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.

Pulling power decreases significantly with every subsequent millimeter of gap. Note that even the smallest gap (e.g., dirt, paint, veneer) significantly diminishes the holding power. Magnetic products operate strongest at the point of direct contact; air break weakens the power. Analyze how quickly the pull force plummet, when the magnet does not touch directly to the metal substrate. When designing the arrangement, discard redundant distances.

This section indicates the approximate shear load needed to initiate the sliding of the magnet downwards on a upright steel plate (assuming standard friction). The holding force depends on the gap size between the magnet and the surface.

When mounting a element on a upright surface (e.g., a fridge), it will only hold only about 20%-30% of nominal attraction strength. Gravity as well as a weak degree of grip mean that products slip faster than they detach. Want to create a hanger? Note that the sliding force is significantly lower than the perpendicular breakaway force. On a smooth steel, the element will slide down under a noticeably lighter cargo. Application of an anti-slip pad can effectively raise the stability.

A too thin steel is incapable of conduct the full magnetic flux, which squanders power of the holder. If you install a neodymium to a too thin substrate, the field will penetrate right through and the attraction force will be weaker. To utilize the maximum of this neodymium's power, you need a suitably thick piece of steel. The saturation phenomenon means that on sheet metal structures (e.g., thin profiles), the product works worse. We suggest choosing the steel dimension 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 attract each other from a wider radius than a magnet and sheet setup. The connection of magnet-to-magnet produces a massive flux and a larger range of action. Designing a solid fastener? Use a pair of magnets instead of one magnet and a steel. Exercise caution that when attracting two neodymiums, the impact force is extreme. The levitation is marginally weaker than the attraction, but still impressive.
*The magnetic induction in repulsion mode is approximately ~0 Gs at the midpoint of the gap (due to field cancellation).
Attention: Figures demonstrate sliding force of dual matching magnets (friction coefficient ~0.15 for Ni-Ni coating).

NdFeB products are prone to chipping – a violent impact against metal can result in shattering. Pay attention to connection velocity – a neodymium left loose speeds with massive force. Kinetic force can destroy the magnet or painful pinches to fingers. Be sure to control the product during installation so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h almost guarantees destruction of the neodymium. Wear safety glasses when working with powerful specimens.

Corrosion 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. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Vertical hold

*Caution: On a vertical wall, the magnet holds just a fraction of its max power.

2. Plate thickness effect

*Thin metal sheet (e.g. computer case) severely reduces the holding force.

3. Power loss vs temp

N52: the maximum material working temperature is 60°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) = 0.22

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 cylindrical magnet, manufactured from durable NdFeB material, which, at dimensions of Ø10x1.5 mm, guarantees maximum efficiency. This specific item features 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. 0.82 kg), this product is available off-the-shelf 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, ensuring 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 high power of 8.04 N with a weight of only 0.88 g, this rod 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 chipping the coating of this professional component. To ensure long-term durability in industry, specialized industrial adhesives are used, which are safe for nickel 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.
This model is characterized by dimensions Ø10x1.5 mm, which, at a weight of 0.88 g, makes it an element with impressive magnetic energy density. The key parameter here is the holding force amounting to approximately 0.82 kg (force ~8.04 N), which, with such defined dimensions, proves the high grade of the NdFeB material. 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 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.

Advantages and disadvantages of neodymium magnets.

Strengths

In addition to their magnetic efficiency, neodymium magnets provide the following advantages:
  • Their strength remains stable, and after around 10 years it drops only by ~1% (theoretically),
  • They feature excellent resistance to weakening of magnetic properties when exposed to external fields,
  • The use of an shiny finish of noble metals (nickel, gold, silver) causes the element to have aesthetics,
  • Magnetic induction on the top side of the magnet remains very high,
  • Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
  • Thanks to freedom in designing and the ability to modify to complex applications,
  • Universal use in electronics industry – they serve a role in data components, electric motors, advanced medical instruments, also multitasking production systems.
  • Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which enables their usage in miniature devices

Weaknesses

Disadvantages of NdFeB magnets:
  • They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also improves its resistance to damage
  • Do not exceed this material temperature limit: 60°C. Overheating may permanently weaken the magnet.
  • Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
  • Limited possibility of making nuts in the magnet and complex forms - preferred is a housing - mounting mechanism.
  • Possible danger related to microscopic parts of magnets pose a threat, in case of ingestion, which gains importance in the context of child safety. Additionally, small components of these products are able to be problematic in diagnostics medical after entering the body.
  • Due to complex production process, their price is higher than average,

Lifting parameters

Optimal lifting capacity of a neodymium magnet – what it depends on?

The declared magnet strength represents the limit force, obtained under ideal test conditions, namely:
  • on a base made of mild steel, perfectly concentrating the magnetic flux
  • with a thickness no less than 10 mm
  • characterized by lack of roughness
  • with zero gap (without coatings)
  • during detachment in a direction perpendicular to the mounting surface
  • at temperature room level

Lifting capacity in practice – influencing factors

Real force impacted by specific conditions, such as (from priority):
  • Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
  • Direction of force – maximum parameter is reached only during perpendicular pulling. The resistance to sliding of the magnet along the plate is typically many times smaller (approx. 1/5 of the lifting capacity).
  • Plate thickness – too thin sheet does not close the flux, causing part of the power to be escaped to the other side.
  • Material composition – different alloys attracts identically. High carbon content worsen the attraction effect.
  • Smoothness – ideal contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
  • Thermal environment – heating the magnet results in weakening of force. It is worth remembering the thermal limit for a given model.

Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under attempts to slide the magnet the holding force is lower. Moreover, even a slight gap between the magnet’s surface and the plate decreases the holding force.

Warnings
This is not a toy

Product intended for adults. Tiny parts pose a choking risk, leading to severe trauma. Store away from kids and pets.

Skin irritation risks

Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If redness occurs, cease handling magnets and use protective gear.

Phone sensors

Navigation devices and mobile phones are extremely sensitive to magnetic fields. Close proximity with a strong magnet can ruin the sensors in your phone.

Flammability

Fire hazard: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this risks ignition.

Conscious usage

Exercise caution. Rare earth magnets attract from a distance and snap with huge force, often faster than you can react.

Health Danger

Warning for patients: Powerful magnets disrupt electronics. Keep minimum 30 cm distance or ask another person to handle the magnets.

Bone fractures

Danger of trauma: The pulling power is so immense that it can cause blood blisters, crushing, and even bone fractures. Use thick gloves.

Power loss in heat

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.

Magnet fragility

Neodymium magnets are sintered ceramics, meaning they are prone to chipping. Impact of two magnets leads to them shattering into small pieces.

Data carriers

Powerful magnetic fields can erase data on payment cards, hard drives, and storage devices. Maintain a gap of at least 10 cm.
