Pros as well as cons of Nd2Fe14B magnets.
Benefits
- They have constant strength, and over nearly ten years their attraction force decreases symbolically – ~1% (according to theory),
- Magnets effectively resist against demagnetization caused by ambient magnetic noise,
- By applying a decorative coating of nickel, the element presents an aesthetic look,
- The surface of neodymium magnets generates a intense magnetic field – this is one of their assets,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to flexibility in designing and the ability to customize to specific needs,
- Universal use in modern industrial fields – they serve a role in computer drives, electromotive mechanisms, precision medical tools, as well as multitasking production systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Cons
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a special holder, which not only secures them against impacts but also increases their durability
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in producing nuts and complicated shapes in magnets, we recommend using casing - magnetic mechanism.
- Health risk related to microscopic parts of magnets are risky, if swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that tiny parts of these magnets can complicate diagnosis medical when they are in the body.
- With mass production the cost of neodymium magnets is economically unviable,
Lifting parameters
Maximum magnetic pulling force – what it depends on?
- on a block made of structural steel, optimally conducting the magnetic flux
- whose transverse dimension reaches at least 10 mm
- characterized by lack of roughness
- without the slightest clearance between the magnet and steel
- under perpendicular force vector (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Determinants of practical lifting force of a magnet
- Air gap (between the magnet and the metal), as even a microscopic clearance (e.g. 0.5 mm) results in a drastic drop in force by up to 50% (this also applies to varnish, corrosion or dirt).
- Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
- Material composition – different alloys attracts identically. High carbon content worsen the interaction with the magnet.
- Surface condition – smooth surfaces guarantee perfect abutment, which increases force. Uneven metal weaken the grip.
- Temperature influence – high temperature reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.
Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Additionally, even a small distance between the magnet’s surface and the plate decreases the holding force.
Safety rules for work with neodymium magnets
GPS Danger
Remember: rare earth magnets generate a field that confuses precision electronics. Maintain a separation from your phone, tablet, and navigation systems.
Magnetic media
Do not bring magnets close to a wallet, laptop, or TV. The magnetism can irreversibly ruin these devices and erase data from cards.
Nickel allergy
Studies show that nickel (the usual finish) is a potent allergen. For allergy sufferers, avoid touching magnets with bare hands and choose versions in plastic housing.
Permanent damage
Do not overheat. NdFeB magnets are susceptible to heat. If you need resistance above 80°C, ask us about HT versions (H, SH, UH).
Risk of cracking
Despite the nickel coating, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.
Combustion hazard
Drilling and cutting of neodymium magnets carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
This is not a toy
Neodymium magnets are not toys. Eating a few magnets can lead to them connecting inside the digestive tract, which poses a critical condition and necessitates immediate surgery.
Physical harm
Big blocks can crush fingers in a fraction of a second. Under no circumstances put your hand betwixt two strong magnets.
Life threat
Warning for patients: Strong magnetic fields affect medical devices. Keep at least 30 cm distance or ask another person to work with the magnets.
Do not underestimate power
Handle with care. Neodymium magnets attract from a long distance and snap with massive power, often quicker than you can react.
