Advantages as well as disadvantages of rare earth magnets.
Advantages
- They have unchanged lifting capacity, and over more than 10 years their attraction force decreases symbolically – ~1% (according to theory),
- Neodymium magnets are exceptionally resistant to demagnetization caused by magnetic disturbances,
- In other words, due to the reflective layer of nickel, the element is aesthetically pleasing,
- They feature high magnetic induction at the operating surface, which improves attraction properties,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- Possibility of detailed creating as well as optimizing to specific needs,
- Huge importance in innovative solutions – they are commonly used in hard drives, drive modules, precision medical tools, and technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which enables their usage in compact constructions
Weaknesses
- To avoid cracks under impact, we suggest using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
- Neodymium magnets lose their strength 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 stability even at temperatures up to 230°C
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Limited possibility of creating threads in the magnet and complex forms - preferred is a housing - magnet mounting.
- Health risk to health – tiny shards of magnets can be dangerous, in case of ingestion, which gains importance in the context of child safety. Furthermore, tiny parts of these products can disrupt the diagnostic process medical when they are in the body.
- With large orders the cost of neodymium magnets is economically unviable,
Holding force characteristics
Maximum lifting capacity of the magnet – what contributes to it?
- with the contact of a sheet made of low-carbon steel, ensuring maximum field concentration
- with a thickness of at least 10 mm
- with an ideally smooth contact surface
- under conditions of gap-free contact (metal-to-metal)
- during detachment in a direction vertical to the mounting surface
- at ambient temperature approx. 20 degrees Celsius
What influences lifting capacity in practice
- Clearance – the presence of any layer (rust, dirt, air) acts as an insulator, which reduces power steeply (even by 50% at 0.5 mm).
- Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
- Chemical composition of the base – mild steel gives the best results. Alloy admixtures lower magnetic permeability and lifting capacity.
- Surface quality – the smoother and more polished the surface, the better the adhesion and stronger the hold. Unevenness creates an air distance.
- Thermal factor – hot environment weakens pulling force. Too high temperature can permanently damage the magnet.
Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under parallel forces the holding force is lower. In addition, even a slight gap between the magnet and the plate decreases the lifting capacity.
Safety rules for work with neodymium magnets
This is not a toy
These products are not suitable for play. Swallowing several magnets may result in them connecting inside the digestive tract, which poses a severe health hazard and requires immediate surgery.
Do not underestimate power
Be careful. Rare earth magnets attract from a distance and connect with massive power, often faster than you can react.
Keep away from electronics
Be aware: neodymium magnets produce a field that interferes with sensitive sensors. Maintain a separation from your mobile, device, and navigation systems.
Magnet fragility
Despite metallic appearance, the material is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.
Pacemakers
Medical warning: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have electronic implants.
Threat to electronics
Do not bring magnets close to a wallet, laptop, or screen. The magnetism can irreversibly ruin these devices and wipe information from cards.
Heat sensitivity
Standard neodymium magnets (grade N) undergo demagnetization when the temperature goes above 80°C. This process is irreversible.
Crushing force
Large magnets can smash fingers instantly. Do not put your hand between two strong magnets.
Nickel coating and allergies
Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If redness appears, cease working with magnets and wear gloves.
Machining danger
Drilling and cutting of NdFeB material poses a fire hazard. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
