Pros as well as cons of Nd2Fe14B magnets.
Benefits
- They virtually do not lose power, because even after 10 years the performance loss is only ~1% (based on calculations),
- Magnets perfectly protect themselves against loss of magnetization caused by external fields,
- Thanks to the reflective finish, the surface of nickel, gold, or silver gives an clean appearance,
- The surface of neodymium magnets generates a unique magnetic field – this is a distinguishing feature,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for action at temperatures approaching 230°C and above...
- Possibility of individual modeling and optimizing to complex conditions,
- Universal use in modern industrial fields – they are utilized in computer drives, motor assemblies, precision medical tools, and complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which allows their use in compact constructions
Disadvantages
- At very strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- They oxidize in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Due to limitations in creating nuts and complex shapes in magnets, we propose using casing - magnetic mount.
- Possible danger to health – tiny shards of magnets pose a threat, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Additionally, tiny parts of these magnets can disrupt the diagnostic process medical when they are in the body.
- Due to complex production process, their price is relatively high,
Holding force characteristics
Best holding force of the magnet in ideal parameters – what it depends on?
- on a plate made of mild steel, optimally conducting the magnetic field
- possessing a massiveness of min. 10 mm to ensure full flux closure
- with an polished touching surface
- under conditions of gap-free contact (surface-to-surface)
- during detachment in a direction vertical to the mounting surface
- in stable room temperature
Practical lifting capacity: influencing factors
- Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Force direction – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
- Steel grade – the best choice is high-permeability steel. Stainless steels may have worse magnetic properties.
- Surface finish – full contact is possible only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
- Temperature – temperature increase results in weakening of force. It is worth remembering the thermal limit for a given model.
Lifting capacity was measured with the use of a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, whereas under shearing force the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate reduces the load capacity.
Safety rules for work with neodymium magnets
Dust is flammable
Powder produced during cutting of magnets is combustible. Do not drill into magnets unless you are an expert.
Allergy Warning
Allergy Notice: The nickel-copper-nickel coating contains nickel. If an allergic reaction occurs, cease handling magnets and use protective gear.
Pinching danger
Large magnets can smash fingers in a fraction of a second. Under no circumstances place your hand betwixt two strong magnets.
Permanent damage
Regular neodymium magnets (grade N) lose power when the temperature exceeds 80°C. This process is irreversible.
Handling guide
Handle magnets consciously. Their huge power can shock even experienced users. Plan your moves and respect their force.
This is not a toy
Always store magnets away from children. Choking hazard is high, and the effects of magnets connecting inside the body are life-threatening.
Electronic hazard
Do not bring magnets near a purse, computer, or TV. The magnetism can destroy these devices and erase data from cards.
Beware of splinters
Neodymium magnets are ceramic materials, meaning they are very brittle. Impact of two magnets will cause them shattering into small pieces.
GPS Danger
Be aware: rare earth magnets produce a field that confuses sensitive sensors. Keep a safe distance from your phone, tablet, and GPS.
Medical implants
Life threat: Strong magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.
