Advantages and disadvantages of rare earth magnets.
Advantages
- They retain full power for nearly 10 years – the drop is just ~1% (in theory),
- Neodymium magnets are distinguished by exceptionally resistant to magnetic field loss caused by external field sources,
- By using a lustrous layer of silver, the element acquires an modern look,
- Neodymium magnets ensure maximum magnetic induction on a contact point, which allows for strong attraction,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
- Possibility of detailed creating and optimizing to defined requirements,
- Universal use in innovative solutions – they are commonly used in hard drives, electric motors, advanced medical instruments, also technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which makes them useful in compact constructions
Limitations
- They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
- Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in realizing threads and complicated forms in magnets, we propose using cover - magnetic holder.
- Health risk resulting from small fragments of magnets can be dangerous, in case of ingestion, which gains importance in the context of child safety. Additionally, tiny parts of these magnets are able to 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
Holding force characteristics
Maximum lifting capacity of the magnet – what affects it?
- with the application of a sheet made of low-carbon steel, ensuring maximum field concentration
- possessing a thickness of min. 10 mm to avoid saturation
- characterized by smoothness
- with direct contact (without coatings)
- under perpendicular application of breakaway force (90-degree angle)
- in temp. approx. 20°C
Impact of factors on magnetic holding capacity in practice
- Gap between surfaces – even a fraction of a 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 – maximum parameter is reached only during pulling at a 90° angle. The force required to slide of the magnet along the plate is usually several times smaller (approx. 1/5 of the lifting capacity).
- Substrate thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Plate material – mild steel attracts best. Higher carbon content reduce magnetic permeability and lifting capacity.
- Base smoothness – the smoother and more polished the surface, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
- Thermal conditions – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity testing was carried out on a smooth plate of optimal thickness, under a perpendicular pulling force, whereas under parallel forces the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate decreases the holding force.
Warnings
Combustion hazard
Dust produced during grinding of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
Magnetic media
Device Safety: Strong magnets can damage payment cards and delicate electronics (pacemakers, hearing aids, timepieces).
Conscious usage
Before starting, read the rules. Sudden snapping can break the magnet or hurt your hand. Be predictive.
Phone sensors
GPS units and mobile phones are extremely susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can ruin the sensors in your phone.
Material brittleness
Despite metallic appearance, the material is delicate and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
Allergic reactions
Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If skin irritation occurs, immediately stop working with magnets and use protective gear.
Operating temperature
Standard neodymium magnets (grade N) undergo demagnetization when the temperature goes above 80°C. Damage is permanent.
Health Danger
For implant holders: Powerful magnets disrupt electronics. Maintain at least 30 cm distance or request help to handle the magnets.
Swallowing risk
These products are not intended for children. Accidental ingestion of several magnets can lead to them attracting across intestines, which poses a direct threat to life and requires immediate surgery.
Physical harm
Risk of injury: The attraction force is so great that it can result in blood blisters, crushing, and broken bones. Use thick gloves.
