Strengths and weaknesses of rare earth magnets.
Pros
- They do not lose strength, even over nearly ten years – the reduction in power is only ~1% (theoretically),
- Magnets effectively resist against demagnetization caused by ambient magnetic noise,
- By covering with a reflective layer of silver, the element has an professional look,
- They feature high magnetic induction at the operating surface, making them more effective,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Considering the option of flexible shaping and adaptation to unique needs, NdFeB magnets can be created in a wide range of forms and dimensions, which increases their versatility,
- Versatile presence in modern industrial fields – they are utilized in magnetic memories, electric drive systems, advanced medical instruments, as well as other advanced devices.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Limitations
- They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
- Neodymium magnets decrease 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 durability even at temperatures up to 230°C
- They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Due to limitations in producing threads and complicated shapes in magnets, we recommend using cover - magnetic mechanism.
- Possible danger related to microscopic parts of magnets can be dangerous, if swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that tiny parts of these magnets are able to complicate diagnosis medical after entering the body.
- With large orders the cost of neodymium magnets is a challenge,
Pull force analysis
Maximum holding power of the magnet – what it depends on?
- with the use of a yoke made of special test steel, guaranteeing maximum field concentration
- possessing a thickness of minimum 10 mm to avoid saturation
- with an ideally smooth touching surface
- without the slightest clearance between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- at ambient temperature room level
What influences lifting capacity in practice
- Gap between magnet and steel – every millimeter of separation (caused e.g. by veneer or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Angle of force application – highest force is obtained only during perpendicular pulling. The resistance to sliding of the magnet along the plate is standardly several times lower (approx. 1/5 of the lifting capacity).
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
- Chemical composition of the base – mild steel gives the best results. Higher carbon content lower magnetic properties and holding force.
- Surface quality – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
- Thermal environment – temperature increase results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity was assessed with the use of a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, however under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a slight gap between the magnet and the plate reduces the load capacity.
Precautions when working with neodymium magnets
ICD Warning
Medical warning: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.
Product not for children
Neodymium magnets are not suitable for play. Swallowing a few magnets may result in them connecting inside the digestive tract, which poses a severe health hazard and necessitates immediate surgery.
Heat sensitivity
Keep cool. NdFeB magnets are susceptible to heat. If you need operation above 80°C, ask us about special high-temperature series (H, SH, UH).
Nickel coating and allergies
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction happens, cease working with magnets and wear gloves.
Threat to navigation
A strong magnetic field interferes with the functioning of compasses in phones and navigation systems. Do not bring magnets near a device to prevent damaging the sensors.
Protect data
Equipment safety: Neodymium magnets can ruin payment cards and delicate electronics (heart implants, hearing aids, timepieces).
Safe operation
Use magnets consciously. Their powerful strength can shock even professionals. Be vigilant and respect their force.
Pinching danger
Risk of injury: The attraction force is so great that it can result in hematomas, pinching, and broken bones. Protective gloves are recommended.
Magnet fragility
Neodymium magnets are ceramic materials, which means they are fragile like glass. Collision of two magnets will cause them shattering into shards.
Combustion hazard
Powder generated during cutting of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.
