Pros as well as cons of Nd2Fe14B magnets.
Benefits
- They have stable power, and over more than ten years their attraction force decreases symbolically – ~1% (according to theory),
- They have excellent resistance to weakening of magnetic properties when exposed to external magnetic sources,
- A magnet with a smooth nickel surface has better aesthetics,
- They are known for high magnetic induction at the operating surface, making them more effective,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to flexibility in forming and the ability to adapt to specific needs,
- Fundamental importance in innovative solutions – they are used in mass storage devices, drive modules, medical devices, as well as modern systems.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Disadvantages
- At very strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- When exposed to high temperature, neodymium magnets experience a drop in power. 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 suggest using waterproof magnets e.g. in rubber, plastic
- Limited ability of producing nuts in the magnet and complex forms - recommended is a housing - mounting mechanism.
- Potential hazard resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child health protection. It is also worth noting that small components of these devices can complicate diagnosis medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Maximum holding power of the magnet – what it depends on?
- on a plate made of mild steel, optimally conducting the magnetic field
- possessing a thickness of at least 10 mm to ensure full flux closure
- characterized by smoothness
- without any air gap between the magnet and steel
- under axial force vector (90-degree angle)
- in neutral thermal conditions
Determinants of lifting force in real conditions
- Gap (betwixt the magnet and the plate), since even a tiny distance (e.g. 0.5 mm) results in a decrease in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Material type – the best choice is high-permeability steel. Hardened steels may attract less.
- Surface quality – the more even the plate, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
- Temperature – temperature increase results in weakening of induction. Check the thermal limit for a given model.
Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under parallel forces the load capacity is reduced by as much as fivefold. In addition, even a small distance between the magnet and the plate reduces the load capacity.
H&S for magnets
This is not a toy
Absolutely keep magnets away from children. Risk of swallowing is high, and the consequences of magnets clamping inside the body are very dangerous.
Demagnetization risk
Do not overheat. NdFeB magnets are susceptible to heat. If you require resistance above 80°C, ask us about HT versions (H, SH, UH).
Dust is flammable
Mechanical processing of neodymium magnets poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Crushing risk
Big blocks can break fingers instantly. Do not place your hand between two strong magnets.
Compass and GPS
Note: neodymium magnets generate a field that confuses precision electronics. Maintain a separation from your mobile, device, and GPS.
Metal Allergy
Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If redness happens, immediately stop handling magnets and wear gloves.
Safe operation
Handle magnets consciously. Their immense force can surprise even professionals. Plan your moves and do not underestimate their power.
Electronic devices
Do not bring magnets close to a purse, computer, or screen. The magnetism can irreversibly ruin these devices and erase data from cards.
Pacemakers
Individuals with a pacemaker have to keep an safe separation from magnets. The magnetism can disrupt the functioning of the implant.
Protective goggles
Protect your eyes. Magnets can explode upon violent connection, launching sharp fragments into the air. Wear goggles.
