Strengths as well as weaknesses of neodymium magnets.
Strengths
- They have unchanged lifting capacity, and over more than ten years their attraction force decreases symbolically – ~1% (in testing),
- They are resistant to demagnetization induced by external magnetic fields,
- In other words, due to the aesthetic layer of nickel, the element looks attractive,
- 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 form) at temperatures up to 230°C and above...
- Possibility of detailed creating and optimizing to concrete applications,
- Wide application in modern technologies – they are commonly used in data components, drive modules, precision medical tools, as well as technologically advanced constructions.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Cons
- At very strong impacts they can crack, therefore we advise placing them in special holders. 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 power (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 - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Due to limitations in creating threads and complex forms in magnets, we propose using casing - magnetic holder.
- Possible danger resulting from small fragments of magnets pose a threat, in case of ingestion, which becomes key in the aspect of protecting the youngest. Furthermore, small elements of these magnets are able to be problematic in diagnostics medical after entering the body.
- Due to complex production process, their price is relatively high,
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what it depends on?
- on a base made of mild steel, optimally conducting the magnetic flux
- whose thickness reaches at least 10 mm
- with a plane free of scratches
- under conditions of no distance (metal-to-metal)
- during pulling in a direction vertical to the plane
- in temp. approx. 20°C
Key elements affecting lifting force
- Space between surfaces – every millimeter of separation (caused e.g. by veneer or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
- Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Metal type – different alloys attracts identically. Alloy additives weaken the attraction effect.
- Surface finish – ideal contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Heat – NdFeB sinters 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 the force acted perpendicularly, whereas under shearing force the holding force is lower. Moreover, even a slight gap between the magnet and the plate decreases the load capacity.
H&S for magnets
Handling rules
Be careful. Neodymium magnets attract from a long distance and snap with huge force, often faster than you can move away.
Mechanical processing
Machining of NdFeB material carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Permanent damage
Standard neodymium magnets (N-type) lose magnetization when the temperature goes above 80°C. This process is irreversible.
Warning for heart patients
Patients with a heart stimulator should maintain an safe separation from magnets. The magnetic field can interfere with the functioning of the implant.
Keep away from electronics
GPS units and mobile phones are extremely sensitive to magnetic fields. Close proximity with a strong magnet can decalibrate the sensors in your phone.
Crushing force
Pinching hazard: The attraction force is so immense that it can cause hematomas, crushing, and broken bones. Use thick gloves.
Beware of splinters
Despite the nickel coating, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Data carriers
Powerful magnetic fields can erase data on payment cards, hard drives, and other magnetic media. Stay away of at least 10 cm.
Product not for children
Strictly keep magnets away from children. Risk of swallowing is high, and the effects of magnets clamping inside the body are fatal.
Sensitization to coating
Some people suffer from a contact allergy to Ni, which is the typical protective layer for neodymium magnets. Prolonged contact might lead to an allergic reaction. We recommend use protective gloves.
