Strengths and weaknesses of rare earth magnets.
Strengths
- Their magnetic field is durable, and after approximately ten years it decreases only by ~1% (according to research),
- Neodymium magnets are characterized by remarkably resistant to demagnetization caused by external magnetic fields,
- In other words, due to the metallic layer of silver, the element becomes visually attractive,
- They are known for high magnetic induction at the operating surface, which increases their power,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Thanks to the option of precise shaping and adaptation to custom needs, NdFeB magnets can be modeled in a wide range of forms and dimensions, which amplifies use scope,
- Fundamental importance in electronics industry – they are utilized in HDD drives, drive modules, medical devices, and modern systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Cons
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a special holder, which not only protects them against impacts but also increases their durability
- 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 as well as 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
- They rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Limited ability of making nuts in the magnet and complex forms - preferred is a housing - mounting mechanism.
- Health risk related to microscopic parts of magnets pose a threat, in case of ingestion, which is particularly important in the context of child health protection. Additionally, small elements of these devices are able to complicate diagnosis medical when they are in the body.
- Due to neodymium price, their price is higher than average,
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what affects it?
- on a block made of structural steel, optimally conducting the magnetic flux
- whose thickness reaches at least 10 mm
- with a plane cleaned and smooth
- without any air gap between the magnet and steel
- for force acting at a right angle (pull-off, not shear)
- in temp. approx. 20°C
Magnet lifting force in use – key factors
- Space between surfaces – every millimeter of distance (caused e.g. by veneer or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Angle of force application – highest force is obtained only during perpendicular pulling. The shear force of the magnet along the surface is typically several times smaller (approx. 1/5 of the lifting capacity).
- 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.
- Material type – the best choice is pure iron steel. Hardened steels may have worse magnetic properties.
- Surface structure – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
- Thermal factor – hot environment weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under perpendicular forces, however under attempts to slide the magnet the lifting capacity is smaller. In addition, even a slight gap between the magnet’s surface and the plate reduces the load capacity.
H&S for magnets
ICD Warning
For implant holders: Powerful magnets affect electronics. Maintain at least 30 cm distance or request help to work with the magnets.
Dust is flammable
Dust produced during machining of magnets is combustible. Do not drill into magnets unless you are an expert.
Powerful field
Handle magnets consciously. Their immense force can surprise even professionals. Stay alert and respect their power.
Do not give to children
Strictly store magnets out of reach of children. Ingestion danger is high, and the effects of magnets clamping inside the body are fatal.
Nickel coating and allergies
Allergy Notice: The nickel-copper-nickel coating contains nickel. If an allergic reaction appears, cease working with magnets and wear gloves.
Do not overheat magnets
Keep cool. Neodymium magnets are susceptible to heat. If you require operation above 80°C, inquire about HT versions (H, SH, UH).
Pinching danger
Risk of injury: The attraction force is so immense that it can result in hematomas, crushing, and broken bones. Use thick gloves.
Threat to navigation
GPS units and smartphones are highly susceptible to magnetism. Direct contact with a strong magnet can permanently damage the internal compass in your phone.
Protective goggles
Watch out for shards. Magnets can fracture upon violent connection, launching sharp fragments into the air. Eye protection is mandatory.
Keep away from computers
Do not bring magnets close to a purse, computer, or TV. The magnetic field can permanently damage these devices and wipe information from cards.
