Strengths and weaknesses of NdFeB magnets.

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

• They do not lose strength, even after approximately 10 years – the drop in lifting capacity is only ~1% (theoretically),
• They retain their magnetic properties even under close interference source,
• By using a smooth coating of silver, the element presents an nice look,
• The surface of neodymium magnets generates a unique magnetic field – this is a distinguishing feature,
• 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 modularity in forming and the capacity to customize to specific needs,
• Versatile presence in advanced technology sectors – they are used in computer drives, electromotive mechanisms, medical devices, as well as complex engineering applications.
• Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,

Cons of neodymium magnets: application proposals

• Brittleness is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a steel housing, which not only protects them against impacts but also increases their durability
• Neodymium magnets decrease their power 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
• When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
• Due to limitations in realizing threads and complex shapes in magnets, we propose using casing - magnetic mechanism.
• Health risk resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Additionally, small components of these devices are able to be problematic in diagnostics medical in case of swallowing.
• Due to neodymium price, their price exceeds standard values,

Maximum lifting force for a neodymium magnet – what affects it?

The load parameter shown refers to the limit force, obtained under laboratory conditions, specifically:

• using a base made of high-permeability steel, serving as a magnetic yoke
• possessing a thickness of minimum 10 mm to avoid saturation
• with a surface free of scratches
• under conditions of ideal adhesion (metal-to-metal)
• for force acting at a right angle (in the magnet axis)
• at temperature approx. 20 degrees Celsius

Lifting capacity in real conditions – factors

Please note that the magnet holding will differ subject to elements below, starting with the most relevant:

• Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by veneer or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
• Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
• Plate thickness – insufficiently thick sheet causes magnetic saturation, causing part of the flux to be escaped into the air.
• Metal type – not every steel reacts the same. High carbon content weaken the interaction with the magnet.
• Base smoothness – the more even the surface, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
• Temperature – heating the magnet results in weakening of force. Check the maximum operating temperature for a given model.

* Lifting capacity was assessed by applying a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, however under parallel forces the load capacity is reduced by as much as 5 times. Additionally, even a small distance {between} the magnet and the plate reduces the holding force.
