.
Safe handling of NdFeB magnets
Do not underestimate power
Handle with care. Rare earth magnets attract from a distance and snap with massive power, often faster than you can move away.
Protective goggles
Despite metallic appearance, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.
Data carriers
Powerful magnetic fields can destroy records on credit cards, hard drives, and storage devices. Maintain a gap of at least 10 cm.
Nickel coating and allergies
Medical facts indicate that nickel (the usual finish) is a potent allergen. For allergy sufferers, avoid touching magnets with bare hands or choose encased magnets.
This is not a toy
Strictly keep magnets away from children. Risk of swallowing is significant, and the consequences of magnets connecting inside the body are tragic.
Medical implants
For implant holders: Strong magnetic fields disrupt medical devices. Keep minimum 30 cm distance or request help to handle the magnets.
Pinching danger
Large magnets can break fingers instantly. Do not place your hand between two attracting surfaces.
Precision electronics
Remember: neodymium magnets produce a field that confuses precision electronics. Maintain a safe distance from your mobile, device, and navigation systems.
Mechanical processing
Dust created during grinding of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
Operating temperature
Control the heat. Exposing the magnet above 80 degrees Celsius will ruin its properties and strength.
