Pros and cons of neodymium magnets.
Advantages
- They retain full power for almost ten years – the loss is just ~1% (according to analyses),
- They are extremely resistant to demagnetization induced by external magnetic fields,
- By covering with a shiny coating of silver, the element gains an professional look,
- Magnets possess huge magnetic induction on the outer side,
- Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to the possibility of accurate molding and customization to individualized projects, NdFeB magnets can be manufactured in a variety of geometric configurations, which increases their versatility,
- Versatile presence in high-tech industry – they find application in magnetic memories, motor assemblies, advanced medical instruments, also other advanced devices.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a strong case, which not only secures them against impacts but also raises their 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 stability even at temperatures up to 230°C
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
- Due to limitations in producing threads and complicated shapes in magnets, we recommend using casing - magnetic mechanism.
- Potential hazard resulting from small fragments of magnets pose a threat, in case of ingestion, which becomes key in the context of child safety. It is also worth noting that small elements of these products are able to complicate diagnosis medical when they are in the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Maximum lifting force for a neodymium magnet – what it depends on?
- on a plate made of mild steel, perfectly concentrating the magnetic field
- whose transverse dimension is min. 10 mm
- with an polished touching surface
- without the slightest clearance between the magnet and steel
- for force acting at a right angle (pull-off, not shear)
- in stable room temperature
Practical lifting capacity: influencing factors
- Distance – the presence of foreign body (paint, dirt, gap) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Direction of force – maximum parameter is obtained only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is usually many times smaller (approx. 1/5 of the lifting capacity).
- Substrate thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Chemical composition of the base – low-carbon steel gives the best results. Alloy steels reduce magnetic permeability and lifting capacity.
- Surface quality – the smoother and more polished the plate, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
- Thermal conditions – neodymium magnets have a sensitivity to temperature. When it is hot they are weaker, and in frost gain strength (up to a certain limit).
Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the holding force is lower. In addition, even a small distance between the magnet’s surface and the plate reduces the load capacity.
Precautions when working with neodymium magnets
Do not underestimate power
Exercise caution. Neodymium magnets act from a distance and snap with massive power, often quicker than you can move away.
Serious injuries
Danger of trauma: The pulling power is so great that it can cause blood blisters, crushing, and even bone fractures. Use thick gloves.
Dust explosion hazard
Mechanical processing of NdFeB material carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
ICD Warning
Warning for patients: Strong magnetic fields disrupt electronics. Maintain at least 30 cm distance or request help to work with the magnets.
Thermal limits
Standard neodymium magnets (grade N) lose power when the temperature goes above 80°C. The loss of strength is permanent.
Nickel coating and allergies
Studies show that the nickel plating (the usual finish) is a potent allergen. If your skin reacts to metals, avoid direct skin contact or opt for encased magnets.
Phone sensors
Note: rare earth magnets produce a field that disrupts precision electronics. Maintain a separation from your phone, device, and navigation systems.
Protect data
Device Safety: Strong magnets can ruin data carriers and delicate electronics (heart implants, medical aids, mechanical watches).
No play value
Only for adults. Small elements can be swallowed, causing severe trauma. Store away from children and animals.
Risk of cracking
Protect your eyes. Magnets can explode upon violent connection, ejecting shards into the air. Wear goggles.
