1. Vertical hold

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

2. Steel thickness impact

*Thin steel (e.g. 0.5mm PC case) significantly limits the holding force.

3. Thermal stability

*For standard magnets, the safety limit is 80°C.

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.66

This simulation demonstrates the magnetic stability of the selected magnet under specific geometric conditions. 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 proposals

This product is an incredibly powerful cylinder magnet, composed of modern NdFeB material, which, with dimensions of Ø10x6 mm, guarantees the highest energy density. The MW 10x6 / N38 model features a tolerance of ±0.1mm and professional build quality, making it an ideal solution for the most demanding engineers and designers. As a cylindrical magnet with impressive force (approx. 3.38 kg), this product is in stock from our European logistics center, ensuring quick order fulfillment. Moreover, its Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.
It successfully proves itself in modeling, advanced robotics, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 33.12 N with a weight of only 3.53 g, this rod is indispensable in electronics and wherever low weight is crucial.
Since our magnets have a very precise dimensions, the best method is to glue them into holes with a slightly larger diameter (e.g., 10.1 mm) using two-component epoxy glues. To ensure long-term durability in industry, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.
Magnets NdFeB grade N38 are strong enough for the majority of applications in modeling and machine building, where excessive miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø10x6), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.
This model is characterized by dimensions Ø10x6 mm, which, at a weight of 3.53 g, makes it an element with impressive magnetic energy density. The value of 33.12 N means that the magnet is capable of holding a weight many times exceeding its own mass of 3.53 g. The product has a [NiCuNi] coating, which protects the surface against external factors, giving it an aesthetic, silvery shine.
Standardly, the magnetic axis runs through the center of the cylinder, causing the greatest attraction force to occur on the bases with a diameter of 10 mm. Such an arrangement is most desirable 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 through the diameter if your project requires it.

Advantages and disadvantages of Nd2Fe14B magnets.

Benefits

Besides their magnetic performance, neodymium magnets are valued for these benefits:
  • Their magnetic field remains stable, and after approximately ten years it drops only by ~1% (according to research),
  • They feature excellent resistance to magnetism drop due to opposing magnetic fields,
  • A magnet with a metallic nickel surface looks better,
  • Magnets possess impressive magnetic induction on the active area,
  • Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
  • Possibility of precise shaping and adjusting to complex applications,
  • Versatile presence in modern technologies – they serve a role in computer drives, electric motors, diagnostic systems, also industrial machines.
  • Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which allows their use in compact constructions

Disadvantages

Cons of neodymium magnets: tips and applications.
  • Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a steel housing, which not only secures them against impacts but also increases their durability
  • Neodymium magnets decrease their force 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. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
  • Limited possibility of making threads in the magnet and complex shapes - recommended is casing - mounting mechanism.
  • Potential hazard related to microscopic parts of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child safety. It is also worth noting that tiny parts of these devices can complicate diagnosis medical when they are in the body.
  • Due to neodymium price, their price is relatively high,

Pull force analysis

Breakaway strength of the magnet in ideal conditionswhat contributes to it?

The force parameter is a measurement result conducted under the following configuration:
  • on a base made of structural steel, optimally conducting the magnetic flux
  • whose transverse dimension reaches at least 10 mm
  • characterized by smoothness
  • without any clearance between the magnet and steel
  • during detachment in a direction perpendicular to the plane
  • in neutral thermal conditions

Practical aspects of lifting capacity – factors

Holding efficiency is affected by working environment parameters, including (from priority):
  • Clearance – the presence of foreign body (rust, tape, air) acts as an insulator, which reduces capacity rapidly (even by 50% at 0.5 mm).
  • Force direction – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet exhibits much less (often approx. 20-30% of nominal force).
  • Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
  • Steel type – low-carbon steel attracts best. Alloy admixtures reduce magnetic permeability and holding force.
  • Smoothness – full contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
  • Thermal environment – temperature increase results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.

Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under shearing force the lifting capacity is smaller. Additionally, even a small distance between the magnet and the plate decreases the lifting capacity.

Safe handling of neodymium magnets
Product not for children

Product intended for adults. Tiny parts pose a choking risk, causing intestinal necrosis. Store away from kids and pets.

Hand protection

Big blocks can break fingers in a fraction of a second. Never place your hand between two strong magnets.

Nickel allergy

Medical facts indicate that the nickel plating (the usual finish) is a common allergen. For allergy sufferers, avoid direct skin contact and select coated magnets.

Heat warning

Watch the temperature. Exposing the magnet to high heat will destroy its magnetic structure and strength.

Handling guide

Exercise caution. Neodymium magnets attract from a long distance and connect with huge force, often quicker than you can move away.

ICD Warning

People with a heart stimulator must keep an absolute distance from magnets. The magnetic field can stop the operation of the life-saving device.

Shattering risk

Watch out for shards. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. Eye protection is mandatory.

Magnetic interference

An intense magnetic field interferes with the operation of compasses in smartphones and GPS navigation. Do not bring magnets close to a smartphone to avoid damaging the sensors.

Fire warning

Machining of neodymium magnets poses a fire risk. Magnetic powder reacts violently with oxygen and is hard to extinguish.

Magnetic media

Avoid bringing magnets close to a purse, laptop, or screen. The magnetism can destroy these devices and wipe information from cards.
