Advantages as well as disadvantages of neodymium magnets.
Pros
- They retain magnetic properties for around ten years – the loss is just ~1% (in theory),
- They possess excellent resistance to weakening of magnetic properties when exposed to opposing magnetic fields,
- Thanks to the metallic finish, the plating of Ni-Cu-Ni, gold, or silver-plated gives an elegant appearance,
- The surface of neodymium magnets generates a maximum magnetic field – this is a key feature,
- 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...
- Due to the potential of accurate forming and adaptation to individualized requirements, NdFeB magnets can be manufactured in a variety of geometric configurations, which makes them more universal,
- Key role in future technologies – they are utilized in computer drives, motor assemblies, medical equipment, as well as industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which makes them useful in small systems
Cons
- To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
- Neodymium magnets lose their force 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- Due to limitations in producing nuts and complicated shapes in magnets, we recommend using a housing - magnetic holder.
- Potential hazard resulting from small fragments of magnets are risky, when accidentally swallowed, which is particularly important in the context of child health protection. Additionally, tiny parts of these products can complicate diagnosis medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Maximum magnetic pulling force – what contributes to it?
- on a base made of structural steel, effectively closing the magnetic field
- with a thickness no less than 10 mm
- characterized by lack of roughness
- under conditions of ideal adhesion (metal-to-metal)
- during detachment in a direction vertical to the plane
- in neutral thermal conditions
Lifting capacity in real conditions – factors
- Clearance – the presence of any layer (paint, dirt, air) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
- Force direction – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Base massiveness – too thin steel does not close the flux, causing part of the flux to be lost into the air.
- Steel grade – the best choice is pure iron steel. Stainless steels may attract less.
- Surface quality – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Roughness acts like micro-gaps.
- Heat – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).
Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the lifting capacity is smaller. Moreover, even a slight gap between the magnet’s surface and the plate decreases the lifting capacity.
Precautions when working with NdFeB magnets
Machining danger
Combustion risk: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this risks ignition.
Heat warning
Keep cool. Neodymium magnets are susceptible to temperature. If you require operation above 80°C, ask us about special high-temperature series (H, SH, UH).
Precision electronics
Navigation devices and smartphones are extremely susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can ruin the internal compass in your phone.
Electronic hazard
Do not bring magnets near a wallet, laptop, or TV. The magnetism can irreversibly ruin these devices and erase data from cards.
Finger safety
Protect your hands. Two large magnets will join instantly with a force of massive weight, crushing anything in their path. Exercise extreme caution!
Allergy Warning
Nickel alert: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction happens, immediately stop working with magnets and use protective gear.
Life threat
Life threat: Strong magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.
Keep away from children
Neodymium magnets are not suitable for play. Accidental ingestion of a few magnets may result in them attracting across intestines, which constitutes a critical condition and requires immediate surgery.
Shattering risk
NdFeB magnets are ceramic materials, which means they are prone to chipping. Collision of two magnets leads to them shattering into small pieces.
Safe operation
Before use, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.
