Strengths as well as weaknesses of rare earth magnets.

Besides their durability, neodymium magnets are valued for these benefits:

• Their power is maintained, and after approximately ten years it drops only by ~1% (theoretically),
• Neodymium magnets are characterized by exceptionally resistant to magnetic field loss caused by external field sources,
• Thanks to the metallic finish, the layer of Ni-Cu-Ni, gold, or silver gives an professional appearance,
• The surface of neodymium magnets generates a concentrated 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...
• Possibility of detailed machining as well as adjusting to individual requirements,
• Fundamental importance in modern technologies – they are commonly used in magnetic memories, electric motors, diagnostic systems, as well as modern systems.
• Compactness – despite small sizes they generate large force, making them ideal for precision applications

Disadvantages of neodymium magnets:

• To avoid cracks under impact, we suggest using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
• We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
• Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
• Limited possibility of creating threads in the magnet and complex shapes - recommended is cover - magnet mounting.
• Potential hazard to health – tiny shards of magnets are risky, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small components of these magnets can complicate diagnosis medical in case of swallowing.
• With mass production the cost of neodymium magnets is a challenge,

Maximum lifting force for a neodymium magnet – what contributes to it?

The specified lifting capacity represents the limit force, measured under ideal test conditions, specifically:

• using a base made of high-permeability steel, acting as a ideal flux conductor
• whose thickness is min. 10 mm
• with a plane free of scratches
• with total lack of distance (without coatings)
• during pulling in a direction perpendicular to the plane
• at temperature room level

Practical aspects of lifting capacity – factors

Holding efficiency is affected by specific conditions, mainly (from most important):

• Gap (betwixt the magnet and the plate), because even a very small clearance (e.g. 0.5 mm) results in a drastic drop in force by up to 50% (this also applies to paint, corrosion or dirt).
• Load vector – highest force is obtained only during perpendicular pulling. The force required to slide of the magnet along the surface is usually many times lower (approx. 1/5 of the lifting capacity).
• Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
• Steel grade – ideal substrate is high-permeability steel. Cast iron may generate lower lifting capacity.
• Surface finish – ideal contact is possible only on polished steel. Rough texture create air cushions, reducing force.
• Thermal conditions – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).

* Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, whereas under shearing force the lifting capacity is smaller. In addition, even a slight gap {between} the magnet’s surface and the plate reduces the lifting capacity.
