Strengths and weaknesses of neodymium 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 attraction force decreases symbolically – ~1% (according to theory),
• Magnets effectively protect themselves against demagnetization caused by ambient magnetic noise,
• In other words, due to the smooth layer of nickel, the element gains visual value,
• They show high magnetic induction at the operating surface, which improves attraction properties,
• Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
• Possibility of detailed creating and modifying to atypical requirements,
• Universal use in future technologies – they are commonly used in HDD drives, electric motors, medical devices, and modern systems.
• Thanks to concentrated force, small magnets offer high operating force, with minimal size,

Problematic aspects of neodymium magnets and ways of using them

• Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a steel housing, which not only secures them against impacts but also raises their durability
• We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
• Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture
• Due to limitations in creating threads and complex shapes in magnets, we propose using a housing - magnetic holder.
• Possible danger resulting from small fragments of magnets pose a threat, in case of ingestion, which becomes key in the context of child health protection. Furthermore, small elements of these products are able to disrupt the diagnostic process medical in case of swallowing.
• With budget limitations the cost of neodymium magnets can be a barrier,

Best holding force of the magnet in ideal parameters – what it depends on?

The load parameter shown refers to the peak performance, obtained under optimal environment, namely:

• with the application of a sheet made of special test steel, ensuring maximum field concentration
• with a cross-section no less than 10 mm
• characterized by lack of roughness
• without any insulating layer between the magnet and steel
• under axial force vector (90-degree angle)
• at conditions approx. 20°C

Impact of factors on magnetic holding capacity in practice

In practice, the actual lifting capacity is determined by a number of factors, presented from the most important:

• Clearance – existence of foreign body (paint, tape, air) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
• Loading method – catalog parameter refers to detachment vertically. When slipping, the magnet exhibits much less (often approx. 20-30% of maximum force).
• Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
• Plate material – mild steel attracts best. Alloy admixtures reduce magnetic properties and holding force.
• Surface condition – smooth surfaces ensure maximum contact, which increases field saturation. Uneven metal reduce efficiency.
• Temperature influence – hot environment reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.

* Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under perpendicular forces, whereas under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Additionally, even a small distance {between} the magnet and the plate reduces the load capacity.
