Pros as well as cons of Nd2Fe14B magnets.
Strengths
- They have stable power, and over around 10 years their attraction force decreases symbolically – ~1% (according to theory),
- They do not lose their magnetic properties even under close interference source,
- In other words, due to the aesthetic surface of silver, the element looks attractive,
- Magnetic induction on the working part of the magnet turns out to be strong,
- 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...
- Possibility of detailed machining and adjusting to atypical requirements,
- Significant place in innovative solutions – they are commonly used in HDD drives, brushless drives, advanced medical instruments, and multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which allows their use in small systems
Weaknesses
- To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
- Neodymium magnets lose their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Limited possibility of creating nuts in the magnet and complicated shapes - recommended is a housing - magnetic holder.
- Health risk resulting from small fragments of magnets can be dangerous, in case of ingestion, which becomes key in the aspect of protecting the youngest. Additionally, tiny parts of these magnets are able to complicate diagnosis medical when they are in the body.
- Due to expensive raw materials, their price is higher than average,
Lifting parameters
Maximum holding power of the magnet – what contributes to it?
- using a plate made of low-carbon steel, functioning as a magnetic yoke
- whose transverse dimension reaches at least 10 mm
- with a surface free of scratches
- with zero gap (without coatings)
- during pulling in a direction vertical to the plane
- in neutral thermal conditions
Impact of factors on magnetic holding capacity in practice
- Space between surfaces – every millimeter of separation (caused e.g. by veneer or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Chemical composition of the base – low-carbon steel attracts best. Alloy admixtures lower magnetic permeability and lifting capacity.
- Surface structure – the more even the surface, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
- Temperature – temperature increase results in weakening of force. It is worth remembering the maximum operating temperature for a given model.
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under shearing force the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet and the plate reduces the load capacity.
Safe handling of NdFeB magnets
Magnetic interference
Navigation devices and smartphones are highly susceptible to magnetic fields. Direct contact with a powerful NdFeB magnet can permanently damage the sensors in your phone.
Adults only
Strictly keep magnets away from children. Risk of swallowing is significant, and the consequences of magnets connecting inside the body are very dangerous.
Fragile material
Despite the nickel coating, neodymium is brittle and cannot withstand shocks. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
Conscious usage
Be careful. Rare earth magnets act from a long distance and snap with massive power, often quicker than you can react.
Hand protection
Danger of trauma: The attraction force is so great that it can cause hematomas, pinching, and broken bones. Use thick gloves.
Health Danger
Medical warning: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.
Mechanical processing
Mechanical processing of NdFeB material poses a fire hazard. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Operating temperature
Watch the temperature. Exposing the magnet to high heat will permanently weaken its properties and strength.
Metal Allergy
It is widely known that the nickel plating (the usual finish) is a common allergen. For allergy sufferers, refrain from direct skin contact or opt for versions in plastic housing.
Keep away from computers
Very strong magnetic fields can corrupt files on credit cards, HDDs, and storage devices. Stay away of min. 10 cm.
