Strengths as well as weaknesses of neodymium magnets.
Strengths
- They have constant strength, and over nearly 10 years their attraction force decreases symbolically – ~1% (in testing),
- They possess excellent resistance to weakening of magnetic properties due to external fields,
- In other words, due to the smooth surface of silver, the element gains visual value,
- They feature high magnetic induction at the operating surface, which increases their power,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to flexibility in constructing and the capacity to adapt to complex applications,
- Significant place in electronics industry – they are commonly used in computer drives, electric motors, precision medical tools, and complex engineering applications.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a strong case, which not only secures them against impacts but also increases their durability
- When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- They oxidize in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- We recommend a housing - magnetic holder, due to difficulties in creating threads inside the magnet and complex shapes.
- Health risk resulting from small fragments of magnets are risky, in case of ingestion, which gains importance in the aspect of protecting the youngest. Additionally, tiny parts of these products 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
Holding force characteristics
Maximum magnetic pulling force – what contributes to it?
- with the application of a sheet made of low-carbon steel, ensuring maximum field concentration
- possessing a massiveness of minimum 10 mm to ensure full flux closure
- with a plane free of scratches
- under conditions of ideal adhesion (metal-to-metal)
- during detachment in a direction perpendicular to the plane
- at ambient temperature approx. 20 degrees Celsius
Magnet lifting force in use – key factors
- Distance (betwixt the magnet and the plate), as even a tiny clearance (e.g. 0.5 mm) can cause a decrease in force by up to 50% (this also applies to paint, corrosion or dirt).
- Loading method – declared lifting capacity refers to detachment vertically. When slipping, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Metal type – not every steel reacts the same. High carbon content worsen the interaction with the magnet.
- Surface quality – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
- Heat – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity was assessed using a polished steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, however under attempts to slide the magnet the holding force is lower. In addition, even a minimal clearance between the magnet and the plate reduces the load capacity.
Safety rules for work with neodymium magnets
Safe distance
Very strong magnetic fields can corrupt files on payment cards, HDDs, and storage devices. Keep a distance of at least 10 cm.
Shattering risk
NdFeB magnets are sintered ceramics, meaning they are prone to chipping. Collision of two magnets will cause them shattering into small pieces.
Swallowing risk
These products are not suitable for play. Eating a few magnets can lead to them pinching intestinal walls, which poses a severe health hazard and requires immediate surgery.
GPS Danger
Navigation devices and mobile phones are highly susceptible to magnetic fields. Close proximity with a strong magnet can decalibrate the sensors in your phone.
Dust is flammable
Fire hazard: Rare earth powder is explosive. Avoid machining magnets in home conditions as this risks ignition.
Thermal limits
Avoid heat. NdFeB magnets are susceptible to temperature. If you require operation above 80°C, look for special high-temperature series (H, SH, UH).
ICD Warning
Health Alert: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.
Crushing risk
Protect your hands. Two large magnets will join immediately with a force of several hundred kilograms, destroying anything in their path. Exercise extreme caution!
Conscious usage
Use magnets with awareness. Their immense force can shock even professionals. Plan your moves and do not underestimate their force.
Nickel coating and allergies
A percentage of the population suffer from a sensitization to Ni, which is the standard coating for NdFeB magnets. Frequent touching can result in dermatitis. We strongly advise wear safety gloves.
