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.

Corrosion warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

1. Sliding resistance

*Warning: On a vertical surface, the magnet holds merely approx. 20-30% of its perpendicular strength.

2. Efficiency vs thickness

*Thin steel (e.g. 0.5mm PC case) severely limits 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) = 0.19

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. 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.

Other deals

The presented product is an exceptionally strong cylindrical magnet, made from advanced NdFeB material, which, with dimensions of Ø12x1.5 mm, guarantees maximum efficiency. The MW 12x1.5 zestaw 1820 szt. / N38 component boasts an accuracy of ±0.1mm and industrial build quality, making it an excellent solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 0.87 kg), this product is in stock from our European logistics center, ensuring rapid order fulfillment. Additionally, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, guaranteeing 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 pull force of 8.51 N with a weight of only 2311.4 g, this rod is indispensable in miniature devices 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., 12.1 mm) using epoxy glues. To ensure stability in industry, anaerobic resins 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.
The presented product is a neodymium magnet with precisely defined parameters: diameter 12 mm and height 1.5 mm. The key parameter here is the lifting capacity amounting to approximately 0.87 kg (force ~8.51 N), which, with such defined dimensions, proves the high power of the NdFeB material. The product has a [NiCuNi] coating, which protects the surface against external factors, giving it an aesthetic, silvery shine.
This rod magnet is magnetized axially (along the height of 1.5 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 through the diameter if your project requires it.

Advantages and disadvantages of rare earth magnets.

Strengths

Besides their stability, neodymium magnets are valued for these benefits:
  • Their magnetic field remains stable, and after around 10 years it decreases only by ~1% (according to research),
  • They maintain their magnetic properties even under strong external field,
  • In other words, due to the glossy finish of silver, the element becomes visually attractive,
  • They feature high magnetic induction at the operating surface, which affects their effectiveness,
  • Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling operation at temperatures approaching 230°C and above...
  • Due to the potential of flexible shaping and adaptation to unique requirements, magnetic components can be created in a variety of geometric configurations, which increases their versatility,
  • Huge importance in future technologies – they find application in computer drives, electric drive systems, medical equipment, and technologically advanced constructions.
  • Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Limitations

Disadvantages of NdFeB magnets:
  • 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.
  • They rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
  • Limited possibility of making threads in the magnet and complex shapes - recommended is casing - magnetic holder.
  • Health risk related to microscopic parts of magnets pose a threat, if swallowed, which gains importance in the context of child safety. It is also worth noting that small elements of these magnets can be problematic in diagnostics medical when they are in the body.
  • Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Pull force analysis

Detachment force of the magnet in optimal conditions – what affects it?

Breakaway force was defined for ideal contact conditions, taking into account:
  • with the contact of a sheet made of low-carbon steel, ensuring maximum field concentration
  • with a cross-section minimum 10 mm
  • with an ground contact surface
  • with zero gap (no impurities)
  • under perpendicular force vector (90-degree angle)
  • at ambient temperature approx. 20 degrees Celsius

Impact of factors on magnetic holding capacity in practice

In real-world applications, the actual lifting capacity depends on several key aspects, ranked from the most important:
  • Distance (between the magnet and the plate), as even a very small clearance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to varnish, rust or dirt).
  • Force direction – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
  • Base massiveness – insufficiently thick steel does not close the flux, causing part of the flux to be wasted to the other side.
  • Material composition – not every steel reacts the same. High carbon content weaken the attraction effect.
  • Surface quality – the more even the surface, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
  • Temperature influence – hot environment weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity was determined using a polished steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under parallel forces the holding force is lower. Additionally, even a small distance between the magnet and the plate reduces the holding force.

Safety rules for work with neodymium magnets
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.

Magnetic media

Do not bring magnets near a wallet, laptop, or screen. The magnetism can destroy these devices and wipe information from cards.

Mechanical processing

Machining of neodymium magnets poses a fire hazard. Magnetic powder reacts violently with oxygen and is hard to extinguish.

Conscious usage

Before use, read the rules. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.

Physical harm

Mind your fingers. Two large magnets will join immediately with a force of massive weight, destroying everything in their path. Be careful!

Pacemakers

Patients with a pacemaker must maintain an absolute distance from magnets. The magnetism can interfere with the functioning of the implant.

Fragile material

Despite metallic appearance, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.

Phone sensors

An intense magnetic field negatively affects the functioning of magnetometers in smartphones and navigation systems. Maintain magnets close to a device to avoid breaking the sensors.

Swallowing risk

These products are not suitable for play. Swallowing a few magnets can lead to them connecting inside the digestive tract, which poses a severe health hazard and requires urgent medical intervention.

Sensitization to coating

Medical facts indicate that the nickel plating (the usual finish) is a common allergen. If you have an allergy, avoid direct skin contact or opt for coated magnets.
