Frequently asked questions

Where can I buy strong cylindrical neodymium magnets?
See the available cylinders in the DHIT catalogue. Compare dimensions, grade and the pull-force value on each product card; grade alone does not determine the pull force of a finished magnet.
Can a small cylindrical magnet provide a strong grip for precise workshop work?
Yes, but size alone is not enough to predict the result. Geometry, the steel surface and the direction of load affect the grip. Compare the specifications of the selected dimensions on their product cards.
Which cylindrical magnet can work at a higher temperature?
Check the operating-temperature limit of the particular model rather than assuming one limit for all N grades. The offered N52 models are rated up to 60°C. For hotter applications, ask for a product with a confirmed specification for the actual working temperature.

Magnetic force decreases significantly with every mm of gap. Keep in mind that even a very thin break (e.g., contamination, paint, rust) significantly reduces the pull force. Neodymiums work optimally in perfect adhesion; gap drastically cuts the power. Analyze how quickly the pull force plummet, when the product does not adhere directly to the steel surface. When designing the mounting, discard redundant distances.

This section defines the estimated force required to cause the slippage of the magnet vertically along a upright steel plate (considering standard friction). The holding force is relative to the distance between the magnet and the metal.

When hanging a holder on a upright surface (e.g., a fridge), it will maintain only approx. 20%-30% of nominal attraction strength. Gravity as well as a low friction coefficient mean that holders slip easier than they pop off the substrate. Designing a wall mount? Consider that the sliding force is much weaker than the perpendicular breakaway force. On a painted metal, the element will give way down under a much lighter weight. Utilizing a rubberized coating can drastically improve the result.

A thin metal plate is not enough to focus the entire magnetic field, which wastes potential of the holder. Should you install a neodymium to a too thin substrate, the flux will penetrate right through and the holding will be smaller. To squeeze the maximum of this neodymium's potential, you require a sufficiently solid piece of metal. The saturation effect means that on sheet metal structures (e.g., thin profiles), the product shows lower pull force. We advise picking the steel cross-section from these parameters.

The table estimates the reversible force change relative to 20°C, assuming a Br coefficient of -0.11%/°C and force proportional to Br². This is a simplified model with unchanged contact and geometry, not a measurement. Above the material limit, neither force nor irreversible magnetization loss is predicted.
The temperature limit comes from this product’s material data. Permissible conditions also depend on geometry and the magnetic circuit. Without B-H curves for the specific grade and temperature, Pc alone does not determine irreversible demagnetization. Values within the material range do not guarantee the allowable temperature of the complete assembly.

Two strong neodymiums attract each other from a significantly greater distance than a magnet and sheet setup. The connection of magnet-to-magnet creates a more powerful interaction and a wider radius of action. Planning to create a strong closure? Use a pair of magnets instead of one magnet and a striker plate. Remember that when connecting a pair of magnets, the impact force is extreme. The levitation is marginally weaker than the attraction, but still significant.
*Flux density between like poles is approximately ~0 Gs at the geometric center between the magnets (resulting from vector opposition).
Note: Figures apply to shear force of dual identical neodymium magnets (friction ~0.15 for Ni-Ni layer).

Neodymium magnets are very brittle – a strong collision with metal can result in shattering. Watch the impact speed – a magnet released freely speeds with massive force. Kinetic force can destroy the magnet or injury to skin. Be sure to control the product during bringing near metal so it doesn't hit with great force against the metal. A collision at high speed means shattering of the neodymium. Wear eye protection when working with powerful specimens.

Corrosion warning: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.
Water displaces steel, making heavy objects slightly lighter. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Wall mount (shear)

*Caution: On a vertical surface, the magnet retains merely a fraction of its perpendicular strength.

2. Steel thickness impact

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

3. Power loss vs temp

N38: the maximum material working temperature is 80°C. Permitted conditions also depend on the shape and magnetic circuit.

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.29

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.

This product is a very strong cylindrical magnet, produced from modern NdFeB material, which, at dimensions of Ø15x3 mm, guarantees optimal power. The MW 15x3 zestaw 50 szt. / N38 model boasts high dimensional repeatability and professional build quality, making it an ideal solution for the most demanding engineers and designers. As a cylindrical magnet with impressive force (approx. 2.87 kg), this product is in stock from our European logistics center, ensuring quick order fulfillment. Furthermore, its Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.
This model is ideal for building generators, advanced sensors, and efficient magnetic separators, where maximum induction on a small surface counts. Thanks to the pull force of 28.14 N with a weight of only 199 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., 15.1 mm) using two-component epoxy glues. To ensure stability in industry, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.
Choose the material grade together with the dimensions and working conditions. A grade designation alone does not determine the pull force of the finished magnet. Check the properties and working temperature of this specific model on its product card; contact us before ordering for an unusual application.
This model is characterized by dimensions Ø15x3 mm, which, at a weight of 199 g, makes it an element with high magnetic energy density. The value of 28.14 N means that the magnet is capable of holding a weight many times exceeding its own mass of 199 g. The product has a [NiCuNi] coating, which secures it against oxidation, 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 15 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 diametrically if your project requires it.

Advantages and disadvantages of Nd2Fe14B magnets.

Advantages

In addition to their pulling strength, neodymium magnets provide the following advantages:
  • They have constant strength, and over more than ten years their performance decreases symbolically – ~1% (according to theory),
  • They do not lose their magnetic properties even under external field action,
  • Thanks to the glossy finish, the layer of Ni-Cu-Ni, gold-plated, or silver gives an clean appearance,
  • The surface of neodymium magnets generates a powerful magnetic field – this is a key feature,
  • Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
  • Thanks to flexibility in shaping and the ability to modify to client solutions,
  • Fundamental importance in advanced technology sectors – they are used in data components, electric drive systems, medical equipment, as well as complex engineering applications.
  • Thanks to concentrated force, small magnets offer high operating force, with minimal size,

Disadvantages

Disadvantages of neodymium magnets:
  • Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a strong case, which not only secures them against impacts but also raises their durability
  • Do not exceed this material temperature limit: 80°C. Overheating may permanently weaken the magnet.
  • Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
  • Due to limitations in creating nuts and complex forms in magnets, we propose using a housing - magnetic mechanism.
  • Health risk resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child health protection. Furthermore, tiny parts of these devices can complicate diagnosis medical after entering the body.
  • High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Lifting parameters

Detachment force of the magnet in optimal conditions – what it depends on?

Magnet power is the result of a measurement for the most favorable conditions, taking into account:
  • on a block made of mild steel, effectively closing the magnetic flux
  • whose transverse dimension is min. 10 mm
  • characterized by even structure
  • with direct contact (without impurities)
  • during detachment in a direction perpendicular to the mounting surface
  • at temperature approx. 20 degrees Celsius

Practical aspects of lifting capacity – factors

Bear in mind that the magnet holding may be lower depending on elements below, in order of importance:
  • Gap (between the magnet and the metal), since even a very small clearance (e.g. 0.5 mm) leads to a drastic drop in force by up to 50% (this also applies to paint, corrosion or debris).
  • Force direction – declared lifting capacity refers to detachment vertically. When slipping, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
  • Base massiveness – too thin plate causes magnetic saturation, causing part of the power to be lost to the other side.
  • Material type – ideal substrate is high-permeability steel. Hardened steels may attract less.
  • Surface quality – the smoother and more polished the plate, the better the adhesion and stronger the hold. Unevenness creates an air distance.
  • Heat – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).

Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the load capacity is reduced by as much as fivefold. In addition, even a slight gap between the magnet and the plate reduces the holding force.

Precautions when working with NdFeB magnets
Do not drill into magnets

Machining of NdFeB material poses a fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.

Danger to pacemakers

For implant holders: Powerful magnets disrupt electronics. Maintain minimum 30 cm distance or request help to handle the magnets.

Handling rules

Handle with care. Neodymium magnets attract from a distance and connect with massive power, often quicker than you can move away.

Swallowing risk

These products are not intended for children. Swallowing several magnets may result in them connecting inside the digestive tract, which poses a critical condition and requires immediate surgery.

Keep away from electronics

Remember: rare earth magnets generate a field that disrupts sensitive sensors. Maintain a separation from your mobile, tablet, and navigation systems.

Material brittleness

Neodymium magnets are sintered ceramics, meaning they are fragile like glass. Clashing of two magnets leads to them shattering into small pieces.

Safe distance

Intense magnetic fields can destroy records on payment cards, HDDs, and other magnetic media. Stay away of min. 10 cm.

Maximum temperature

Do not exceed the maximum operating temperature stated in the specifications of the particular product. The limit depends on the material, geometry and operating arrangement; there is no single threshold for all neodymium magnets. Overheating can permanently weaken a magnet.

Serious injuries

Big blocks can smash fingers instantly. Never put your hand between two attracting surfaces.

Warning for allergy sufferers

Certain individuals have a contact allergy to nickel, which is the standard coating for neodymium magnets. Prolonged contact can result in an allergic reaction. We recommend use safety gloves.
