Strengths as well as weaknesses of neodymium magnets.
Strengths
- They have stable power, and over around 10 years their attraction force decreases symbolically – ~1% (according to theory),
- They feature excellent resistance to magnetic field loss as a result of opposing magnetic fields,
- By covering with a shiny coating of gold, the element has an aesthetic look,
- Magnetic induction on the surface of the magnet is maximum,
- 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 flexibility in constructing and the capacity to modify to specific needs,
- Significant place in modern industrial fields – they are utilized in mass storage devices, electric motors, advanced medical instruments, also multitasking production systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Weaknesses
- They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
- 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
- We recommend cover - magnetic mount, due to difficulties in realizing threads inside the magnet and complex shapes.
- Potential hazard to health – tiny shards of magnets can be dangerous, if swallowed, which is particularly important in the context of child health protection. Additionally, small elements of these magnets can complicate diagnosis medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Optimal lifting capacity of a neodymium magnet – what affects it?
- with the application of a sheet made of special test steel, ensuring full magnetic saturation
- with a thickness no less than 10 mm
- with a plane perfectly flat
- under conditions of no distance (metal-to-metal)
- during detachment in a direction perpendicular to the plane
- at room temperature
Lifting capacity in practice – influencing factors
- Gap between surfaces – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Load vector – maximum parameter 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).
- Steel thickness – insufficiently thick plate causes magnetic saturation, causing part of the power to be lost to the other side.
- Plate material – low-carbon steel attracts best. Alloy steels reduce magnetic permeability and holding force.
- Surface structure – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Roughness acts like micro-gaps.
- Thermal conditions – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).
Lifting capacity was measured with the use of a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, in contrast under attempts to slide the magnet the holding force is lower. In addition, even a slight gap between the magnet and the plate lowers the load capacity.
Safe handling of NdFeB magnets
Thermal limits
Watch the temperature. Exposing the magnet above 80 degrees Celsius will destroy its magnetic structure and strength.
Warning for heart patients
Medical warning: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have medical devices.
Crushing risk
Pinching hazard: The attraction force is so great that it can result in hematomas, crushing, and even bone fractures. Protective gloves are recommended.
Fire warning
Drilling and cutting of NdFeB material poses a fire risk. Magnetic powder reacts violently with oxygen and is hard to extinguish.
Caution required
Be careful. Rare earth magnets attract from a long distance and snap with huge force, often quicker than you can react.
Choking Hazard
Only for adults. Small elements can be swallowed, leading to intestinal necrosis. Store away from children and animals.
Allergic reactions
Studies show that nickel (standard magnet coating) is a common allergen. If you have an allergy, refrain from touching magnets with bare hands or select coated magnets.
Keep away from computers
Powerful magnetic fields can erase data on payment cards, HDDs, and other magnetic media. Keep a distance of at least 10 cm.
Eye protection
Neodymium magnets are sintered ceramics, meaning they are fragile like glass. Clashing of two magnets leads to them breaking into small pieces.
GPS Danger
Note: neodymium magnets generate a field that interferes with precision electronics. Keep a separation from your mobile, tablet, and navigation systems.
