Pros and cons of Nd2Fe14B magnets.
Pros
- Their power is durable, and after around ten years it decreases only by ~1% (according to research),
- They feature excellent resistance to weakening of magnetic properties due to external fields,
- In other words, due to the metallic layer of gold, the element gains visual value,
- They show high magnetic induction at the operating surface, making them more effective,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
- Thanks to modularity in forming and the capacity to customize to specific needs,
- Universal use in high-tech industry – they serve a role in data components, electromotive mechanisms, diagnostic systems, also other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which enables their usage in miniature devices
Weaknesses
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also improves its resistance to damage
- NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (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 extremely resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- Due to limitations in realizing nuts and complicated forms in magnets, we recommend using a housing - magnetic mount.
- Potential hazard 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 magnets are able to complicate diagnosis medical in case of swallowing.
- With large orders the cost of neodymium magnets is a challenge,
Lifting parameters
Maximum lifting force for a neodymium magnet – what contributes to it?
- using a sheet made of low-carbon steel, serving as a ideal flux conductor
- whose transverse dimension reaches at least 10 mm
- with an polished touching surface
- under conditions of no distance (metal-to-metal)
- during pulling in a direction perpendicular to the plane
- at temperature room level
Magnet lifting force in use – key factors
- Space between surfaces – even a fraction of a millimeter of distance (caused e.g. by varnish or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Force direction – declared lifting capacity refers to detachment vertically. When slipping, the magnet holds much less (often approx. 20-30% of nominal force).
- Plate thickness – insufficiently thick steel causes magnetic saturation, causing part of the power to be wasted into the air.
- Chemical composition of the base – low-carbon steel gives the best results. Higher carbon content lower magnetic permeability and lifting capacity.
- Surface structure – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Unevenness creates an air distance.
- Temperature – heating the magnet causes a temporary drop of induction. Check the thermal limit for a given model.
Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 75%. Moreover, even a small distance between the magnet’s surface and the plate reduces the lifting capacity.
Warnings
Keep away from children
Product intended for adults. Tiny parts can be swallowed, leading to serious injuries. Keep away from kids and pets.
Nickel allergy
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If redness occurs, cease working with magnets and use protective gear.
Medical interference
Patients with a heart stimulator should keep an absolute distance from magnets. The magnetic field can disrupt the functioning of the life-saving device.
Magnet fragility
Watch out for shards. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. Wear goggles.
Dust explosion hazard
Mechanical processing of NdFeB material poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Do not overheat magnets
Regular neodymium magnets (grade N) lose power when the temperature exceeds 80°C. The loss of strength is permanent.
Respect the power
Exercise caution. Rare earth magnets act from a distance and snap with massive power, often quicker than you can move away.
Precision electronics
Navigation devices and mobile phones are highly susceptible to magnetic fields. Close proximity with a strong magnet can decalibrate the internal compass in your phone.
Crushing force
Big blocks can crush fingers in a fraction of a second. Under no circumstances place your hand betwixt two attracting surfaces.
Electronic hazard
Very strong magnetic fields can destroy records on credit cards, hard drives, and storage devices. Stay away of at least 10 cm.
