Pros as well as cons of NdFeB magnets.

In addition to their long-term stability, neodymium magnets provide the following advantages:

• They have unchanged lifting capacity, and over nearly 10 years their performance decreases symbolically – ~1% (in testing),
• Magnets perfectly resist against demagnetization caused by external fields,
• A magnet with a metallic gold surface is more attractive,
• The surface of neodymium magnets generates a concentrated magnetic field – this is one of their assets,
• Through (appropriate) combination of ingredients, they can achieve high thermal strength, allowing for action at temperatures approaching 230°C and above...
• In view of the possibility of precise shaping and adaptation to unique solutions, NdFeB magnets can be created in a variety of geometric configurations, which amplifies use scope,
• Huge importance in future technologies – they are commonly used in mass storage devices, motor assemblies, medical devices, and modern systems.
• Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Disadvantages of NdFeB magnets:

• At strong impacts they can break, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
• NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
• They rust in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
• Limited possibility of producing nuts in the magnet and complicated shapes - recommended is a housing - mounting mechanism.
• Potential hazard to health – tiny shards of magnets pose a threat, in case of ingestion, which becomes key in the context of child safety. It is also worth noting that small components of these products are able to complicate diagnosis medical when they are in the body.
• With budget limitations the cost of neodymium magnets can be a barrier,

Maximum magnetic pulling force – what affects it?

Magnet power was determined for ideal contact conditions, including:

• on a base made of structural steel, effectively closing the magnetic flux
• with a thickness minimum 10 mm
• with an ideally smooth touching surface
• without the slightest air gap between the magnet and steel
• for force acting at a right angle (in the magnet axis)
• at temperature room level

Practical aspects of lifting capacity – factors

Real force is affected by specific conditions, such as (from most important):

• Air gap (between the magnet and the metal), because even a tiny clearance (e.g. 0.5 mm) results in a drastic drop in force by up to 50% (this also applies to varnish, rust or debris).
• Force direction – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the maximum value.
• Substrate thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet restricts the attraction force (the magnet "punches through" it).
• Plate material – mild steel gives the best results. Alloy admixtures reduce magnetic permeability and lifting capacity.
• Plate texture – ground elements ensure maximum contact, which improves field saturation. Rough surfaces weaken the grip.
• 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).

* Lifting capacity was assessed using a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, however under parallel forces the holding force is lower. Additionally, even a slight gap {between} the magnet’s surface and the plate lowers the load capacity.
