Strengths as well as weaknesses of neodymium magnets.
Pros
- Their magnetic field is durable, and after approximately 10 years it decreases only by ~1% (theoretically),
- They feature excellent resistance to magnetic field loss due to external fields,
- In other words, due to the aesthetic layer of nickel, the element is aesthetically pleasing,
- Magnetic induction on the surface of the magnet remains exceptional,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Possibility of accurate modeling as well as adjusting to precise conditions,
- Fundamental importance in innovative solutions – they are commonly used in hard drives, brushless drives, medical devices, and complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which makes them useful in miniature devices
Weaknesses
- At very strong impacts they can break, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Limited ability of creating threads in the magnet and complex forms - preferred is casing - mounting mechanism.
- Possible danger related to microscopic parts of magnets pose a threat, in case of ingestion, which is particularly important in the context of child safety. It is also worth noting that tiny parts of these devices are able to be problematic in diagnostics medical after entering the body.
- Due to complex production process, their price is relatively high,
Lifting parameters
Magnetic strength at its maximum – what it depends on?
- using a sheet made of low-carbon steel, serving as a circuit closing element
- whose thickness is min. 10 mm
- with a plane cleaned and smooth
- without any air gap between the magnet and steel
- during pulling in a direction perpendicular to the plane
- in neutral thermal conditions
Practical aspects of lifting capacity – factors
- Distance – the presence of any layer (rust, tape, gap) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
- Loading method – catalog parameter refers to pulling vertically. When applying parallel force, the magnet exhibits much less (typically approx. 20-30% of maximum force).
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
- Metal type – different alloys reacts the same. Alloy additives worsen the interaction with the magnet.
- Base smoothness – the smoother and more polished the surface, the better the adhesion and stronger the hold. Roughness acts like micro-gaps.
- Thermal conditions – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).
Lifting capacity was determined by applying a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, whereas under shearing force the load capacity is reduced by as much as fivefold. Moreover, even a minimal clearance between the magnet and the plate reduces the holding force.
H&S for magnets
Risk of cracking
Watch out for shards. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. We recommend safety glasses.
Pinching danger
Risk of injury: The pulling power is so immense that it can result in blood blisters, crushing, and broken bones. Protective gloves are recommended.
Allergy Warning
Allergy Notice: The nickel-copper-nickel coating contains nickel. If skin irritation happens, immediately stop working with magnets and wear gloves.
Life threat
Warning for patients: Strong magnetic fields disrupt electronics. Keep minimum 30 cm distance or ask another person to handle the magnets.
Handling rules
Before use, read the rules. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.
Keep away from computers
Avoid bringing magnets close to a purse, laptop, or screen. The magnetism can destroy these devices and erase data from cards.
Fire risk
Dust generated during cutting of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
Compass and GPS
Remember: rare earth magnets produce a field that disrupts precision electronics. Keep a separation from your mobile, tablet, and GPS.
Demagnetization risk
Avoid heat. Neodymium magnets are sensitive to heat. If you require operation above 80°C, inquire about special high-temperature series (H, SH, UH).
Product not for children
Product intended for adults. Small elements can be swallowed, causing serious injuries. Store away from kids and pets.
