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 drops significantly with every subsequent millimeter of distance. Remember that even a very thin break (e.g., dirt, varnish, dust) noticeably weakens the grip. Magnetic products hold most effectively in perfect adhesion; air break weakens the power. Analyze how quickly the pull force fall, when the product does not touch tightly to the metal substrate. When calculating the arrangement, avoid redundant distances.

This section indicates the estimated weight limit necessary to start the sliding of the magnet down along a vertical steel wall (considering typical friction coefficient). The holding force is a function of the separation distance between the magnet and the surface.

When mounting a element on a vertical wall (e.g., a fridge), it you can count on just about 1/5 of nominal attraction strength. Gravity and a weak degree of grip mean that magnets slip faster than they pull off. Designing a vertical fastening? Note that the sliding force is noticeably lower than the perpendicular breakaway force. On a smooth steel, the magnet will slide down under a noticeably lighter load. Using a rubber pad can drastically improve the result.

A thin metal plate is unable to focus the full magnetic flux, which weakens actual performance of the holder. If you mount a strong magnet to a weak sheet, the magnetism will penetrate right through and the holding will be smaller. To achieve the maximum of this neodymium's power, you require a sufficiently solid element of metal. The saturation effect causes that on thin elements (e.g., thin profiles), the product shows lower pull force. We recommend selecting the steel thickness based on the following data.

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 magnets interact from a much further distance than a magnet and sheet setup. The setup of two magnets creates a more powerful interaction and a further horizon of performance. Want to build a solid fastener? Utilize two neodymiums instead of one magnet and a striker plate. Be careful that when bringing together two magnets, the pinch force is extreme. The levitation is slightly lower than the connection force, but still impressive.
*Field value for N-N configuration is approximately ~0 Gs at the geometric center of the gap (caused by magnetic field nullification).
Important: Figures show shear force of dual same neodymium magnets (friction ~0.15 for Ni-Ni plating).

Magnetic elements are very brittle – a violent impact against metal can result in shattering. Control the attraction moment – a neodymium left loose turns into a projectile. Kinetic force can destroy the magnet or dangerous crushing to skin. Always hold the magnet during bringing near metal so it doesn't hit with great force against the metal. A collision at high speed almost guarantees destruction of the magnet. Wear eye protection when handling with powerful specimens.

1. Vertical hold

*Caution: On a vertical wall, the magnet holds just ~20% of its perpendicular strength.

2. Steel saturation

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

3. Heat tolerance

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.

The offered product is an extremely powerful cylinder magnet, composed of durable NdFeB material, which, at dimensions of Ø10x2 mm, guarantees maximum efficiency. The MW 10x2 zestaw 10 szt. / N38 component features high dimensional repeatability and professional build quality, making it a perfect solution for professional engineers and designers. As a magnetic rod with significant force (approx. 1.27 kg), this product is in stock from our European logistics center, ensuring lightning-fast order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.
It successfully proves itself in modeling, advanced robotics, and broadly understood industry, serving as a fastening or actuating element. Thanks to the pull force of 12.50 N with a weight of only 11.8 g, this cylindrical magnet is indispensable in electronics and wherever low weight is crucial.
Since our magnets have a tolerance of ±0.1mm, 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 automation, specialized industrial adhesives are used, which are safe for nickel 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.
The presented product is a neodymium magnet with precisely defined parameters: diameter 10 mm and height 2 mm. The value of 12.50 N means that the magnet is capable of holding a weight many times exceeding its own mass of 11.8 g. The product has a [NiCuNi] coating, which protects the surface 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 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 diametrically if your project requires it.

Advantages as well as disadvantages of Nd2Fe14B magnets.

Strengths

Besides their tremendous strength, neodymium magnets offer the following advantages:
  • They retain magnetic properties for around ten years – the loss is just ~1% (based on simulations),
  • They have excellent resistance to magnetism drop due to external fields,
  • Thanks to the glossy finish, the coating of nickel, gold-plated, or silver-plated gives an aesthetic appearance,
  • They show high magnetic induction at the operating surface, which affects their effectiveness,
  • Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
  • In view of the ability of precise shaping and customization to individualized needs, magnetic components can be manufactured in a wide range of shapes and sizes, which expands the range of possible applications,
  • Key role in advanced technology sectors – they are used in data components, electromotive mechanisms, advanced medical instruments, and industrial machines.
  • Thanks to concentrated force, small magnets offer high operating force, in miniature format,

Weaknesses

Disadvantages of neodymium magnets:
  • Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a special holder, 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.
  • They rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
  • We suggest cover - magnetic mechanism, due to difficulties in creating threads inside the magnet and complex shapes.
  • Health risk resulting from small fragments of magnets can be dangerous, if swallowed, which is particularly important in the context of child health protection. Furthermore, tiny parts of these devices are able to complicate diagnosis medical after entering the body.
  • High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities

Pull force analysis

Optimal lifting capacity of a neodymium magnet – what contributes to it?

Information about lifting capacity is the result of a measurement for optimal configuration, assuming:
  • using a plate made of mild steel, functioning as a circuit closing element
  • whose thickness is min. 10 mm
  • with an polished touching surface
  • without the slightest insulating layer between the magnet and steel
  • during pulling in a direction perpendicular to the mounting surface
  • at temperature room level

Impact of factors on magnetic holding capacity in practice

In real-world applications, the actual holding force depends on many variables, ranked from crucial:
  • Clearance – existence of any layer (rust, dirt, gap) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
  • Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the maximum value.
  • Substrate thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
  • Material type – ideal substrate is high-permeability steel. Cast iron may generate lower lifting capacity.
  • Surface structure – the more even the plate, the better the adhesion and stronger the hold. Roughness acts like micro-gaps.
  • Thermal environment – temperature increase causes a temporary drop of force. Check the maximum operating temperature for a given model.

Lifting capacity was determined with the use of a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under shearing force the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.

Precautions when working with NdFeB magnets
Product not for children

These products are not intended for children. Accidental ingestion of multiple magnets may result in them connecting inside the digestive tract, which poses a direct threat to life and necessitates urgent medical intervention.

Magnetic media

Do not bring magnets near a wallet, computer, or TV. The magnetic field can permanently damage these devices and wipe information from cards.

Hand protection

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

Threat to navigation

A strong magnetic field disrupts the functioning of compasses in phones and GPS navigation. Maintain magnets near a smartphone to prevent damaging the sensors.

Conscious usage

Be careful. Neodymium magnets attract from a distance and connect with huge force, often faster than you can move away.

Warning for allergy sufferers

Studies show that the nickel plating (standard magnet coating) is a common allergen. If your skin reacts to metals, refrain from direct skin contact and choose versions in plastic housing.

Do not drill into magnets

Fire warning: Rare earth powder is explosive. Avoid machining magnets in home conditions as this risks ignition.

Danger to pacemakers

People with a ICD have to keep an safe separation from magnets. The magnetism can interfere with the operation of the implant.

Magnets are brittle

Watch out for shards. Magnets can explode upon violent connection, ejecting shards into the air. We recommend safety glasses.

Heat sensitivity

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.
