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 per each millimeter of distance. Remember that even the smallest gap (e.g., dirt, varnish, dust) noticeably diminishes the holding power. Neodymiums work most effectively during direct contact; distance nullifies the power. Analyze how quickly the load capacity fall, when the product does not touch tightly to the metal substrate. When designing the mounting, avoid unnecessary gaps.

This section defines the estimated holding capacity required to start the sliding of the magnet downwards on a upright metal surface (assuming standard friction coefficient). The holding force varies with the air gap between the magnet and the surface.

When hanging a magnet on a upright plane (e.g., a fridge), it will maintain only about 20%-30% of nominal attraction strength. Gravity and a weak degree of grip influence the fact that holders move down faster than they detach. Planning a vertical fastening? Note that the shear force is significantly lower than the maximum static pull force. On a painted metal, the holder will slip down under a much lighter cargo. Using a rubber pad can drastically increase the grip.

A thin metal plate is incapable of take in the full magnetic flux, which squanders power of the holder. If you install a neodymium to a too thin substrate, the field will pass right through and the attraction force will be weaker. To squeeze full efficiency of this neodymium's power, you need a suitably thick backing of metal. The saturation phenomenon means that on sheet metal structures (e.g., appliance housings), the magnet 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 magnetic products interact from a wider radius than a magnet and steel combination. The setup of two magnets produces a massive flux and a wider radius of performance. Designing a solid fastener? Utilize two neodymiums instead of one magnet and a steel. Be careful that when attracting two neodymiums, the impact force is massive. The levitation is marginally weaker than the connection force, but still significant.
*The magnetic induction for N-N configuration reaches ~0 Gs at the midpoint of the gap (resulting from vector opposition).
* Figures refer to sliding force of dual identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

Magnetic elements are very brittle – a collision with steel risks their cracking. Pay attention to connection velocity – a neodymium left loose turns into a projectile. Striking energy can destroy the magnet or dangerous crushing to skin. Hold the magnet firmly during installation so it doesn't slam with momentum against the metal. A contact at a velocity of dozens of km/h ends with a crack of the magnet. Wear safety glasses when working with large magnets.

1. Shear force

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

2. Steel thickness impact

*Thin steel (e.g. 0.5mm PC case) severely 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) = 0.59

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 a very strong rod magnet, composed of durable NdFeB material, which, with dimensions of Ø6x3 mm, guarantees maximum efficiency. This specific item 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. 1.15 kg), this product is in stock from our European logistics center, ensuring rapid order fulfillment. Additionally, its Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.
This model is created for building electric motors, advanced Hall effect sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the high power of 11.23 N with a weight of only 6.4 g, this cylindrical magnet is indispensable in electronics and wherever every gram matters.
Since our magnets have a tolerance of ±0.1mm, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 6.1 mm) using epoxy glues. To ensure long-term durability in automation, 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.
The presented product is a neodymium magnet with precisely defined parameters: diameter 6 mm and height 3 mm. The value of 11.23 N means that the magnet is capable of holding a weight many times exceeding its own mass of 6.4 g. The product has a [NiCuNi] coating, which protects the surface against external factors, giving it an aesthetic, silvery shine.
This cylinder is magnetized axially (along the height of 3 mm), which means that the N and S poles are located on the flat, circular surfaces. Thanks to this, the magnet can be easily glued into a hole and achieve a strong field on the front surface. On request, we can also produce versions magnetized diametrically if your project requires it.

Strengths and weaknesses of neodymium magnets.

Pros

Besides their tremendous pulling force, neodymium magnets offer the following advantages:
  • They do not lose magnetism, even during around ten years – the drop in strength is only ~1% (according to tests),
  • Magnets effectively defend themselves against loss of magnetization caused by external fields,
  • Thanks to the shimmering finish, the surface of Ni-Cu-Ni, gold-plated, or silver-plated gives an elegant appearance,
  • Magnets have maximum magnetic induction on the active area,
  • Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
  • Thanks to freedom in shaping and the ability to adapt to individual projects,
  • Versatile presence in future technologies – they find application in computer drives, drive modules, medical equipment, and multitasking production systems.
  • Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Limitations

Disadvantages of NdFeB magnets:
  • To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
  • Do not exceed this material temperature limit: 80°C. Overheating may permanently weaken the magnet.
  • When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
  • We suggest cover - magnetic holder, due to difficulties in creating nuts inside the magnet and complex forms.
  • Potential hazard to health – tiny shards of magnets can be dangerous, in case of ingestion, which becomes key in the context of child safety. Additionally, tiny parts of these products are able to complicate diagnosis medical when they are in the body.
  • High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities

Lifting parameters

Magnetic strength at its maximum – what affects it?

The force parameter is a theoretical maximum value conducted under specific, ideal conditions:
  • using a base made of high-permeability steel, acting as a magnetic yoke
  • with a thickness minimum 10 mm
  • with a surface perfectly flat
  • without the slightest air gap between the magnet and steel
  • during pulling in a direction vertical to the plane
  • at room temperature

Key elements affecting lifting force

Effective lifting capacity is affected by specific conditions, including (from most important):
  • Distance – existence of any layer (rust, dirt, gap) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
  • Load vector – maximum parameter is reached only during perpendicular pulling. The shear force of the magnet along the plate is typically many times smaller (approx. 1/5 of the lifting capacity).
  • Steel thickness – insufficiently thick sheet does not accept the full field, causing part of the power to be escaped to the other side.
  • Chemical composition of the base – mild steel gives the best results. Alloy admixtures lower magnetic permeability and holding force.
  • Plate texture – smooth surfaces guarantee perfect abutment, which increases force. Uneven metal weaken the grip.
  • Temperature influence – hot environment reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.

Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under parallel forces the load capacity is reduced by as much as 5 times. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the load capacity.

H&S for magnets
Avoid contact if allergic

Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If an allergic reaction occurs, cease handling magnets and wear gloves.

Medical interference

Medical warning: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.

Fire risk

Combustion risk: Rare earth powder is explosive. Do not process magnets in home conditions as this risks ignition.

Crushing risk

Pinching hazard: The attraction force is so immense that it can cause hematomas, pinching, and broken bones. Use thick gloves.

Handling rules

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

Neodymium magnets are not toys. Eating several magnets can lead to them attracting across intestines, which poses a critical condition and necessitates urgent medical intervention.

Keep away from computers

Intense magnetic fields can corrupt files on payment cards, hard drives, and storage devices. Maintain a gap of min. 10 cm.

Compass and GPS

Navigation devices and smartphones are extremely sensitive to magnetic fields. Direct contact with a powerful NdFeB magnet can decalibrate the sensors in your phone.

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.

Protective goggles

Watch out for shards. Magnets can explode upon violent connection, launching shards into the air. Eye protection is mandatory.
