Pros and cons of rare earth magnets.
Benefits
- They retain magnetic properties for almost 10 years – the drop is just ~1% (based on simulations),
- They are extremely resistant to demagnetization induced by external magnetic fields,
- In other words, due to the metallic surface of nickel, the element becomes visually attractive,
- The surface of neodymium magnets generates a concentrated magnetic field – this is a distinguishing feature,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Possibility of detailed shaping as well as adapting to specific requirements,
- Fundamental importance in electronics industry – they are commonly used in HDD drives, brushless drives, advanced medical instruments, also technologically advanced constructions.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Weaknesses
- At strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets lose 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 usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
- We suggest casing - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complicated forms.
- Health risk to health – tiny shards of magnets can be dangerous, in case of ingestion, which gains importance in the context of child safety. It is also worth noting that small components of these magnets can complicate diagnosis medical in case of swallowing.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities
Lifting parameters
Magnetic strength at its maximum – what contributes to it?
- on a block made of structural steel, optimally conducting the magnetic flux
- whose transverse dimension is min. 10 mm
- characterized by lack of roughness
- with total lack of distance (no impurities)
- under perpendicular force direction (90-degree angle)
- in temp. approx. 20°C
Magnet lifting force in use – key factors
- Distance (between the magnet and the metal), because even a very small distance (e.g. 0.5 mm) results in a decrease in force by up to 50% (this also applies to paint, corrosion or dirt).
- Load vector – maximum parameter is reached only during pulling at a 90° angle. The force required to slide of the magnet along the plate is usually many times lower (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).
- Material composition – different alloys attracts identically. High carbon content weaken the interaction with the magnet.
- Surface finish – ideal contact is obtained only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
- Operating temperature – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under perpendicular forces, however under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Additionally, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.
Safety rules for work with neodymium magnets
Immense force
Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Be predictive.
Magnetic media
Intense magnetic fields can erase data on payment cards, HDDs, and storage devices. Keep a distance of min. 10 cm.
Combustion hazard
Drilling and cutting of neodymium magnets poses a fire hazard. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Medical implants
Medical warning: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have electronic implants.
Fragile material
Neodymium magnets are sintered ceramics, meaning they are prone to chipping. Collision of two magnets will cause them breaking into small pieces.
Power loss in heat
Do not overheat. Neodymium magnets are susceptible to heat. If you require resistance above 80°C, look for special high-temperature series (H, SH, UH).
Bone fractures
Risk of injury: The attraction force is so immense that it can cause hematomas, crushing, and even bone fractures. Protective gloves are recommended.
Skin irritation risks
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction occurs, immediately stop handling magnets and wear gloves.
GPS Danger
Be aware: neodymium magnets generate a field that disrupts sensitive sensors. Keep a separation from your phone, device, and navigation systems.
Product not for children
Neodymium magnets are not intended for children. Accidental ingestion of a few magnets can lead to them attracting across intestines, which poses a direct threat to life and requires urgent medical intervention.
