Pros as well as cons of neodymium magnets.
Pros
- They have unchanged lifting capacity, and over more than 10 years their attraction force decreases symbolically – ~1% (according to theory),
- They retain their magnetic properties even under strong external field,
- In other words, due to the smooth layer of gold, the element is aesthetically pleasing,
- The surface of neodymium magnets generates a concentrated magnetic field – this is a key feature,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures reaching 230°C and above...
- In view of the option of precise molding and adaptation to unique solutions, NdFeB magnets can be created in a wide range of forms and dimensions, which amplifies use scope,
- Versatile presence in electronics industry – they are utilized in computer drives, electric drive systems, advanced medical instruments, and technologically advanced constructions.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Disadvantages
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
- NdFeB magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape as well as 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- Limited possibility of producing threads in the magnet and complex shapes - recommended is casing - magnet mounting.
- Possible danger to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child health protection. It is also worth noting that tiny parts of these products are able to be problematic in diagnostics medical after entering the body.
- With budget limitations the cost of neodymium magnets is economically unviable,
Holding force characteristics
Maximum lifting force for a neodymium magnet – what affects it?
- with the application of a sheet made of special test steel, guaranteeing maximum field concentration
- with a thickness of at least 10 mm
- with a surface perfectly flat
- without the slightest clearance between the magnet and steel
- under vertical force vector (90-degree angle)
- at standard ambient temperature
Practical lifting capacity: influencing factors
- Distance (betwixt the magnet and the metal), because even a microscopic clearance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to paint, rust or dirt).
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
- Plate material – mild steel attracts best. Higher carbon content decrease magnetic permeability and lifting capacity.
- Smoothness – full contact is obtained only on polished steel. Rough texture create air cushions, weakening the magnet.
- Thermal factor – hot environment weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under shearing force the lifting capacity is smaller. In addition, even a slight gap between the magnet and the plate lowers the lifting capacity.
H&S for magnets
No play value
Always store magnets out of reach of children. Ingestion danger is high, and the consequences of magnets clamping inside the body are very dangerous.
Allergic reactions
It is widely known that nickel (the usual finish) is a potent allergen. For allergy sufferers, avoid direct skin contact or select coated magnets.
Shattering risk
Despite the nickel coating, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Flammability
Mechanical processing of neodymium magnets poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Serious injuries
Watch your fingers. Two large magnets will join immediately with a force of massive weight, destroying everything in their path. Exercise extreme caution!
Electronic devices
Powerful magnetic fields can destroy records on payment cards, hard drives, and other magnetic media. Maintain a gap of min. 10 cm.
Life threat
Warning for patients: Strong magnetic fields affect medical devices. Maintain minimum 30 cm distance or request help to work with the magnets.
Thermal limits
Standard neodymium magnets (grade N) undergo demagnetization when the temperature goes above 80°C. This process is irreversible.
Threat to navigation
An intense magnetic field interferes with the functioning of magnetometers in phones and GPS navigation. Do not bring magnets close to a device to avoid damaging the sensors.
Do not underestimate power
Exercise caution. Neodymium magnets attract from a long distance and connect with massive power, often quicker than you can react.
