Advantages and disadvantages of neodymium magnets.
Benefits
- Their power is durable, and after around 10 years it decreases only by ~1% (theoretically),
- They are resistant to demagnetization induced by presence of other magnetic fields,
- In other words, due to the aesthetic finish of silver, the element becomes visually attractive,
- Magnetic induction on the top side of the magnet is very high,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- Possibility of precise modeling and adjusting to complex requirements,
- Universal use in modern technologies – they are used in mass storage devices, drive modules, advanced medical instruments, and industrial machines.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Weaknesses
- 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
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in realizing threads and complicated forms in magnets, we propose using a housing - magnetic holder.
- Possible danger to health – tiny shards of magnets are risky, in case of ingestion, which is particularly important in the context of child safety. Furthermore, small elements of these devices are able to be problematic in diagnostics medical in case of swallowing.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities
Pull force analysis
Maximum lifting capacity of the magnet – what contributes to it?
- using a sheet made of low-carbon steel, acting as a magnetic yoke
- possessing a thickness of at least 10 mm to ensure full flux closure
- characterized by even structure
- without any clearance between the magnet and steel
- during detachment in a direction vertical to the plane
- in neutral thermal conditions
Lifting capacity in real conditions – factors
- Distance – the presence of foreign body (rust, tape, gap) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of generating force.
- Steel grade – the best choice is pure iron steel. Stainless steels may generate lower lifting capacity.
- Smoothness – ideal contact is obtained only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
- Thermal conditions – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).
Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under parallel forces the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate reduces the holding force.
Safe handling of neodymium magnets
Safe distance
Data protection: Strong magnets can ruin data carriers and sensitive devices (pacemakers, hearing aids, mechanical watches).
Compass and GPS
Navigation devices and mobile phones are highly sensitive to magnetic fields. Direct contact with a strong magnet can permanently damage the internal compass in your phone.
Safe operation
Use magnets consciously. Their powerful strength can surprise even experienced users. Stay alert and do not underestimate their force.
Fire risk
Powder generated during cutting of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.
Crushing force
Watch your fingers. Two powerful magnets will snap together instantly with a force of several hundred kilograms, destroying everything in their path. Be careful!
Risk of cracking
Beware of splinters. Magnets can fracture upon uncontrolled impact, launching shards into the air. Eye protection is mandatory.
Warning for heart patients
Health Alert: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.
This is not a toy
Absolutely store magnets out of reach of children. Risk of swallowing is high, and the effects of magnets connecting inside the body are life-threatening.
Maximum temperature
Regular neodymium magnets (grade N) lose power when the temperature surpasses 80°C. The loss of strength is permanent.
Warning for allergy sufferers
Certain individuals have a contact allergy to Ni, which is the standard coating for neodymium magnets. Extended handling may cause skin redness. We recommend use safety gloves.
