Strengths and weaknesses of Nd2Fe14B magnets.
Pros
- Their power is maintained, and after around ten years it decreases only by ~1% (theoretically),
- Neodymium magnets remain exceptionally resistant to magnetic field loss caused by external magnetic fields,
- Thanks to the smooth finish, the layer of nickel, gold-plated, or silver gives an clean appearance,
- Magnetic induction on the surface of the magnet is extremely intense,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
- Considering the option of flexible molding and customization to custom needs, NdFeB magnets can be modeled in a broad palette of shapes and sizes, which makes them more universal,
- Versatile presence in innovative solutions – they find application in computer drives, motor assemblies, advanced medical instruments, and other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which enables their usage in miniature devices
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a special holder, which not only protects them against impacts but also raises their durability
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (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 extremely resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- Limited possibility of producing nuts in the magnet and complicated shapes - preferred is casing - mounting mechanism.
- Potential hazard related to microscopic parts of magnets can be dangerous, in case of ingestion, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small components of these magnets are able to be problematic in diagnostics medical when they are in the body.
- Due to neodymium price, their price is higher than average,
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- using a plate made of high-permeability steel, acting as a ideal flux conductor
- with a cross-section of at least 10 mm
- characterized by lack of roughness
- under conditions of ideal adhesion (metal-to-metal)
- under axial application of breakaway force (90-degree angle)
- at standard ambient temperature
Practical lifting capacity: influencing factors
- Gap (betwixt the magnet and the metal), because even a microscopic distance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
- Loading method – catalog parameter refers to detachment vertically. When applying parallel force, the magnet holds much less (often approx. 20-30% of maximum force).
- Base massiveness – too thin steel does not close the flux, causing part of the flux to be lost into the air.
- Material composition – not every steel reacts the same. High carbon content weaken the interaction with the magnet.
- Smoothness – full contact is possible only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
- Thermal factor – high temperature weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was measured with the use of a smooth steel plate of suitable thickness (min. 20 mm), under vertically applied force, in contrast under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Additionally, even a small distance between the magnet’s surface and the plate reduces the lifting capacity.
Safe handling of NdFeB magnets
Danger to the youngest
Strictly keep magnets away from children. Risk of swallowing is high, and the effects of magnets clamping inside the body are life-threatening.
Pinching danger
Risk of injury: The pulling power is so immense that it can cause hematomas, crushing, and broken bones. Use thick gloves.
Metal Allergy
Studies show that nickel (standard magnet coating) is a common allergen. For allergy sufferers, refrain from touching magnets with bare hands or choose versions in plastic housing.
Material brittleness
Beware of splinters. Magnets can fracture upon violent connection, ejecting shards into the air. We recommend safety glasses.
Fire risk
Machining of neodymium magnets carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Respect the power
Handle magnets with awareness. Their huge power can surprise even experienced users. Plan your moves and do not underestimate their force.
GPS and phone interference
A strong magnetic field disrupts the functioning of magnetometers in smartphones and navigation systems. Do not bring magnets close to a smartphone to prevent damaging the sensors.
Medical interference
Warning for patients: Strong magnetic fields affect electronics. Maintain minimum 30 cm distance or request help to handle the magnets.
Keep away from computers
Intense magnetic fields can erase data on payment cards, HDDs, and other magnetic media. Stay away of min. 10 cm.
Thermal limits
Avoid heat. NdFeB magnets are sensitive to temperature. If you require operation above 80°C, look for special high-temperature series (H, SH, UH).
