Pros as well as cons of neodymium magnets.

Besides their exceptional strength, neodymium magnets offer the following advantages:

• They retain magnetic properties for around 10 years – the drop is just ~1% (in theory),
• They possess excellent resistance to magnetic field loss due to opposing magnetic fields,
• Thanks to the metallic finish, the surface of Ni-Cu-Ni, gold-plated, or silver-plated gives an professional appearance,
• Magnets are characterized by excellent magnetic induction on the outer side,
• Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
• Due to the possibility of precise forming and customization to individualized solutions, neodymium magnets can be created in a variety of forms and dimensions, which amplifies use scope,
• Huge importance in high-tech industry – they find application in HDD drives, electric drive systems, advanced medical instruments, and other advanced devices.
• Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which allows their use in compact constructions

Drawbacks and weaknesses of neodymium magnets: tips and applications.

• Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a strong case, which not only secures them against impacts but also raises their durability
• Neodymium magnets lose their strength 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 magnets in rubber or plastics, which secure oxidation and corrosion.
• Limited ability of creating threads in the magnet and complicated forms - recommended is a housing - mounting mechanism.
• Potential hazard related to microscopic parts of magnets pose a threat, in case of ingestion, which gains importance in the aspect of protecting the youngest. Additionally, tiny parts of these devices are able to 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 increases costs of application in large quantities

Magnetic strength at its maximum – what affects it?

Information about lifting capacity is the result of a measurement for optimal configuration, assuming:

• on a plate made of mild steel, perfectly concentrating the magnetic flux
• with a thickness minimum 10 mm
• characterized by even structure
• under conditions of ideal adhesion (metal-to-metal)
• during detachment in a direction perpendicular to the mounting surface
• at ambient temperature room level

Lifting capacity in real conditions – factors

Bear in mind that the magnet holding will differ influenced by elements below, in order of importance:

• Distance (between the magnet and the metal), because even a microscopic distance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
• Load vector – maximum parameter is reached only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is standardly many times lower (approx. 1/5 of the lifting capacity).
• Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
• Steel grade – ideal substrate is high-permeability steel. Stainless steels may generate lower lifting capacity.
• Surface quality – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Roughness creates an air distance.
• Temperature – heating the magnet causes a temporary drop of induction. Check the maximum operating temperature for a given model.

* Lifting capacity was measured using a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, however under shearing force the lifting capacity is smaller. Moreover, even a small distance {between} the magnet’s surface and the plate decreases the holding force.
