Pros as well as cons of neodymium magnets.

Apart from their superior magnetism, neodymium magnets have these key benefits:

• They do not lose strength, even during approximately ten years – the decrease in power is only ~1% (based on measurements),
• Neodymium magnets are distinguished by exceptionally resistant to loss of magnetic properties caused by external field sources,
• By using a shiny coating of nickel, the element has an professional look,
• Magnetic induction on the top side of the magnet remains strong,
• Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
• Thanks to the ability of flexible forming and customization to custom projects, neodymium magnets can be modeled in a broad palette of forms and dimensions, which increases their versatility,
• Key role in innovative solutions – they are utilized in magnetic memories, electric motors, precision medical tools, and modern systems.
• Thanks to their power density, small magnets offer high operating force, with minimal size,

Disadvantages of neodymium magnets:

• To avoid cracks under impact, we recommend using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
• When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
• They oxidize in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
• Limited ability of producing threads in the magnet and complex forms - preferred is cover - magnetic holder.
• Possible danger resulting from small fragments of magnets can be dangerous, if swallowed, which gains importance in the context of child health protection. It is also worth noting that small elements of these products can disrupt the diagnostic process medical when they are in the body.
• High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Maximum magnetic pulling force – what contributes to it?

The force parameter is a theoretical maximum value conducted under standard conditions:

• using a base made of mild steel, serving as a ideal flux conductor
• possessing a thickness of min. 10 mm to ensure full flux closure
• characterized by even structure
• under conditions of no distance (metal-to-metal)
• for force applied at a right angle (pull-off, not shear)
• at ambient temperature room level

Practical lifting capacity: influencing factors

It is worth knowing that the working load will differ influenced by the following factors, in order of importance:

• Distance – existence of foreign body (rust, tape, gap) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
• Load vector – highest force is reached only during perpendicular pulling. The force required to slide of the magnet along the plate is standardly several times lower (approx. 1/5 of the lifting capacity).
• Base massiveness – insufficiently thick plate does not close the flux, causing part of the power to be wasted to the other side.
• Steel type – mild steel gives the best results. Alloy steels lower magnetic permeability and lifting capacity.
• Base smoothness – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Unevenness acts like micro-gaps.
• Operating temperature – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).

* Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under shearing force the lifting capacity is smaller. In addition, even a small distance {between} the magnet’s surface and the plate reduces the load capacity.
