1. Sliding resistance

*Caution: On a vertical surface, the magnet holds just a fraction of its nominal pull.

2. Efficiency vs thickness

*Thin metal sheet (e.g. 0.5mm PC case) drastically limits the holding force.

3. Power loss vs temp

*For N38 grade, the critical limit is 80°C.

4. Demagnetization curve and operating point (B-H)

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.55

The chart above illustrates the magnetic characteristics of the material within the second quadrant of the hysteresis loop. The solid red line represents the demagnetization curve (material potential), while the dashed blue line is the load line based on the magnet's geometry. The Pc (Permeance Coefficient), also known as the load line slope, is a dimensionless value that describes the relationship between the magnet's shape and its magnetic stability. The intersection of these two lines (the black dot) is the operating point — it determines the actual magnetic flux density generated by the magnet in this specific configuration. A higher Pc value means the magnet is more 'slender' (tall relative to its area), resulting in a higher operating point and better resistance to irreversible demagnetization caused by external fields or temperature. A value of 0.42 is relatively low (typical for flat magnets), meaning the operating point is closer to the 'knee' of the curve — caution is advised when operating at temperatures near the maximum limit to avoid strength loss.

Other products

The offered product is an exceptionally strong cylinder magnet, composed of durable NdFeB material, which, at dimensions of Ø22x10 mm, guarantees maximum efficiency. This specific item boasts high dimensional repeatability and industrial build quality, making it an excellent solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 14.75 kg), this product is in stock from our European logistics center, ensuring lightning-fast order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating effectively protects it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.
It successfully proves itself in DIY projects, advanced robotics, and broadly understood industry, serving as a fastening or actuating element. Thanks to the high power of 144.65 N with a weight of only 28.51 g, this rod is indispensable in electronics and wherever every gram matters.
Due to the brittleness of the NdFeB material, you must not use force-fitting (so-called press-fit), as this risks immediate cracking of this professional component. To ensure long-term durability in industry, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.
Grade N38 is the most popular standard for industrial neodymium magnets, offering an optimal price-to-power ratio and high resistance to demagnetization. If you need the strongest magnets in the same volume (Ø22x10), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.
The presented product is a neodymium magnet with precisely defined parameters: diameter 22 mm and height 10 mm. The key parameter here is the holding force amounting to approximately 14.75 kg (force ~144.65 N), which, with such defined dimensions, proves the high power of the NdFeB material. The product has a [NiCuNi] coating, which secures it against oxidation, giving it an aesthetic, silvery shine.
This rod magnet is magnetized axially (along the height of 10 mm), which means that the N and S poles are located on the flat, circular surfaces. Such an arrangement is standard when connecting magnets in stacks (e.g., in filters) or when mounting in sockets at the bottom of a hole. On request, we can also produce versions magnetized diametrically if your project requires it.

Pros and cons of rare earth magnets.

Advantages

Besides their remarkable field intensity, neodymium magnets offer the following advantages:
  • They have stable power, and over more than 10 years their attraction force decreases symbolically – ~1% (in testing),
  • They are noted for resistance to demagnetization induced by external field influence,
  • Thanks to the reflective finish, the layer of Ni-Cu-Ni, gold-plated, or silver gives an professional appearance,
  • Neodymium magnets achieve maximum magnetic induction on a small area, which ensures high operational effectiveness,
  • Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
  • Considering the potential of flexible molding and adaptation to specialized projects, neodymium magnets can be created in a wide range of shapes and sizes, which makes them more universal,
  • Significant place in high-tech industry – they are commonly used in magnetic memories, motor assemblies, medical equipment, and multitasking production systems.
  • Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,

Weaknesses

Cons of neodymium magnets and ways of using them
  • They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
  • NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
  • When exposed to humidity, magnets usually 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 making nuts in the magnet and complicated forms - recommended is casing - mounting mechanism.
  • Health risk related to microscopic parts of magnets pose a threat, in case of ingestion, which becomes key in the aspect of protecting the youngest. It is also worth noting that tiny parts of these products are able to complicate diagnosis medical after entering the body.
  • Due to expensive raw materials, their price exceeds standard values,

Lifting parameters

Maximum holding power of the magnet – what affects it?

The specified lifting capacity refers to the maximum value, recorded under optimal environment, meaning:
  • on a base made of mild steel, effectively closing the magnetic flux
  • with a thickness of at least 10 mm
  • with a surface cleaned and smooth
  • without any insulating layer between the magnet and steel
  • under vertical application of breakaway force (90-degree angle)
  • in stable room temperature

Magnet lifting force in use – key factors

In practice, the real power results from a number of factors, ranked from most significant:
  • Space between surfaces – every millimeter of separation (caused e.g. by varnish or dirt) diminishes the pulling force, often by half at just 0.5 mm.
  • Angle of force application – highest force is available only during pulling at a 90° angle. The force required to slide of the magnet along the plate is usually several times lower (approx. 1/5 of the lifting capacity).
  • Base massiveness – too thin steel does not accept the full field, causing part of the flux to be lost into the air.
  • Steel type – low-carbon steel gives the best results. Alloy steels reduce magnetic permeability and lifting capacity.
  • Plate texture – smooth surfaces ensure maximum contact, which improves field saturation. Rough surfaces reduce efficiency.
  • Operating temperature – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and in frost gain strength (up to a certain limit).

Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under attempts to slide the magnet the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate reduces the holding force.

Safety rules for work with NdFeB magnets
Allergy Warning

A percentage of the population suffer from a hypersensitivity to Ni, which is the standard coating for NdFeB magnets. Frequent touching might lead to skin redness. We suggest use safety gloves.

Protective goggles

Beware of splinters. Magnets can explode upon violent connection, ejecting sharp fragments into the air. Eye protection is mandatory.

Compass and GPS

GPS units and smartphones are extremely sensitive to magnetism. Close proximity with a strong magnet can ruin the internal compass in your phone.

Health Danger

Individuals with a ICD have to maintain an safe separation from magnets. The magnetism can interfere with the functioning of the implant.

Conscious usage

Be careful. Neodymium magnets act from a long distance and snap with massive power, often faster than you can react.

Dust explosion hazard

Fire warning: Neodymium dust is explosive. Avoid machining magnets in home conditions as this may cause fire.

Protect data

Data protection: Strong magnets can ruin payment cards and sensitive devices (pacemakers, medical aids, mechanical watches).

Danger to the youngest

These products are not suitable for play. Swallowing several magnets may result in them pinching intestinal walls, which poses a direct threat to life and requires urgent medical intervention.

Permanent damage

Avoid heat. NdFeB magnets are susceptible to heat. If you require resistance above 80°C, ask us about special high-temperature series (H, SH, UH).

Pinching danger

Danger of trauma: The attraction force is so great that it can cause blood blisters, crushing, and broken bones. Protective gloves are recommended.
