Strengths and weaknesses of neodymium magnets.
Pros
- They retain full power for around 10 years – the drop is just ~1% (in theory),
- They do not lose their magnetic properties even under external field action,
- By applying a lustrous layer of nickel, the element acquires an modern look,
- Magnets are characterized by maximum magnetic induction on the active area,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to the possibility of flexible shaping and adaptation to unique needs, neodymium magnets can be manufactured in a wide range of geometric configurations, which makes them more universal,
- Significant place in advanced technology sectors – they are commonly used in data components, brushless drives, diagnostic systems, also industrial machines.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Disadvantages
- They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
- NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (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
- They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in creating nuts and complex shapes in magnets, we recommend using cover - magnetic mechanism.
- Possible danger to health – tiny shards of magnets are risky, if swallowed, which is particularly important in the context of child safety. It is also worth noting that small elements of these devices can complicate diagnosis medical after entering the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Highest magnetic holding force – what it depends on?
- on a plate made of mild steel, effectively closing the magnetic field
- whose thickness equals approx. 10 mm
- with an ground contact surface
- under conditions of gap-free contact (surface-to-surface)
- under perpendicular application of breakaway force (90-degree angle)
- at room temperature
What influences lifting capacity in practice
- Distance – existence of any layer (rust, dirt, gap) interrupts the magnetic circuit, which lowers power rapidly (even by 50% at 0.5 mm).
- Angle of force application – maximum parameter is reached only during pulling at a 90° angle. The shear force of the magnet along the plate is standardly many times lower (approx. 1/5 of the lifting capacity).
- Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
- Material composition – different alloys reacts the same. High carbon content worsen the interaction with the magnet.
- Smoothness – full contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Thermal environment – temperature increase causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, however under parallel forces the holding force is lower. Additionally, even a slight gap between the magnet and the plate lowers the load capacity.
Precautions when working with neodymium magnets
Avoid contact if allergic
Studies show that nickel (the usual finish) is a strong allergen. If you have an allergy, refrain from touching magnets with bare hands and opt for encased magnets.
Impact on smartphones
An intense magnetic field negatively affects the functioning of magnetometers in phones and GPS navigation. Do not bring magnets near a smartphone to avoid damaging the sensors.
Combustion hazard
Mechanical processing of NdFeB material carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Magnet fragility
Protect your eyes. Magnets can fracture upon uncontrolled impact, launching shards into the air. Eye protection is mandatory.
Product not for children
Strictly store magnets away from children. Ingestion danger is significant, and the consequences of magnets clamping inside the body are life-threatening.
Threat to electronics
Data protection: Neodymium magnets can damage data carriers and delicate electronics (pacemakers, hearing aids, mechanical watches).
Operating temperature
Standard neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. The loss of strength is permanent.
Bodily injuries
Pinching hazard: The attraction force is so great that it can cause hematomas, pinching, and even bone fractures. Protective gloves are recommended.
Life threat
For implant holders: Strong magnetic fields affect electronics. Keep at least 30 cm distance or ask another person to handle the magnets.
Do not underestimate power
Handle magnets consciously. Their powerful strength can shock even experienced users. Stay alert and respect their power.
