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.

1. Vertical hold

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

2. Steel thickness impact

*Thin steel (e.g. 0.5mm PC case) significantly reduces 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) = 0.50

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.

This product is an incredibly powerful cylinder magnet, composed of advanced NdFeB material, which, with dimensions of Ø5x2 mm, guarantees maximum efficiency. The MW 5x2 zestaw 200 szt. / N38 model features a tolerance of ±0.1mm and professional build quality, making it an excellent solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 0.70 kg), this product is in stock from our European logistics center, ensuring lightning-fast order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.
It successfully proves itself in DIY projects, advanced robotics, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 6.86 N with a weight of only 58 g, this rod is indispensable in miniature devices and wherever every gram matters.
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 automation, specialized industrial adhesives are used, which do not react with the nickel coating 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 Ø5x2 mm, which, at a weight of 58 g, makes it an element with high magnetic energy density. The value of 6.86 N means that the magnet is capable of holding a weight many times exceeding its own mass of 58 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 2 mm), which means that the N and S poles are located on the flat, circular surfaces. 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.

Strengths as well as weaknesses of rare earth magnets.

Pros

In addition to their pulling strength, neodymium magnets provide the following advantages:
  • They do not lose strength, even during approximately 10 years – the decrease in power is only ~1% (theoretically),
  • Magnets effectively defend themselves against loss of magnetization caused by ambient magnetic noise,
  • By using a shiny coating of nickel, the element acquires an elegant look,
  • The surface of neodymium magnets generates a powerful magnetic field – this is a distinguishing feature,
  • Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
  • Thanks to versatility in constructing and the ability to modify to client solutions,
  • Versatile presence in electronics industry – they are used in computer drives, brushless drives, advanced medical instruments, and modern systems.
  • Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Disadvantages

Disadvantages of neodymium magnets:
  • At strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's 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 advise using waterproof magnets e.g. in rubber, plastic
  • Limited possibility of making nuts in the magnet and complex forms - preferred is a housing - magnet mounting.
  • Health risk related to microscopic parts of magnets pose a threat, if swallowed, which is particularly important in the context of child safety. It is also worth noting that tiny parts of these devices can disrupt the diagnostic process medical when they are in the body.
  • With large orders the cost of neodymium magnets can be a barrier,

Lifting parameters

Highest magnetic holding force – what affects it?

Breakaway force was determined for ideal contact conditions, assuming:
  • with the application of a sheet made of special test steel, ensuring maximum field concentration
  • possessing a thickness of minimum 10 mm to avoid saturation
  • with an ground touching surface
  • with direct contact (no paint)
  • during detachment in a direction vertical to the plane
  • in neutral thermal conditions

Lifting capacity in real conditions – factors

In real-world applications, the actual lifting capacity results from several key aspects, presented from most significant:
  • Distance (betwixt the magnet and the plate), since even a tiny distance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
  • Force direction – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet holds much less (typically approx. 20-30% of maximum force).
  • Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
  • Steel type – mild steel gives the best results. Alloy steels reduce magnetic permeability and holding force.
  • Base smoothness – the more even the surface, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
  • Thermal conditions – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).

Lifting capacity was assessed using a steel plate with a smooth surface of optimal thickness (min. 20 mm), under vertically applied force, in contrast under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Additionally, even a minimal clearance between the magnet and the plate decreases the holding force.

Warnings
Precision electronics

Note: neodymium magnets produce a field that disrupts sensitive sensors. Keep a separation from your phone, device, and navigation systems.

Warning for heart patients

For implant holders: Strong magnetic fields disrupt electronics. Maintain minimum 30 cm distance or ask another person to handle the magnets.

Operating 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.

Shattering risk

Protect your eyes. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. Eye protection is mandatory.

Choking Hazard

Adult use only. Tiny parts can be swallowed, causing severe trauma. Keep away from children and animals.

Allergic reactions

Allergy Notice: The Ni-Cu-Ni coating contains nickel. If an allergic reaction happens, cease working with magnets and wear gloves.

Serious injuries

Large magnets can smash fingers in a fraction of a second. Do not place your hand between two strong magnets.

Conscious usage

Before use, read the rules. Sudden snapping can break the magnet or injure your hand. Be predictive.

Do not drill into magnets

Dust produced during grinding of magnets is flammable. Do not drill into magnets unless you are an expert.

Threat to electronics

Equipment safety: Neodymium magnets can ruin data carriers and delicate electronics (heart implants, hearing aids, timepieces).
