Advantages and disadvantages of rare earth magnets.
Pros
- Their strength is durable, and after around ten years it drops only by ~1% (theoretically),
- Magnets very well defend themselves against loss of magnetization caused by foreign field sources,
- In other words, due to the shiny finish of gold, the element is aesthetically pleasing,
- Neodymium magnets ensure maximum magnetic induction on a small surface, which increases force concentration,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Possibility of precise forming and adapting to atypical requirements,
- Significant place in modern industrial fields – they serve a role in HDD drives, brushless drives, diagnostic systems, and complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which makes them useful in miniature devices
Weaknesses
- To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop 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 very resistant to heat
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
- Due to limitations in producing nuts and complex shapes in magnets, we recommend using cover - magnetic mechanism.
- Possible danger resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small elements of these devices are able to complicate diagnosis medical when they are in the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Best holding force of the magnet in ideal parameters – what it depends on?
- using a plate made of mild steel, functioning as a ideal flux conductor
- with a cross-section minimum 10 mm
- characterized by even structure
- with total lack of distance (without coatings)
- under perpendicular application of breakaway force (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Magnet lifting force in use – key factors
- Air gap (betwixt the magnet and the metal), since even a very small clearance (e.g. 0.5 mm) can cause a reduction in force by up to 50% (this also applies to varnish, corrosion or debris).
- Load vector – maximum parameter is available only during perpendicular pulling. The resistance to sliding of the magnet along the surface is usually many times lower (approx. 1/5 of the lifting capacity).
- Element thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Material type – ideal substrate is high-permeability steel. Hardened steels may generate lower lifting capacity.
- Base smoothness – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
- Thermal factor – hot environment reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.
Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.
Safety rules for work with neodymium magnets
Allergy Warning
Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If skin irritation occurs, cease working with magnets and use protective gear.
Fragile material
Despite metallic appearance, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.
Electronic hazard
Do not bring magnets close to a purse, laptop, or screen. The magnetism can destroy these devices and wipe information from cards.
Handling guide
Use magnets consciously. Their powerful strength can surprise even experienced users. Plan your moves and do not underestimate their force.
Swallowing risk
These products are not toys. Accidental ingestion of several magnets may result in them connecting inside the digestive tract, which poses a severe health hazard and requires urgent medical intervention.
Health Danger
Health Alert: Neodymium magnets can deactivate pacemakers and defibrillators. Do not approach if you have medical devices.
GPS Danger
An intense magnetic field disrupts the operation of compasses in smartphones and GPS navigation. Keep magnets close to a device to avoid breaking the sensors.
Crushing risk
Big blocks can break fingers in a fraction of a second. Do not place your hand between two attracting surfaces.
Combustion hazard
Powder created during grinding of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.
Demagnetization risk
Control the heat. Heating the magnet above 80 degrees Celsius will ruin its properties and pulling force.
