Advantages and disadvantages of Nd2Fe14B magnets.
Advantages
- They have unchanged lifting capacity, and over around 10 years their performance decreases symbolically – ~1% (according to theory),
- They are noted for resistance to demagnetization induced by external field influence,
- A magnet with a shiny silver surface has an effective appearance,
- They feature high magnetic induction at the operating surface, which affects their effectiveness,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Thanks to flexibility in forming and the capacity to modify to client solutions,
- Wide application in future technologies – they are commonly used in magnetic memories, drive modules, diagnostic systems, and complex engineering applications.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Weaknesses
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only shields the magnet but also increases its resistance to damage
- When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their strength 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 rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- We recommend casing - magnetic holder, due to difficulties in creating threads inside the magnet and complex forms.
- Possible danger related to microscopic parts of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that small elements of these devices can be problematic in diagnostics medical after entering the body.
- Due to expensive raw materials, their price is higher than average,
Pull force analysis
Detachment force of the magnet in optimal conditions – what it depends on?
- with the application of a yoke made of special test steel, ensuring full magnetic saturation
- possessing a massiveness of min. 10 mm to ensure full flux closure
- with a surface cleaned and smooth
- with direct contact (without impurities)
- during pulling in a direction perpendicular to the plane
- at conditions approx. 20°C
Magnet lifting force in use – key factors
- Distance (between the magnet and the plate), since even a microscopic distance (e.g. 0.5 mm) results in a drastic drop in lifting capacity by up to 50% (this also applies to paint, rust or dirt).
- Angle of force application – maximum parameter is available only during pulling at a 90° angle. The force required to slide of the magnet along the surface is typically several times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of generating force.
- Plate material – low-carbon steel gives the best results. Alloy admixtures lower magnetic permeability and lifting capacity.
- Surface condition – smooth surfaces ensure maximum contact, which improves field saturation. Rough surfaces reduce efficiency.
- Thermal factor – high temperature reduces pulling force. Too high temperature can permanently damage the magnet.
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a small distance between the magnet’s surface and the plate reduces the lifting capacity.
H&S for magnets
Pacemakers
For implant holders: Strong magnetic fields disrupt medical devices. Keep at least 30 cm distance or ask another person to work with the magnets.
Magnet fragility
Beware of splinters. Magnets can fracture upon violent connection, ejecting shards into the air. Wear goggles.
Dust is flammable
Powder generated during grinding of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
Serious injuries
Pinching hazard: The attraction force is so immense that it can result in blood blisters, crushing, and even bone fractures. Use thick gloves.
Heat sensitivity
Standard neodymium magnets (grade N) lose power when the temperature surpasses 80°C. Damage is permanent.
Electronic hazard
Very strong magnetic fields can destroy records on credit cards, hard drives, and storage devices. Keep a distance of at least 10 cm.
Allergic reactions
Allergy Notice: The nickel-copper-nickel coating consists of nickel. If skin irritation appears, cease handling magnets and use protective gear.
Adults only
Absolutely store magnets out of reach of children. Risk of swallowing is significant, and the consequences of magnets connecting inside the body are tragic.
Conscious usage
Handle magnets with awareness. Their powerful strength can surprise even professionals. Be vigilant and do not underestimate their power.
GPS and phone interference
A powerful magnetic field disrupts the functioning of compasses in smartphones and navigation systems. Maintain magnets near a device to avoid breaking the sensors.
