Advantages as well as disadvantages of neodymium magnets.
Pros
- They retain magnetic properties for nearly ten years – the drop is just ~1% (in theory),
- Neodymium magnets are characterized by highly resistant to magnetic field loss caused by magnetic disturbances,
- By using a decorative coating of gold, the element acquires an aesthetic look,
- Magnetic induction on the working part of the magnet remains extremely intense,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Thanks to the ability of accurate molding and customization to custom projects, neodymium magnets can be manufactured in a variety of forms and dimensions, which expands the range of possible applications,
- Huge importance in electronics industry – they are used in mass storage devices, motor assemblies, medical equipment, also complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which makes them useful in compact constructions
Limitations
- To avoid cracks under impact, we suggest using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
- Neodymium magnets decrease 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 stability even at temperatures up to 230°C
- They rust in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Limited possibility of creating nuts in the magnet and complicated shapes - preferred is cover - mounting mechanism.
- Possible danger related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which is particularly important in the context of child safety. Furthermore, small elements of these magnets can disrupt the diagnostic process medical after entering the body.
- 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 holding power of the magnet – what it depends on?
- on a block made of structural steel, perfectly concentrating the magnetic field
- with a cross-section no less than 10 mm
- with a surface free of scratches
- without the slightest insulating layer between the magnet and steel
- during pulling in a direction perpendicular to the mounting surface
- in stable room temperature
Magnet lifting force in use – key factors
- Gap between surfaces – every millimeter of separation (caused e.g. by varnish or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
- Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
- Plate material – low-carbon steel gives the best results. Alloy steels decrease magnetic permeability and holding force.
- Surface finish – full contact is obtained only on polished steel. Rough texture reduce the real contact area, reducing force.
- Thermal factor – hot environment weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity was measured using a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, however under parallel forces the load capacity is reduced by as much as 75%. Moreover, even a slight gap between the magnet and the plate lowers the load capacity.
Warnings
Crushing risk
Watch your fingers. Two powerful magnets will join instantly with a force of several hundred kilograms, destroying anything in their path. Be careful!
Metal Allergy
Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If an allergic reaction occurs, immediately stop working with magnets and wear gloves.
Dust is flammable
Dust produced during grinding of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
Magnetic interference
Navigation devices and mobile phones are extremely susceptible to magnetism. Direct contact with a powerful NdFeB magnet can decalibrate the internal compass in your phone.
ICD Warning
Health Alert: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.
Handling guide
Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Be predictive.
Electronic hazard
Intense magnetic fields can destroy records on payment cards, hard drives, and other magnetic media. Maintain a gap of min. 10 cm.
Do not overheat magnets
Keep cool. Neodymium magnets are sensitive to temperature. If you need resistance above 80°C, inquire about HT versions (H, SH, UH).
Magnet fragility
Protect your eyes. Magnets can explode upon violent connection, ejecting shards into the air. We recommend safety glasses.
No play value
Strictly store magnets out of reach of children. Ingestion danger is high, and the consequences of magnets connecting inside the body are tragic.
