Strengths and weaknesses of rare earth magnets.
Advantages
- Their strength is maintained, and after around 10 years it decreases only by ~1% (theoretically),
- Neodymium magnets are characterized by extremely resistant to magnetic field loss caused by external field sources,
- In other words, due to the aesthetic layer of gold, the element is aesthetically pleasing,
- Neodymium magnets deliver maximum magnetic induction on a small surface, which increases force concentration,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Possibility of individual creating as well as optimizing to individual needs,
- Huge importance in innovative solutions – they are commonly used in hard drives, electric motors, precision medical tools, and technologically advanced constructions.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
- 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- We recommend cover - magnetic holder, due to difficulties in realizing threads inside the magnet and complicated shapes.
- Possible danger related to microscopic parts of magnets are risky, if swallowed, which gains importance in the context of child health protection. Additionally, small elements of these products can be problematic in diagnostics medical in case of swallowing.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities
Lifting parameters
Highest magnetic holding force – what contributes to it?
- using a sheet made of low-carbon steel, serving as a circuit closing element
- whose thickness reaches at least 10 mm
- characterized by lack of roughness
- under conditions of ideal adhesion (metal-to-metal)
- for force acting at a right angle (pull-off, not shear)
- at ambient temperature room level
What influences lifting capacity in practice
- Distance – the presence of foreign body (rust, tape, gap) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
- Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Base massiveness – insufficiently thick steel does not accept the full field, causing part of the power to be escaped into the air.
- Plate material – mild steel gives the best results. Alloy steels decrease magnetic permeability and holding force.
- Surface finish – full contact is possible only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
- Thermal conditions – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).
Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under shearing force the holding force is lower. In addition, even a slight gap between the magnet and the plate lowers the lifting capacity.
Precautions when working with NdFeB magnets
Fire warning
Combustion risk: Neodymium dust is highly flammable. Do not process magnets without safety gear as this risks ignition.
Allergy Warning
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If an allergic reaction appears, cease handling magnets and use protective gear.
Safe distance
Data protection: Neodymium magnets can ruin data carriers and delicate electronics (heart implants, hearing aids, mechanical watches).
Safe operation
Use magnets consciously. Their immense force can shock even professionals. Stay alert and do not underestimate their power.
This is not a toy
Absolutely store magnets away from children. Ingestion danger is high, and the effects of magnets connecting inside the body are tragic.
Operating temperature
Regular neodymium magnets (grade N) undergo demagnetization when the temperature goes above 80°C. Damage is permanent.
Beware of splinters
Despite metallic appearance, the material is brittle and not impact-resistant. Do not hit, as the magnet may shatter into hazardous fragments.
Serious injuries
Risk of injury: The pulling power is so great that it can result in hematomas, pinching, and even bone fractures. Use thick gloves.
GPS and phone interference
GPS units and smartphones are highly susceptible to magnetism. Direct contact with a powerful NdFeB magnet can permanently damage the internal compass in your phone.
Warning for heart patients
Warning for patients: Strong magnetic fields affect medical devices. Keep at least 30 cm distance or ask another person to handle the magnets.
