Strengths and weaknesses of neodymium magnets.

Besides their remarkable field intensity, neodymium magnets offer the following advantages:

• They virtually do not lose power, because even after ten years the performance loss is only ~1% (in laboratory conditions),
• Magnets effectively resist against loss of magnetization caused by external fields,
• A magnet with a metallic silver surface looks better,
• Magnetic induction on the top side of the magnet is exceptional,
• Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
• Thanks to versatility in forming and the capacity to adapt to client solutions,
• Key role in electronics industry – they are commonly used in HDD drives, brushless drives, precision medical tools, also modern systems.
• Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,

Cons of neodymium magnets: tips and applications.

• They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only shields 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 suggest our specialized [AH] magnets, which work effectively even at 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.
• Limited ability of producing nuts in the magnet and complex forms - recommended is cover - mounting mechanism.
• Potential hazard related to microscopic parts of magnets can be dangerous, in case of ingestion, which becomes key in the aspect of protecting the youngest. Additionally, small elements of these products are able to disrupt the diagnostic process medical after entering the body.
• High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities

Magnetic strength at its maximum – what contributes to it?

The load parameter shown represents the peak performance, obtained under ideal test conditions, namely:

• on a base made of structural steel, optimally conducting the magnetic flux
• with a thickness minimum 10 mm
• characterized by even structure
• without any air gap between the magnet and steel
• during pulling in a direction perpendicular to the plane
• in stable room temperature

Practical aspects of lifting capacity – factors

It is worth knowing that the magnet holding may be lower subject to the following factors, in order of importance:

• Clearance – existence of foreign body (paint, tape, air) acts as an insulator, which lowers capacity steeply (even by 50% at 0.5 mm).
• Angle of force application – maximum parameter is obtained only during perpendicular pulling. The shear force of the magnet along the surface is typically several times lower (approx. 1/5 of the lifting capacity).
• Element thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
• Material composition – different alloys reacts the same. High carbon content worsen the interaction with the magnet.
• Surface finish – ideal contact is obtained only on smooth steel. Any scratches and bumps create air cushions, reducing force.
• Operating temperature – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and at low temperatures gain strength (up to a certain limit).

* Lifting capacity was determined using a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, whereas under parallel forces the holding force is lower. In addition, even a minimal clearance {between} the magnet’s surface and the plate reduces the load capacity.
