Advantages and disadvantages of rare earth magnets.
Pros
- Their magnetic field remains stable, and after around ten years it decreases only by ~1% (theoretically),
- Neodymium magnets remain highly resistant to magnetic field loss caused by magnetic disturbances,
- The use of an aesthetic layer of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- Neodymium magnets create maximum magnetic induction on a small area, which allows for strong attraction,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for operation at temperatures reaching 230°C and above...
- Possibility of detailed creating and modifying to individual applications,
- Fundamental importance in advanced technology sectors – they are used in magnetic memories, electromotive mechanisms, medical equipment, as well as complex engineering applications.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Limitations
- To avoid cracks under impact, we recommend using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
- Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- They oxidize in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Due to limitations in creating threads and complicated shapes in magnets, we recommend using casing - magnetic mount.
- Potential hazard resulting from small fragments of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small components of these devices are able to disrupt the diagnostic process medical in case of swallowing.
- Due to complex production process, their price exceeds standard values,
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what it depends on?
- on a block made of structural steel, optimally conducting the magnetic flux
- whose thickness equals approx. 10 mm
- with a surface perfectly flat
- without any insulating layer between the magnet and steel
- during detachment in a direction perpendicular to the plane
- at ambient temperature approx. 20 degrees Celsius
Lifting capacity in practice – influencing factors
- Gap between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Force direction – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Chemical composition of the base – mild steel attracts best. Higher carbon content lower magnetic permeability and lifting capacity.
- Surface structure – the more even the plate, the larger the contact zone and stronger the hold. Roughness creates an air distance.
- Temperature – temperature increase causes a temporary drop of force. Check the maximum operating temperature for a given model.
Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, 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
Thermal limits
Control the heat. Exposing the magnet above 80 degrees Celsius will destroy its properties and strength.
Danger to the youngest
Always store magnets away from children. Choking hazard is significant, and the consequences of magnets clamping inside the body are fatal.
Bone fractures
Large magnets can crush fingers in a fraction of a second. Never put your hand between two attracting surfaces.
Magnet fragility
NdFeB magnets are sintered ceramics, which means they are prone to chipping. Collision of two magnets will cause them shattering into small pieces.
Handling guide
Handle magnets with awareness. Their huge power can surprise even professionals. Stay alert and do not underestimate their power.
Dust is flammable
Dust generated during cutting of magnets is combustible. Do not drill into magnets unless you are an expert.
Implant safety
For implant holders: Powerful magnets disrupt electronics. Keep at least 30 cm distance or request help to work with the magnets.
Electronic hazard
Data protection: Strong magnets can damage payment cards and sensitive devices (heart implants, hearing aids, mechanical watches).
Allergy Warning
Allergy Notice: The nickel-copper-nickel coating contains nickel. If skin irritation happens, immediately stop working with magnets and wear gloves.
Compass and GPS
A strong magnetic field negatively affects the functioning of compasses in smartphones and navigation systems. Do not bring magnets near a device to prevent damaging the sensors.
