Pros and cons of rare earth magnets.
Benefits
- They retain full power for almost ten years – the drop is just ~1% (according to analyses),
- They retain their magnetic properties even under close interference source,
- A magnet with a metallic silver surface looks better,
- They show high magnetic induction at the operating surface, which affects their effectiveness,
- 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...
- Thanks to flexibility in constructing and the capacity to adapt to complex applications,
- Versatile presence in advanced technology sectors – they serve a role in HDD drives, electric drive systems, medical devices, as well as complex engineering applications.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Cons
- At very strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material protecting against moisture
- We recommend a housing - magnetic holder, due to difficulties in producing nuts inside the magnet and complicated shapes.
- Potential hazard to health – tiny shards of magnets are risky, if swallowed, which becomes key in the context of child health protection. Furthermore, small elements of these magnets can disrupt the diagnostic process medical after entering the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Pull force analysis
Maximum lifting force for a neodymium magnet – what affects it?
- with the use of a yoke made of low-carbon steel, guaranteeing maximum field concentration
- possessing a thickness of minimum 10 mm to avoid saturation
- with an ground touching surface
- with total lack of distance (without paint)
- under vertical force vector (90-degree angle)
- at standard ambient temperature
Practical aspects of lifting capacity – factors
- Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by varnish or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Direction of force – highest force is available only during perpendicular pulling. The shear force of the magnet along the surface is typically several times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Metal type – not every steel reacts the same. Alloy additives weaken the attraction effect.
- Smoothness – ideal contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
- Heat – NdFeB sinters have a sensitivity to temperature. At higher temperatures they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under attempts to slide the magnet the holding force is lower. Moreover, even a small distance between the magnet and the plate decreases the load capacity.
Safe handling of NdFeB magnets
Shattering risk
Despite the nickel coating, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
Allergy Warning
A percentage of the population experience a hypersensitivity to Ni, which is the standard coating for neodymium magnets. Prolonged contact may cause skin redness. We recommend use protective gloves.
Precision electronics
Navigation devices and smartphones are highly susceptible to magnetic fields. Direct contact with a strong magnet can ruin the sensors in your phone.
Power loss in heat
Keep cool. Neodymium magnets are sensitive to heat. If you need resistance above 80°C, look for special high-temperature series (H, SH, UH).
Handling rules
Handle magnets with awareness. Their immense force can shock even experienced users. Plan your moves and do not underestimate their power.
Keep away from computers
Do not bring magnets close to a wallet, computer, or TV. The magnetism can permanently damage these devices and wipe information from cards.
Danger to the youngest
Adult use only. Small elements pose a choking risk, causing severe trauma. Keep out of reach of kids and pets.
Implant safety
Individuals with a ICD should maintain an large gap from magnets. The magnetism can disrupt the operation of the life-saving device.
Hand protection
Watch your fingers. Two powerful magnets will snap together instantly with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!
Fire warning
Machining of neodymium magnets poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
