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 drastically with every subsequent millimeter of distance. Note that even a microscopic distance (e.g., dirt, varnish, dust) noticeably diminishes the holding power. Neodymiums hold strongest in perfect adhesion; gap kills the force. Analyze how quickly the load capacity fall, when the product does not touch flatly to the metal substrate. When planning the assembly, avoid redundant distances.

The table below presents the theoretical holding capacity needed to start the shifting of the magnet down along a vertical metal surface (assuming typical friction). The holding force depends on the distance between the magnet and the surface.

When hanging a holder on a vertical surface (e.g., a car body), it will only hold only about 20%-30% of its maximum pull force. Gravity and a weak degree of grip cause that products move down faster than they pull off. Planning a vertical fastening? Note that the sliding force is noticeably lower than the maximum static pull force. On a slippery surface, the element will slide down under a significantly smaller cargo. Using a rubber layer can effectively improve the result.

A thin metal plate is not enough to focus the full magnetic flux, which squanders power of the holder. If you mount a strong magnet to a too thin substrate, the magnetism will penetrate right through and the attraction force will be weaker. To squeeze the maximum of this magnet's power, you need a suitably thick backing of metal. The material oversaturation causes that on sheet metal structures (e.g., appliance housings), the product works worse. 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 interact from a wider radius than a magnet and sheet setup. The connection of magnet-to-magnet creates a more powerful interaction and a further horizon of operation. Planning to create a strong closure? Use a pair of magnets instead of a neodymium and a steel. Be careful that when bringing together two magnets, the pinch force is massive. The levitation is a bit weaker than the connection force, but still impressive.
*The magnetic induction for N-N configuration reaches ~0 Gs at the midpoint of the gap (resulting from vector opposition).
Attention: Estimates apply to friction force of dual identical magnets (friction coefficient ~0.15 for Ni-Ni coating).

Neodymium magnets are prone to chipping – a collision with steel can result in shattering. Control the attraction moment – a magnet released freely turns into a projectile. Impact energy can destroy the magnet or dangerous crushing to skin. Be sure to control the product during bringing near metal so it doesn't slam with momentum against the metal. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Use safety goggles when handling with powerful specimens.

Contrary to myths, water does not block the magnetic field. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Vertical hold

*Note: On a vertical wall, the magnet retains just a fraction of its nominal pull.

2. Efficiency vs thickness

*Thin steel (e.g. 0.5mm PC case) severely weakens the holding force.

3. Temperature resistance

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) = 0.25

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 a very strong rod magnet, composed of durable NdFeB material, which, with dimensions of Ø7x1.2 mm, guarantees maximum efficiency. This specific item features high dimensional repeatability and professional build quality, making it a perfect solution for the most demanding engineers and designers. As a cylindrical magnet with impressive force (approx. 0.49 kg), this product is in stock from our warehouse in Poland, ensuring rapid order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.
This model is perfect for building electric motors, advanced sensors, and efficient magnetic separators, where maximum induction on a small surface counts. Thanks to the pull force of 4.81 N with a weight of only 0.35 g, this rod is indispensable in electronics and wherever low weight is crucial.
Due to the delicate structure of the ceramic sinter, we absolutely advise against force-fitting (so-called press-fit), as this risks chipping the coating of this professional component. To ensure stability 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 7 mm and height 1.2 mm. The value of 4.81 N means that the magnet is capable of holding a weight many times exceeding its own mass of 0.35 g. The product has a [NiCuNi] coating, which secures it 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 7 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 neodymium magnets.

Strengths

Besides their tremendous strength, neodymium magnets offer the following advantages:
  • Their strength is durable, and after approximately ten years it decreases only by ~1% (theoretically),
  • Neodymium magnets prove to be highly resistant to loss of magnetic properties caused by external interference,
  • In other words, due to the shiny layer of silver, the element looks attractive,
  • Magnetic induction on the working part of the magnet remains strong,
  • Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
  • Thanks to versatility in constructing and the ability to adapt to client solutions,
  • Key role in electronics industry – they are used in HDD drives, motor assemblies, advanced medical instruments, also other advanced devices.
  • Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which makes them useful in compact constructions

Cons

Disadvantages of NdFeB magnets:
  • At very strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's 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 suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
  • Due to limitations in realizing threads and complicated shapes in magnets, we propose using casing - magnetic holder.
  • Possible danger resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child safety. It is also worth noting that small components 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 economically unviable,

Lifting parameters

Highest magnetic holding force – what it depends on?

Breakaway force was defined for the most favorable conditions, assuming:
  • on a plate made of structural steel, perfectly concentrating the magnetic field
  • possessing a thickness of at least 10 mm to avoid saturation
  • characterized by smoothness
  • without the slightest air gap between the magnet and steel
  • for force applied at a right angle (pull-off, not shear)
  • at standard ambient temperature

Key elements affecting lifting force

It is worth knowing that the application force may be lower subject to the following factors, in order of importance:
  • Gap between surfaces – every millimeter of distance (caused e.g. by veneer or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
  • Angle of force application – highest force is available only during perpendicular pulling. The shear force of the magnet along the surface is usually many times lower (approx. 1/5 of the lifting capacity).
  • Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
  • Material type – the best choice is high-permeability steel. Stainless steels may have worse magnetic properties.
  • Surface structure – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Roughness creates an air distance.
  • Temperature – temperature increase results in weakening of induction. 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 a perpendicular force was applied, in contrast under parallel forces the lifting capacity is smaller. Moreover, even a slight gap between the magnet’s surface and the plate decreases the holding force.

Safety rules for work with neodymium magnets
ICD Warning

People with a heart stimulator should keep an absolute distance from magnets. The magnetic field can disrupt the operation of the implant.

Compass and GPS

Remember: rare earth magnets generate a field that confuses precision electronics. Maintain a safe distance from your mobile, tablet, and navigation systems.

Keep away from computers

Equipment safety: Strong magnets can damage data carriers and sensitive devices (pacemakers, medical aids, timepieces).

Heat warning

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.

Product not for children

Always keep magnets away from children. Ingestion danger is high, and the consequences of magnets clamping inside the body are fatal.

Material brittleness

Beware of splinters. Magnets can fracture upon violent connection, launching shards into the air. Eye protection is mandatory.

Serious injuries

Pinching hazard: The attraction force is so immense that it can cause blood blisters, pinching, and even bone fractures. Protective gloves are recommended.

Dust is flammable

Dust produced during cutting of magnets is combustible. Avoid drilling into magnets unless you are an expert.

Sensitization to coating

Studies show that nickel (the usual finish) is a strong allergen. If your skin reacts to metals, prevent direct skin contact or select encased magnets.

Handling guide

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