Strengths as well as weaknesses of rare earth magnets.
Strengths
- They retain full power for almost 10 years – the drop is just ~1% (in theory),
- They retain their magnetic properties even under external field action,
- The use of an aesthetic finish of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- Neodymium magnets generate maximum magnetic induction on a their surface, which ensures high operational effectiveness,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
- Thanks to modularity in forming and the ability to customize to individual projects,
- Wide application in modern technologies – they serve a role in HDD drives, drive modules, diagnostic systems, and industrial machines.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also improves its resistance to damage
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation as well as corrosion.
- Limited possibility of making threads in the magnet and complicated forms - preferred is a housing - magnetic holder.
- Potential hazard resulting from small fragments of magnets are risky, if swallowed, which gains importance in the context of child safety. It is also worth noting that small components of these products are able to be problematic in diagnostics medical in case of swallowing.
- With budget limitations the cost of neodymium magnets is a challenge,
Pull force analysis
Highest magnetic holding force – what affects it?
- with the application of a yoke made of low-carbon steel, ensuring full magnetic saturation
- whose thickness equals approx. 10 mm
- with an polished touching surface
- without any clearance between the magnet and steel
- under axial application of breakaway force (90-degree angle)
- at temperature approx. 20 degrees Celsius
Lifting capacity in practice – influencing factors
- Gap between surfaces – even a fraction of a millimeter of separation (caused e.g. by veneer or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
- Load vector – highest force is available only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is usually several times smaller (approx. 1/5 of the lifting capacity).
- Base massiveness – insufficiently thick sheet causes magnetic saturation, causing part of the power to be lost into the air.
- Material composition – different alloys reacts the same. Alloy additives worsen the attraction effect.
- Plate texture – ground elements ensure maximum contact, which improves force. Rough surfaces weaken the grip.
- Thermal environment – heating the magnet causes a temporary drop of force. Check the maximum operating temperature for a given model.
Lifting capacity was assessed using a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular pulling force, in contrast under attempts to slide the magnet the holding force is lower. Additionally, even a minimal clearance between the magnet and the plate reduces the load capacity.
Safe handling of NdFeB magnets
Finger safety
Large magnets can smash fingers instantly. Under no circumstances put your hand betwixt two strong magnets.
Combustion hazard
Mechanical processing of NdFeB material carries a risk of fire hazard. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Magnetic media
Powerful magnetic fields can erase data on credit cards, hard drives, and storage devices. Stay away of min. 10 cm.
Safe operation
Handle magnets consciously. Their immense force can shock even professionals. Stay alert and respect their power.
Magnetic interference
A strong magnetic field disrupts the operation of magnetometers in phones and navigation systems. Maintain magnets near a smartphone to avoid breaking the sensors.
Magnet fragility
NdFeB magnets are ceramic materials, which means they are very brittle. Collision of two magnets leads to them breaking into shards.
Heat warning
Standard neodymium magnets (grade N) lose power when the temperature surpasses 80°C. This process is irreversible.
Swallowing risk
These products are not toys. Eating several magnets may result in them attracting across intestines, which constitutes a critical condition and necessitates urgent medical intervention.
Nickel coating and allergies
Studies show that the nickel plating (standard magnet coating) is a potent allergen. If your skin reacts to metals, refrain from touching magnets with bare hands and opt for versions in plastic housing.
Health Danger
For implant holders: Powerful magnets disrupt medical devices. Keep at least 30 cm distance or request help to work with the magnets.
