Advantages as well as disadvantages of Nd2Fe14B magnets.
Strengths
- They have unchanged lifting capacity, and over nearly ten years their performance decreases symbolically – ~1% (according to theory),
- Neodymium magnets are characterized by exceptionally resistant to demagnetization caused by external field sources,
- In other words, due to the glossy layer of nickel, the element looks attractive,
- Magnetic induction on the surface of the magnet is very high,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Possibility of custom shaping as well as optimizing to concrete conditions,
- Key role in future technologies – they are used in hard drives, drive modules, medical equipment, as well as complex engineering applications.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- At very strong impacts they can break, therefore we recommend placing them in special holders. 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 stability even at temperatures up to 230°C
- They oxidize in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- We recommend casing - magnetic holder, due to difficulties in realizing threads inside the magnet and complex forms.
- Potential hazard related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child safety. Furthermore, small components of these magnets are able to be problematic in diagnostics medical in case of swallowing.
- With mass production the cost of neodymium magnets is a challenge,
Holding force characteristics
Highest magnetic holding force – what contributes to it?
- with the use of a yoke made of special test steel, guaranteeing full magnetic saturation
- whose thickness reaches at least 10 mm
- with an ground touching surface
- under conditions of ideal adhesion (metal-to-metal)
- during detachment in a direction vertical to the plane
- at standard ambient temperature
Magnet lifting force in use – key factors
- Clearance – the presence of foreign body (rust, dirt, gap) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Force direction – catalog parameter refers to detachment vertically. When slipping, the magnet holds much less (often approx. 20-30% of maximum force).
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
- Material composition – different alloys reacts the same. Alloy additives weaken the attraction effect.
- Smoothness – ideal contact is possible only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
- Thermal factor – high temperature weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under shearing force the load capacity is reduced by as much as 5 times. Additionally, even a small distance between the magnet and the plate reduces the holding force.
Warnings
Dust explosion hazard
Mechanical processing of neodymium magnets carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Impact on smartphones
Be aware: neodymium magnets produce a field that disrupts sensitive sensors. Keep a separation from your mobile, tablet, and navigation systems.
Safe operation
Use magnets consciously. Their huge power can surprise even experienced users. Stay alert and respect their power.
This is not a toy
Strictly keep magnets away from children. Choking hazard is high, and the effects of magnets clamping inside the body are life-threatening.
Electronic devices
Do not bring magnets near a purse, laptop, or screen. The magnetism can destroy these devices and erase data from cards.
Maximum temperature
Standard neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. This process is irreversible.
Protective goggles
Protect your eyes. Magnets can explode upon violent connection, ejecting shards into the air. We recommend safety glasses.
Implant safety
For implant holders: Strong magnetic fields disrupt medical devices. Keep at least 30 cm distance or request help to work with the magnets.
Bone fractures
Big blocks can break fingers in a fraction of a second. Never place your hand betwixt two attracting surfaces.
Nickel allergy
Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If skin irritation happens, immediately stop working with magnets and wear gloves.
