Strengths and weaknesses of rare earth magnets.
Strengths
- They retain magnetic properties for almost ten years – the drop is just ~1% (based on simulations),
- Neodymium magnets are distinguished by extremely resistant to demagnetization caused by magnetic disturbances,
- A magnet with a metallic silver surface has better aesthetics,
- Magnets have huge magnetic induction on the outer side,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Due to the ability of accurate shaping and adaptation to specialized requirements, magnetic components can be modeled in a wide range of forms and dimensions, which amplifies use scope,
- Universal use in advanced technology sectors – they are utilized in computer drives, electric drive systems, medical devices, also multitasking production systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Limitations
- They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- Due to limitations in producing nuts and complex shapes in magnets, we recommend using casing - magnetic holder.
- Possible danger related to microscopic parts of magnets pose a threat, if swallowed, which becomes key in the aspect of protecting the youngest. Additionally, small components of these devices can be problematic in diagnostics medical when they are in the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities
Holding force characteristics
Maximum lifting force for a neodymium magnet – what contributes to it?
- with the contact of a sheet made of special test steel, guaranteeing full magnetic saturation
- with a thickness of at least 10 mm
- with an ideally smooth contact surface
- with total lack of distance (without paint)
- under axial force vector (90-degree angle)
- at temperature approx. 20 degrees Celsius
Practical aspects of lifting capacity – factors
- Gap (between the magnet and the metal), since even a very small distance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
- Force direction – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet exhibits much less (often approx. 20-30% of maximum force).
- Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Plate material – mild steel attracts best. Higher carbon content decrease magnetic properties and holding force.
- Surface quality – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
- Temperature influence – high temperature weakens magnetic field. Too high temperature can permanently damage the magnet.
Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under shearing force the load capacity is reduced by as much as 5 times. Additionally, even a slight gap between the magnet and the plate reduces the load capacity.
Safety rules for work with NdFeB magnets
Magnetic media
Very strong magnetic fields can corrupt files on credit cards, HDDs, and other magnetic media. Keep a distance of at least 10 cm.
Flammability
Powder produced during grinding of magnets is combustible. Avoid drilling into magnets unless you are an expert.
Choking Hazard
Always store magnets away from children. Choking hazard is high, and the consequences of magnets connecting inside the body are fatal.
Handling rules
Before use, check safety instructions. Sudden snapping can break the magnet or hurt your hand. Be predictive.
Nickel allergy
It is widely known that nickel (the usual finish) is a potent allergen. For allergy sufferers, prevent touching magnets with bare hands and choose coated magnets.
ICD Warning
Warning for patients: Powerful magnets disrupt electronics. Maintain minimum 30 cm distance or request help to handle the magnets.
Maximum temperature
Standard neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. Damage is permanent.
Bone fractures
Large magnets can smash fingers in a fraction of a second. Under no circumstances put your hand between two strong magnets.
GPS Danger
Navigation devices and smartphones are extremely sensitive to magnetism. Direct contact with a powerful NdFeB magnet can decalibrate the sensors in your phone.
Material brittleness
Despite the nickel coating, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.
