Advantages and disadvantages of rare earth magnets.

Besides their high retention, neodymium magnets are valued for these benefits:

• Their power is maintained, and after approximately 10 years it decreases only by ~1% (theoretically),
• Neodymium magnets prove to be highly resistant to magnetic field loss caused by external interference,
• A magnet with a metallic silver surface is more attractive,
• Neodymium magnets create maximum magnetic induction on a small area, which ensures high operational effectiveness,
• 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 designing and the capacity to customize to unusual requirements,
• Huge importance in electronics industry – they find application in mass storage devices, electric motors, medical equipment, as well as other advanced devices.
• Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,

Disadvantages of NdFeB magnets:

• They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
• When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their power 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 suggest using waterproof magnets e.g. in rubber, plastic
• Due to limitations in producing nuts and complicated forms in magnets, we recommend using casing - magnetic holder.
• Possible danger related to microscopic parts of magnets are risky, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, small elements of these products are able to disrupt the diagnostic process medical after entering the body.
• Due to expensive raw materials, their price is higher than average,

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

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

• using a plate made of low-carbon steel, serving as a circuit closing element
• with a thickness minimum 10 mm
• with a plane cleaned and smooth
• with zero gap (no impurities)
• during detachment in a direction vertical to the mounting surface
• in neutral thermal conditions

Lifting capacity in practice – influencing factors

Real force impacted by specific conditions, including (from priority):

• Gap between magnet and steel – every millimeter of distance (caused e.g. by veneer or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
• Force direction – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
• Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
• Plate material – mild steel gives the best results. Alloy steels lower magnetic properties and lifting capacity.
• Surface finish – full contact is obtained only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
• Temperature – temperature increase causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.

* Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, however under attempts to slide the magnet the holding force is lower. Additionally, even a slight gap {between} the magnet and the plate reduces the load capacity.
