Strengths and weaknesses of neodymium magnets.
Benefits
- They have unchanged lifting capacity, and over more than ten years their attraction force decreases symbolically – ~1% (in testing),
- Magnets very well defend themselves against loss of magnetization caused by ambient magnetic noise,
- The use of an shiny layer of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Magnetic induction on the working layer of the magnet turns out to be very high,
- Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to freedom in shaping and the capacity to customize to complex applications,
- Versatile presence in advanced technology sectors – they are utilized in computer drives, electric drive systems, diagnostic systems, and other advanced devices.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a steel housing, which not only protects them against impacts but also increases their durability
- Neodymium magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (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
- They rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- We suggest casing - magnetic mechanism, due to difficulties in producing nuts inside the magnet and complex forms.
- Potential hazard to health – tiny shards of magnets can be dangerous, in case of ingestion, which becomes key in the context of child safety. Furthermore, small elements of these magnets are able to be problematic in diagnostics medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Best holding force of the magnet in ideal parameters – what it depends on?
- with the use of a yoke made of low-carbon steel, guaranteeing maximum field concentration
- possessing a massiveness of min. 10 mm to ensure full flux closure
- characterized by lack of roughness
- with zero gap (without paint)
- during detachment in a direction perpendicular to the mounting surface
- at ambient temperature approx. 20 degrees Celsius
Magnet lifting force in use – key factors
- Clearance – the presence of any layer (rust, dirt, air) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Load vector – maximum parameter is available only during pulling at a 90° angle. The shear force of the magnet along the plate is standardly many times smaller (approx. 1/5 of the lifting capacity).
- Plate thickness – too thin sheet does not close the flux, causing part of the flux to be wasted to the other side.
- Plate material – mild steel gives the best results. Alloy steels lower magnetic properties and holding force.
- Surface quality – the more even the plate, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
- Temperature influence – hot environment reduces magnetic field. Exceeding the limit 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, in contrast under shearing force the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate decreases the holding force.
Warnings
Compass and GPS
A powerful magnetic field disrupts the functioning of compasses in phones and navigation systems. Keep magnets close to a device to prevent breaking the sensors.
Demagnetization risk
Control the heat. Exposing the magnet above 80 degrees Celsius will permanently weaken its properties and strength.
Fire risk
Machining of NdFeB material poses a fire hazard. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Health Danger
People with a ICD have to keep an large gap from magnets. The magnetism can stop the operation of the life-saving device.
Handling rules
Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Be predictive.
Choking Hazard
Product intended for adults. Small elements pose a choking risk, causing intestinal necrosis. Keep away from children and animals.
Electronic hazard
Do not bring magnets near a wallet, laptop, or screen. The magnetism can irreversibly ruin these devices and erase data from cards.
Bone fractures
Large magnets can break fingers in a fraction of a second. Do not place your hand between two attracting surfaces.
Material brittleness
Protect your eyes. Magnets can explode upon violent connection, ejecting shards into the air. We recommend safety glasses.
Avoid contact if allergic
Nickel alert: The nickel-copper-nickel coating contains nickel. If redness occurs, cease handling magnets and use protective gear.
