Advantages as well as disadvantages of neodymium magnets.
Advantages
- They retain attractive force for around 10 years – the drop is just ~1% (according to analyses),
- Neodymium magnets are distinguished by highly resistant to demagnetization caused by external field sources,
- A magnet with a metallic gold surface has better aesthetics,
- They are known for high magnetic induction at the operating surface, which increases their power,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
- Possibility of custom forming as well as modifying to specific needs,
- Versatile presence in innovative solutions – they find application in HDD drives, drive modules, diagnostic systems, as well as industrial machines.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Cons
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
- Neodymium magnets lose their power 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
- They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- We suggest a housing - magnetic mount, due to difficulties in realizing threads inside the magnet and complicated shapes.
- Potential hazard to health – tiny shards of magnets pose a threat, in case of ingestion, which becomes key in the context of child safety. Additionally, small components of these devices are able to disrupt the diagnostic process medical in case of swallowing.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities
Lifting parameters
Best holding force of the magnet in ideal parameters – what contributes to it?
- using a sheet made of high-permeability steel, functioning as a ideal flux conductor
- possessing a massiveness of at least 10 mm to ensure full flux closure
- with an ideally smooth contact surface
- with zero gap (no impurities)
- during pulling in a direction vertical to the plane
- at ambient temperature room level
Determinants of lifting force in real conditions
- Air gap (betwixt the magnet and the metal), as even a microscopic distance (e.g. 0.5 mm) can cause a drastic drop in lifting capacity by up to 50% (this also applies to varnish, corrosion or dirt).
- Angle of force application – maximum parameter is obtained only during pulling at a 90° angle. The shear force of the magnet along the plate is typically many times lower (approx. 1/5 of the lifting capacity).
- Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Metal type – not every steel reacts the same. High carbon content worsen the interaction with the magnet.
- Surface finish – full contact is obtained only on smooth steel. Rough texture reduce the real contact area, reducing force.
- Thermal environment – temperature increase causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.
Lifting capacity was determined using a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular detachment force, however under parallel forces the holding force is lower. Additionally, even a minimal clearance between the magnet and the plate lowers the lifting capacity.
Magnetic media
Very strong magnetic fields can corrupt files on credit cards, HDDs, and storage devices. Maintain a gap of min. 10 cm.
Machining danger
Powder produced during grinding of magnets is self-igniting. Do not drill into magnets unless you are an expert.
Heat warning
Do not overheat. NdFeB magnets are sensitive to heat. If you require resistance above 80°C, look for HT versions (H, SH, UH).
Health Danger
Warning for patients: Strong magnetic fields affect medical devices. Keep at least 30 cm distance or ask another person to work with the magnets.
This is not a toy
Only for adults. Small elements can be swallowed, leading to serious injuries. Keep out of reach of children and animals.
Impact on smartphones
A powerful magnetic field disrupts the operation of magnetometers in phones and GPS navigation. Keep magnets close to a device to prevent damaging the sensors.
Conscious usage
Handle magnets consciously. Their immense force can shock even experienced users. Stay alert and respect their power.
Serious injuries
Big blocks can crush fingers in a fraction of a second. Do not put your hand betwixt two attracting surfaces.
Magnets are brittle
Protect your eyes. Magnets can explode upon violent connection, ejecting shards into the air. We recommend safety glasses.
Metal Allergy
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If skin irritation appears, immediately stop handling magnets and use protective gear.
