Advantages as well as disadvantages of rare earth magnets.
Pros
- They retain attractive force for almost 10 years – the drop is just ~1% (in theory),
- They are extremely resistant to demagnetization induced by external magnetic fields,
- Thanks to the elegant finish, the layer of Ni-Cu-Ni, gold, or silver-plated gives an professional appearance,
- They are known for high magnetic induction at the operating surface, making them more effective,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
- Thanks to the potential of accurate molding and adaptation to specialized needs, neodymium magnets can be created in a broad palette of shapes and sizes, which expands the range of possible applications,
- Universal use in high-tech industry – they serve a role in computer drives, motor assemblies, diagnostic systems, and industrial machines.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Weaknesses
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a special holder, which not only protects them against impacts but also raises their durability
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening 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 extremely resistant to heat
- They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Limited ability of producing nuts in the magnet and complex forms - recommended is cover - magnetic holder.
- Potential hazard to health – tiny shards of magnets pose a threat, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, small elements of these products can complicate diagnosis medical in case of swallowing.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- using a base made of low-carbon steel, acting as a magnetic yoke
- with a thickness minimum 10 mm
- with a surface perfectly flat
- without the slightest insulating layer between the magnet and steel
- under vertical force direction (90-degree angle)
- at conditions approx. 20°C
Magnet lifting force in use – key factors
- Space between surfaces – every millimeter of distance (caused e.g. by veneer or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Force direction – catalog parameter refers to pulling vertically. When attempting to slide, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of generating force.
- Plate material – low-carbon steel gives the best results. Alloy admixtures reduce magnetic properties and holding force.
- Surface finish – ideal contact is obtained only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
- Heat – NdFeB sinters have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate decreases the load capacity.
Precautions when working with NdFeB magnets
Bone fractures
Pinching hazard: The pulling power is so immense that it can cause blood blisters, pinching, and broken bones. Protective gloves are recommended.
Nickel coating and allergies
Medical facts indicate that nickel (standard magnet coating) is a common allergen. If your skin reacts to metals, refrain from touching magnets with bare hands or choose coated magnets.
Life threat
Health Alert: Strong magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.
Fire warning
Fire hazard: Rare earth powder is explosive. Avoid machining magnets without safety gear as this risks ignition.
Heat warning
Standard neodymium magnets (N-type) undergo demagnetization when the temperature goes above 80°C. Damage is permanent.
Shattering risk
Protect your eyes. Magnets can explode upon violent connection, launching sharp fragments into the air. We recommend safety glasses.
Do not underestimate power
Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.
Threat to navigation
Remember: rare earth magnets generate a field that confuses precision electronics. Maintain a safe distance from your mobile, device, and navigation systems.
Do not give to children
NdFeB magnets are not intended for children. Swallowing a few magnets may result in them connecting inside the digestive tract, which constitutes a direct threat to life and requires immediate surgery.
Safe distance
Avoid bringing magnets close to a purse, laptop, or TV. The magnetism can irreversibly ruin these devices and wipe information from cards.
