Strengths and weaknesses of neodymium magnets.
Pros
- Their power is durable, and after around ten years it decreases only by ~1% (according to research),
- Magnets very well defend themselves against loss of magnetization caused by foreign field sources,
- A magnet with a shiny nickel surface looks better,
- Neodymium magnets ensure maximum magnetic induction on a small surface, which allows for strong attraction,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
- Thanks to modularity in constructing and the capacity to customize to specific needs,
- Wide application in innovative solutions – they serve a role in computer drives, motor assemblies, precision medical tools, and other advanced devices.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Limitations
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
- Neodymium magnets decrease their power 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 oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Limited possibility of producing nuts in the magnet and complicated shapes - preferred is cover - magnet mounting.
- Possible danger to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that tiny parts of these devices can disrupt the diagnostic process medical when they are in the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what it depends on?
- with the contact of a yoke made of special test steel, ensuring full magnetic saturation
- whose transverse dimension is min. 10 mm
- with an ideally smooth touching surface
- under conditions of ideal adhesion (metal-to-metal)
- under axial force direction (90-degree angle)
- at temperature room level
Practical aspects of lifting capacity – factors
- Clearance – the presence of foreign body (paint, tape, air) acts as an insulator, which lowers capacity steeply (even by 50% at 0.5 mm).
- Load vector – maximum parameter is reached only during pulling at a 90° angle. The force required to slide of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
- Steel grade – ideal substrate is pure iron steel. Stainless steels may generate lower lifting capacity.
- Smoothness – full contact is obtained only on smooth steel. Rough texture reduce the real contact area, reducing force.
- Temperature influence – high temperature reduces 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, however under attempts to slide the magnet the holding force is lower. Moreover, even a slight gap between the magnet’s surface and the plate lowers the load capacity.
Warnings
Serious injuries
Protect your hands. Two powerful magnets will snap together instantly with a force of massive weight, destroying everything in their path. Be careful!
Do not overheat magnets
Control the heat. Heating the magnet to high heat will destroy its properties and pulling force.
GPS Danger
Be aware: rare earth magnets produce a field that disrupts sensitive sensors. Keep a separation from your mobile, tablet, and navigation systems.
Life threat
People with a ICD must maintain an absolute distance from magnets. The magnetism can stop the functioning of the life-saving device.
Electronic hazard
Intense magnetic fields can erase data on payment cards, hard drives, and storage devices. Keep a distance of at least 10 cm.
Nickel coating and allergies
Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If an allergic reaction occurs, cease handling magnets and wear gloves.
Magnet fragility
Neodymium magnets are ceramic materials, which means they are fragile like glass. Impact of two magnets leads to them breaking into small pieces.
Do not drill into magnets
Fire hazard: Neodymium dust is highly flammable. Do not process magnets in home conditions as this risks ignition.
Product not for children
NdFeB magnets are not toys. Eating several magnets may result in them pinching intestinal walls, which poses a critical condition and requires immediate surgery.
Conscious usage
Exercise caution. Rare earth magnets attract from a distance and snap with massive power, often quicker than you can move away.
