Pros and cons of rare earth magnets.
Strengths
- They have unchanged lifting capacity, and over more than ten years their attraction force decreases symbolically – ~1% (according to theory),
- They do not lose their magnetic properties even under close interference source,
- In other words, due to the aesthetic surface of silver, the element is aesthetically pleasing,
- Magnets have huge magnetic induction on the working surface,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to freedom in forming and the ability to modify to specific needs,
- Key role in modern industrial fields – they are used in HDD drives, brushless drives, advanced medical instruments, also modern systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Cons
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also improves its resistance to damage
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (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 while using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- We recommend casing - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complicated forms.
- Possible danger to health – tiny shards of magnets are risky, in case of ingestion, which becomes key in the context of child safety. Additionally, tiny parts of these magnets are able to complicate diagnosis medical when they are in the body.
- Due to complex production process, their price exceeds standard values,
Holding force characteristics
Maximum magnetic pulling force – what it depends on?
- on a block made of structural steel, optimally conducting the magnetic flux
- possessing a thickness of minimum 10 mm to avoid saturation
- with an ideally smooth touching surface
- without any clearance between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- at room temperature
Practical lifting capacity: influencing factors
- Gap (between the magnet and the metal), because even a very small distance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
- Direction of force – maximum parameter is obtained only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is usually several times lower (approx. 1/5 of the lifting capacity).
- Base massiveness – insufficiently thick plate does not close the flux, causing part of the flux to be escaped to the other side.
- Steel grade – the best choice is pure iron steel. Cast iron may attract less.
- Smoothness – full contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Temperature – heating the magnet causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, in contrast under parallel forces the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate reduces the load capacity.
Safe handling of neodymium magnets
Sensitization to coating
Allergy Notice: The nickel-copper-nickel coating contains nickel. If redness happens, immediately stop working with magnets and wear gloves.
Fire risk
Powder created during grinding of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
Powerful field
Use magnets consciously. Their immense force can surprise even experienced users. Stay alert and respect their force.
Risk of cracking
Watch out for shards. Magnets can explode upon uncontrolled impact, ejecting shards into the air. We recommend safety glasses.
Demagnetization risk
Standard neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. The loss of strength is permanent.
Keep away from computers
Do not bring magnets near a wallet, laptop, or TV. The magnetism can destroy these devices and erase data from cards.
Finger safety
Protect your hands. Two powerful magnets will snap together immediately with a force of massive weight, destroying anything in their path. Exercise extreme caution!
Do not give to children
NdFeB magnets are not intended for children. Accidental ingestion of multiple magnets can lead to them attracting across intestines, which poses a severe health hazard and requires immediate surgery.
ICD Warning
For implant holders: Powerful magnets affect electronics. Keep at least 30 cm distance or request help to work with the magnets.
Compass and GPS
Navigation devices and mobile phones are highly sensitive to magnetic fields. Close proximity with a strong magnet can decalibrate the internal compass in your phone.
