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 sharply with every subsequent millimeter of spacing. Remember that even the smallest gap (e.g., dirt, varnish, rust) strongly diminishes the holding power. Magnets operate most effectively at the point of direct contact; distance nullifies the power. Notice how flashily the load capacity fall, when the magnet does not touch tightly to the steel surface. When designing the mounting, discard unnecessary gaps.

The following data shows the approximate holding capacity necessary to start the sliding of the magnet vertically on a upright metal surface (considering standard friction). This parameter is a function of the distance between the magnet and the surface.

When placing a holder on a upright surface (e.g., a board), it will only hold only about 20%-30% of its maximum pull force. Gravitational force and a low friction coefficient mean that magnets move down faster than they pull off. Planning a wall mount? Note that the sliding force is much weaker than the maximum static pull force. On a slippery surface, the magnet will give way down under a much lighter weight. Application of an anti-slip coating can drastically increase the grip.

A thin sheet is not enough to take in the entire magnetic field, which wastes potential of the magnet. If you install a neodymium to a thin surface, the flux will penetrate right through and the holding will be smaller. To utilize the maximum of this magnet's power, you require a sufficiently solid backing of steel. The saturation effect means that on delicate walls (e.g., car bodies), the holder shows lower pull force. We advise picking the steel cross-section according to the table below.

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 magnetic products interact from a much further distance than a magnet and sheet setup. The setup of magnet-to-magnet creates a more powerful interaction and a further horizon of operation. Designing a powerful holder? Apply two magnets instead of one magnet and a striker plate. Be careful that when connecting a pair of magnets, the pinch force is massive. The repulsion force is a bit weaker than the connection force, but still large.
*Flux density in repulsion mode reaches ~0 Gs at the geometric center of the gap (resulting from vector opposition).
Important: Calculations apply to friction force of two identical neodymium magnets (friction ~0.15 for Ni-Ni coating).

Neodymium magnets are very brittle – a strong collision with metal can result in shattering. Pay attention to connection velocity – a neodymium left loose becomes dangerous. Striking energy can destroy the magnet or painful pinches to skin. Be sure to control the product during bringing near metal so it doesn't slam with momentum against the steel surface. A contact at a velocity of dozens of km/h means shattering of the magnet. Use safety goggles when handling with powerful specimens.

Warning: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!
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. Vertical hold

*Warning: On a vertical wall, the magnet holds merely ~20% of its nominal pull.

2. Plate thickness effect

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

3. Thermal stability

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) = 0.17

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. At low Pc values (typical for flat magnets, below about 1) 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.

The offered product is an extremely powerful cylinder magnet, manufactured from advanced NdFeB material, which, with dimensions of Ø18x2 mm, guarantees the highest energy density. This specific item features high dimensional repeatability and industrial build quality, making it an excellent solution for the most demanding engineers and designers. As a cylindrical magnet with significant force (approx. 1.58 kg), this product is in stock from our European logistics center, ensuring lightning-fast order fulfillment. Furthermore, its triple-layer 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 field concentration on a small surface counts. Thanks to the pull force of 15.49 N with a weight of only 3.82 g, this cylindrical magnet is indispensable in miniature devices and wherever low weight is crucial.
Due to the delicate structure of the ceramic sinter, you must not use force-fitting (so-called press-fit), as this risks immediate cracking of this precision component. To ensure long-term durability in automation, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing durability 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.
The presented product is a neodymium magnet with precisely defined parameters: diameter 18 mm and height 2 mm. The value of 15.49 N means that the magnet is capable of holding a weight many times exceeding its own mass of 3.82 g. The product has a [NiCuNi] coating, which secures it against oxidation, giving it an aesthetic, silvery shine.
This cylinder is magnetized axially (along the height of 2 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 as well as cons of Nd2Fe14B magnets.

Pros

Besides their stability, neodymium magnets are valued for these benefits:
  • They retain full power for nearly 10 years – the loss is just ~1% (based on simulations),
  • They are noted for resistance to demagnetization induced by presence of other magnetic fields,
  • By using a smooth layer of nickel, the element acquires an proper look,
  • The surface of neodymium magnets generates a strong magnetic field – this is one of their assets,
  • Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling operation at temperatures approaching 230°C and above...
  • In view of the ability of free shaping and customization to unique solutions, neodymium magnets can be produced in a broad palette of forms and dimensions, which amplifies use scope,
  • Universal use in future technologies – they find application in mass storage devices, electric drive systems, precision medical tools, as well as modern systems.
  • Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which makes them useful in miniature devices

Limitations

Cons of neodymium magnets: application proposals
  • To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
  • Do not exceed this material temperature limit: 80°C. Overheating may permanently weaken the magnet.
  • Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
  • Due to limitations in creating nuts and complex forms in magnets, we recommend using casing - magnetic holder.
  • Potential hazard resulting from small fragments of magnets are risky, if swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, small elements of these magnets are able to be problematic in diagnostics medical when they are in the body.
  • With large orders the cost of neodymium magnets is a challenge,

Lifting parameters

Maximum lifting force for a neodymium magnet – what affects it?

Holding force of 1.58 kg is a result of laboratory testing performed under standard conditions:
  • using a plate made of mild steel, acting as a magnetic yoke
  • whose transverse dimension reaches at least 10 mm
  • with a plane free of scratches
  • without the slightest insulating layer between the magnet and steel
  • during pulling in a direction perpendicular to the mounting surface
  • at standard ambient temperature

What influences lifting capacity in practice

Effective lifting capacity is affected by specific conditions, mainly (from priority):
  • Gap between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
  • Angle of force application – highest force is reached only during perpendicular pulling. The force required to slide of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
  • Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of converting into lifting capacity.
  • Metal type – different alloys attracts identically. Alloy additives worsen the attraction effect.
  • Smoothness – ideal contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
  • Temperature – temperature increase causes a temporary drop of force. Check the maximum operating temperature for a given model.

Lifting capacity was determined using a steel plate with a smooth surface of suitable thickness (min. 20 mm), under vertically applied force, whereas under shearing force the holding force is lower. In addition, even a small distance between the magnet and the plate reduces the load capacity.

Safe handling of neodymium magnets
Fire risk

Powder created during grinding of magnets is flammable. Do not drill into magnets unless you are an expert.

Protect data

Equipment safety: Strong magnets can ruin data carriers and sensitive devices (heart implants, hearing aids, mechanical watches).

Shattering risk

Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may shatter into sharp, dangerous pieces.

This is not a toy

These products are not toys. Accidental ingestion of several magnets may result in them pinching intestinal walls, which constitutes a direct threat to life and requires immediate surgery.

Do not overheat magnets

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.

Sensitization to coating

Studies show that the nickel plating (the usual finish) is a common allergen. For allergy sufferers, avoid direct skin contact and opt for encased magnets.

Immense force

Before use, check safety instructions. Sudden snapping can break the magnet or hurt your hand. Think ahead.

Medical interference

Medical warning: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.

Crushing risk

Danger of trauma: The attraction force is so great that it can cause hematomas, crushing, and even bone fractures. Use thick gloves.

Impact on smartphones

Navigation devices and smartphones are extremely sensitive to magnetism. Close proximity with a strong magnet can decalibrate the sensors in your phone.
