Pros and cons of neodymium magnets.
Benefits
- They do not lose magnetism, even during around ten years – the drop in power is only ~1% (theoretically),
- They retain their magnetic properties even under close interference source,
- By applying a shiny layer of nickel, the element presents an nice look,
- They show high magnetic induction at the operating surface, which improves attraction properties,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Possibility of exact shaping and adapting to individual conditions,
- Key role in electronics industry – they are utilized in magnetic memories, electromotive mechanisms, advanced medical instruments, as well as modern systems.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Cons
- At strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- We warn that neodymium magnets can reduce their strength 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 magnets in rubber or plastics, which secure oxidation as well as corrosion.
- We suggest a housing - magnetic mechanism, due to difficulties in realizing threads inside the magnet and complicated forms.
- Possible danger related to microscopic parts of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child safety. It is also worth noting that small elements of these products can complicate diagnosis medical in case of swallowing.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities
Lifting parameters
Best holding force of the magnet in ideal parameters – what it depends on?
- with the contact of a yoke made of special test steel, ensuring full magnetic saturation
- possessing a thickness of min. 10 mm to avoid saturation
- with a plane cleaned and smooth
- with zero gap (no coatings)
- for force applied at a right angle (in the magnet axis)
- at ambient temperature approx. 20 degrees Celsius
Determinants of practical lifting force of a magnet
- Space between magnet and steel – every millimeter of separation (caused e.g. by veneer or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
- Load vector – highest force is reached only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is standardly many times lower (approx. 1/5 of the lifting capacity).
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
- Steel grade – the best choice is pure iron steel. Cast iron may have worse magnetic properties.
- Surface quality – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
- Thermal conditions – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity was assessed by applying a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, however under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Additionally, even a small distance between the magnet’s surface and the plate lowers the holding force.
Warnings
Eye protection
Despite the nickel coating, the material is delicate and not impact-resistant. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
GPS and phone interference
A powerful magnetic field disrupts the functioning of compasses in smartphones and GPS navigation. Maintain magnets close to a smartphone to prevent breaking the sensors.
Heat warning
Control the heat. Heating the magnet to high heat will permanently weaken its magnetic structure and strength.
Do not underestimate power
Exercise caution. Neodymium magnets attract from a long distance and connect with massive power, often faster than you can move away.
Crushing risk
Large magnets can smash fingers in a fraction of a second. Under no circumstances place your hand betwixt two strong magnets.
Fire warning
Machining of NdFeB material carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Health Danger
Health Alert: Neodymium magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.
Metal Allergy
Studies show that nickel (the usual finish) is a strong allergen. For allergy sufferers, avoid direct skin contact or opt for coated magnets.
Threat to electronics
Intense magnetic fields can erase data on credit cards, HDDs, and storage devices. Keep a distance of min. 10 cm.
No play value
NdFeB magnets are not toys. Swallowing multiple magnets may result in them pinching intestinal walls, which poses a direct threat to life and necessitates urgent medical intervention.
