Advantages as well as disadvantages of Nd2Fe14B magnets.
Pros
- They have constant strength, and over around ten years their attraction force decreases symbolically – ~1% (according to theory),
- Neodymium magnets are exceptionally resistant to magnetic field loss caused by external field sources,
- In other words, due to the reflective surface of nickel, the element looks attractive,
- Magnetic induction on the surface of the magnet turns out to be impressive,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
- Possibility of individual creating and optimizing to precise applications,
- Huge importance in electronics industry – they serve a role in magnetic memories, electric drive systems, medical equipment, and multitasking production systems.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Disadvantages
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a special holder, which not only secures them against impacts but also increases their durability
- NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (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 very resistant to heat
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Limited possibility of creating nuts in the magnet and complex shapes - preferred is cover - mounting mechanism.
- Possible danger resulting from small fragments of magnets pose a threat, if swallowed, which becomes key in the aspect of protecting the youngest. Additionally, small components of these magnets are able to complicate diagnosis medical after entering the body.
- Due to neodymium price, their price is relatively high,
Holding force characteristics
Detachment force of the magnet in optimal conditions – what it depends on?
- using a base made of low-carbon steel, serving as a circuit closing element
- possessing a thickness of min. 10 mm to ensure full flux closure
- with an ideally smooth touching surface
- without the slightest air gap between the magnet and steel
- for force acting at a right angle (in the magnet axis)
- in temp. approx. 20°C
Impact of factors on magnetic holding capacity in practice
- Space between surfaces – every millimeter of distance (caused e.g. by veneer or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
- Loading method – catalog parameter refers to pulling vertically. When applying parallel force, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
- Metal type – not every steel reacts the same. High carbon content weaken the attraction effect.
- Plate texture – smooth surfaces ensure maximum contact, which improves force. Uneven metal reduce efficiency.
- Heat – NdFeB sinters have a sensitivity to temperature. At higher temperatures they are weaker, and in frost gain strength (up to a certain limit).
Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under shearing force the lifting capacity is smaller. In addition, even a slight gap between the magnet and the plate lowers the lifting capacity.
Precautions when working with neodymium magnets
ICD Warning
People with a heart stimulator have to maintain an absolute distance from magnets. The magnetic field can interfere with the functioning of the life-saving device.
Handling rules
Before use, check safety instructions. Sudden snapping can break the magnet or injure your hand. Be predictive.
Protective goggles
Protect your eyes. Magnets can fracture upon violent connection, launching sharp fragments into the air. Wear goggles.
Demagnetization risk
Avoid heat. NdFeB magnets are susceptible to heat. If you require resistance above 80°C, look for special high-temperature series (H, SH, UH).
Protect data
Equipment safety: Neodymium magnets can ruin data carriers and delicate electronics (pacemakers, medical aids, timepieces).
Bodily injuries
Pinching hazard: The attraction force is so immense that it can result in blood blisters, crushing, and broken bones. Protective gloves are recommended.
Avoid contact if allergic
Nickel alert: The nickel-copper-nickel coating contains nickel. If redness appears, immediately stop handling magnets and wear gloves.
Combustion hazard
Machining of NdFeB material poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Phone sensors
Navigation devices and mobile phones are extremely sensitive to magnetic fields. Close proximity with a strong magnet can ruin the sensors in your phone.
No play value
These products are not suitable for play. Swallowing several magnets may result in them connecting inside the digestive tract, which constitutes a direct threat to life and requires urgent medical intervention.
