Pros and cons of rare earth magnets.
Strengths
- They do not lose strength, even during nearly ten years – the drop in lifting capacity is only ~1% (theoretically),
- They maintain their magnetic properties even under external field action,
- The use of an elegant finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- The surface of neodymium magnets generates a concentrated magnetic field – this is one of their assets,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
- Thanks to the possibility of precise forming and customization to unique requirements, magnetic components can be produced in a wide range of geometric configurations, which increases their versatility,
- Key role in innovative solutions – they serve a role in mass storage devices, electromotive mechanisms, precision medical tools, and technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which enables their usage in miniature devices
Weaknesses
- To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
- Neodymium magnets lose their force 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 stability even at temperatures up to 230°C
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- We suggest a housing - magnetic mount, due to difficulties in realizing threads inside the magnet and complicated shapes.
- Potential hazard related to microscopic parts of magnets pose a threat, if swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, small elements of these devices are able to complicate diagnosis medical when they are in the body.
- With large orders the cost of neodymium magnets is economically unviable,
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what affects it?
- on a block made of mild steel, optimally conducting the magnetic flux
- whose transverse dimension equals approx. 10 mm
- with an ground contact surface
- under conditions of ideal adhesion (surface-to-surface)
- for force applied at a right angle (pull-off, not shear)
- at room temperature
Practical aspects of lifting capacity – factors
- Distance – the presence of foreign body (paint, dirt, gap) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
- Load vector – maximum parameter is reached only during perpendicular pulling. The force required to slide of the magnet along the plate is usually several times lower (approx. 1/5 of the lifting capacity).
- Substrate thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
- Material composition – not every steel attracts identically. Alloy additives weaken the interaction with the magnet.
- Base smoothness – the more even the surface, the better the adhesion and higher the lifting capacity. Unevenness creates an air distance.
- Temperature – heating the magnet results in weakening of force. It is worth remembering the thermal limit for a given model.
Lifting capacity was measured by applying a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, whereas under parallel forces the holding force is lower. In addition, even a slight gap between the magnet and the plate reduces the load capacity.
Safety rules for work with NdFeB magnets
Warning for heart patients
Health Alert: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.
Cards and drives
Powerful magnetic fields can destroy records on credit cards, hard drives, and other magnetic media. Stay away of min. 10 cm.
Protective goggles
Watch out for shards. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. Eye protection is mandatory.
GPS and phone interference
Note: rare earth magnets produce a field that disrupts sensitive sensors. Maintain a separation from your phone, device, and GPS.
Allergy Warning
It is widely known that the nickel plating (the usual finish) is a potent allergen. For allergy sufferers, refrain from direct skin contact or select versions in plastic housing.
Caution required
Handle magnets with awareness. Their huge power can shock even experienced users. Plan your moves and do not underestimate their force.
Finger safety
Mind your fingers. Two powerful magnets will snap together instantly with a force of massive weight, destroying anything in their path. Be careful!
Heat sensitivity
Keep cool. NdFeB magnets are susceptible to temperature. If you require operation above 80°C, look for special high-temperature series (H, SH, UH).
Flammability
Fire warning: Rare earth powder is highly flammable. Do not process magnets in home conditions as this risks ignition.
Keep away from children
Product intended for adults. Small elements pose a choking risk, causing severe trauma. Keep away from kids and pets.
