Strengths and weaknesses of neodymium magnets.
Pros
- They have stable power, and over nearly 10 years their performance decreases symbolically – ~1% (according to theory),
- Magnets perfectly protect themselves against loss of magnetization caused by external fields,
- By using a lustrous layer of gold, the element presents an professional look,
- They are known for high magnetic induction at the operating surface, which increases their power,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for operation at temperatures approaching 230°C and above...
- Thanks to the option of precise molding and adaptation to individualized requirements, magnetic components can be modeled in a broad palette of forms and dimensions, which makes them more universal,
- Versatile presence in modern industrial fields – they are utilized in mass storage devices, electromotive mechanisms, diagnostic systems, and multitasking production systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a steel housing, which not only secures them against impacts but also raises their durability
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (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
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in creating threads and complex shapes in magnets, we recommend using cover - magnetic mount.
- Health risk resulting from small fragments of magnets pose a threat, if swallowed, which is particularly important in the context of child safety. Additionally, tiny parts of these magnets are able to complicate diagnosis medical after entering the body.
- With large orders the cost of neodymium magnets can be a barrier,
Holding force characteristics
Best holding force of the magnet in ideal parameters – what contributes to it?
- on a block made of mild steel, perfectly concentrating the magnetic field
- with a cross-section minimum 10 mm
- with an ideally smooth contact surface
- without any insulating layer between the magnet and steel
- during pulling in a direction vertical to the mounting surface
- at room temperature
What influences lifting capacity in practice
- Gap (between the magnet and the plate), since even a microscopic distance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to paint, rust or debris).
- Load vector – highest force is reached only during perpendicular pulling. The resistance to sliding of the magnet along the surface is standardly several times smaller (approx. 1/5 of the lifting capacity).
- Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Chemical composition of the base – low-carbon steel gives the best results. Alloy admixtures reduce magnetic permeability and holding force.
- Plate texture – ground elements guarantee perfect abutment, which improves field saturation. Uneven metal weaken the grip.
- Heat – NdFeB sinters have a negative temperature coefficient. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).
Lifting capacity testing was conducted on a smooth plate of optimal thickness, under a perpendicular pulling force, however under attempts to slide the magnet the holding force is lower. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the load capacity.
H&S for magnets
Do not underestimate power
Handle with care. Rare earth magnets act from a distance and connect with massive power, often faster than you can react.
Nickel coating and allergies
Studies show that the nickel plating (the usual finish) is a strong allergen. If you have an allergy, refrain from direct skin contact and choose encased magnets.
Danger to the youngest
Always keep magnets out of reach of children. Choking hazard is high, and the effects of magnets clamping inside the body are very dangerous.
Beware of splinters
Watch out for shards. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. Eye protection is mandatory.
Keep away from electronics
A powerful magnetic field interferes with the operation of magnetometers in smartphones and navigation systems. Do not bring magnets near a device to avoid damaging the sensors.
Fire risk
Powder produced during machining of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.
Bodily injuries
Big blocks can break fingers in a fraction of a second. Under no circumstances place your hand between two strong magnets.
Do not overheat magnets
Regular neodymium magnets (grade N) lose power when the temperature goes above 80°C. The loss of strength is permanent.
Keep away from computers
Very strong magnetic fields can erase data on credit cards, HDDs, and storage devices. Maintain a gap of at least 10 cm.
ICD Warning
For implant holders: Strong magnetic fields disrupt electronics. Maintain minimum 30 cm distance or request help to handle the magnets.
