Advantages as well as disadvantages of neodymium magnets.

Besides their stability, neodymium magnets are valued for these benefits:

• Their power remains stable, and after around ten years it decreases only by ~1% (theoretically),
• They possess excellent resistance to magnetism drop when exposed to opposing magnetic fields,
• A magnet with a smooth gold surface looks better,
• Magnetic induction on the working part of the magnet turns out to be strong,
• Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
• Possibility of individual shaping as well as modifying to specific applications,
• Universal use in advanced technology sectors – they serve a role in HDD drives, drive modules, medical equipment, as well as multitasking production systems.
• Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which makes them useful in small systems

Characteristics of disadvantages of neodymium magnets: application proposals

• They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also increases its resistance to damage
• 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 rust. Therefore when using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
• We recommend casing - magnetic mechanism, due to difficulties in producing threads inside the magnet and complicated forms.
• Health risk resulting from small fragments of magnets pose a threat, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Additionally, small elements of these magnets can disrupt the diagnostic process medical in case of swallowing.
• High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities

Maximum lifting force for a neodymium magnet – what it depends on?

The lifting capacity listed is a theoretical maximum value performed under the following configuration:

• with the application of a yoke made of special test steel, guaranteeing full magnetic saturation
• possessing a thickness of at least 10 mm to avoid saturation
• with an ideally smooth touching surface
• under conditions of ideal adhesion (metal-to-metal)
• under axial force direction (90-degree angle)
• at standard ambient temperature

Lifting capacity in real conditions – factors

Holding efficiency impacted by working environment parameters, such as (from priority):

• Distance – existence of any layer (paint, dirt, air) acts as an insulator, which reduces capacity rapidly (even by 50% at 0.5 mm).
• Loading method – catalog parameter refers to pulling vertically. When attempting to slide, the magnet holds significantly lower power (typically approx. 20-30% of maximum force).
• Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
• Material composition – different alloys attracts identically. Alloy additives weaken the interaction with the magnet.
• Plate texture – smooth surfaces ensure maximum contact, which improves force. Uneven metal reduce efficiency.
• Thermal conditions – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and in frost gain strength (up to a certain limit).

* Lifting capacity testing was carried out on a smooth plate of suitable thickness, under a perpendicular pulling force, in contrast under parallel forces the load capacity is reduced by as much as fivefold. Moreover, even a slight gap {between} the magnet and the plate decreases the load capacity.
