Frequently asked questions

What is the maximum working temperature of a disc magnet?
Standard N-series grades work up to 80 °C. Grades N50, N52 and N54 have a lower limit of 60 °C, because coercivity falls as BHmax rises. Higher temperatures require the H (120 °C), SH (150 °C), UH (180 °C), EH (200 °C) or AH (230 °C) series. Within the working range the magnet loses about 0.11% of its induction per degree, and that loss is reversible.
What is the difference between N38, N42 and N52?
The number after N is the energy product BHmax. Moving from N38 to N52 raises it by several tens of percent, but the real holding force increases by roughly 20%, because force also depends on geometry and on the magnetic circuit. N52 costs about twice as much as N42, so for most mounting work N38–N42 is the best price-to-force ratio.
What is the dimensional tolerance?
±0.1 mm as standard, ±0.05 mm to order. The tolerance is stated next to the dimensions on every product page.

Pulling power drops sharply with every subsequent millimeter of gap. Remember that even a very thin break (e.g., contamination, paint, dust) noticeably reduces the pull force. Magnets operate optimally at the point of direct contact; gap nullifies the power. Notice how flashily the load capacity plummet, when the product does not adhere tightly to the steel surface. When designing the assembly, discard unnecessary gaps.

The table below shows the theoretical weight limit needed to cause the slippage of the magnet vertically against a upright metal surface (assuming standard friction coefficient). This value depends on the distance between the magnet and the metal.

When placing a magnet on a upright wall (e.g., a car body), it you can count on only approx. 20%-30% of nominal attraction strength. Gravitational force as well as a low friction coefficient influence the fact that magnets slide down easier than they detach. Planning a wall mount? Remember that the sliding force is significantly lower than the maximum static pull force. On a smooth steel, the holder will give way down under a noticeably lighter load. Application of an anti-slip layer can drastically raise the stability.

A thin sheet is not enough to absorb the entire magnetic field, which weakens actual performance of the magnet. Should you mount a strong magnet to a too thin substrate, the magnetism will pass right through and the pull force will drop sharply. To achieve 100% of this magnet's potential, you need a suitably thick element of metal. The saturation phenomenon means that on thin elements (e.g., thin profiles), the magnet works worse. We suggest choosing the steel dimension according to the table below.

Standard neodymium magnets change their properties power after exceeding the maximum temperature. Watch out for overheating – excessive heat can permanently demagnetize this product. With every degree above norm, the neodymium's force briefly drops. Refrain from using this product close to ovens exceeding its working range. Exceeding the critical threshold will cause permanent loss of magnetism.
*Technical advisory: Heat tolerance depends not only on the material grade, as well as the dimension ratios. Thin magnets (low Pc) risk losing magnetic properties under lower heat stress than long magnets. Red status in the table signals a risk of irreversible loss for this particular item.

Two strong neodymiums attract each other from a significantly greater distance than a magnet and steel combination. The setup of two magnets generates a stronger field and a further horizon of operation. Designing a solid fastener? Apply two magnets instead of a neodymium and a steel. Remember that when connecting a pair of magnets, the pinch force is huge. The repulsion force is a bit weaker than the attraction, but still large.
*Flux density between like poles is approximately ~0 Gs at the geometric center between the magnets (due to field cancellation).
Note: Estimates apply to friction force of two identical magnets (friction ~0.15 for Ni-Ni layer).

Powerful magnet radiation is a large risk to electronic devices as well as medical implants. These neodymiums produce a field that prevents correct functioning of digital equipment. Be aware: the invisible magnetic field penetrates the body and glass. Increased vigilance must be exercised by people with hearing aids and insulin pumps. The risk also applies to: automatic timepieces, remotes, membranes, and displays. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Magnetic elements are prone to chipping – a collision with steel causes immediate chipping. Pay attention to connection velocity – a neodymium left loose speeds with massive force. Impact energy can cause material chips or dangerous crushing to fingers. Hold the magnet firmly during mounting so it doesn't hit with great force against the steel surface. A contact at a velocity of dozens of km/h means shattering of the neodymium. Use safety goggles when working with powerful specimens.

Rust risk: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!
In water, the magnet feels stronger thanks to Archimedes' principle. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Shear force

*Caution: On a vertical surface, the magnet retains merely approx. 20-30% of its nominal pull.

2. Plate thickness effect

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

3. Heat tolerance

*For N38 grade, the critical limit is 80°C.

4. Demagnetization curve and operating point (B-H)

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.85

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.

The offered product is an incredibly powerful rod magnet, composed of modern NdFeB material, which, with dimensions of Ø33x30 mm, guarantees the highest energy density. The MW 33x30 / N38 component is characterized by high dimensional repeatability and professional build quality, making it a perfect solution for the most demanding engineers and designers. As a cylindrical magnet with significant force (approx. 35.84 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring quick order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.
This model is ideal for building electric motors, advanced sensors, and efficient magnetic separators, where maximum induction on a small surface counts. Thanks to the pull force of 351.54 N with a weight of only 192.44 g, this cylindrical magnet is indispensable in electronics and wherever every gram matters.
Due to the delicate structure of the ceramic sinter, we absolutely advise against force-fitting (so-called press-fit), as this risks immediate cracking of this precision component. To ensure stability in industry, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.
Magnets NdFeB grade N38 are suitable for the majority of applications in modeling and machine building, where extreme miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø33x30), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.
This model is characterized by dimensions Ø33x30 mm, which, at a weight of 192.44 g, makes it an element with impressive magnetic energy density. The key parameter here is the lifting capacity amounting to approximately 35.84 kg (force ~351.54 N), which, with such defined dimensions, proves the high power of the NdFeB material. The product has a [NiCuNi] coating, which secures it against external factors, giving it an aesthetic, silvery shine.
This rod magnet is magnetized axially (along the height of 30 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.

Advantages

Apart from their notable magnetism, neodymium magnets have these key benefits:
  • They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (based on calculations),
  • They possess excellent resistance to weakening of magnetic properties when exposed to opposing magnetic fields,
  • By applying a lustrous coating of silver, the element has an professional look,
  • The surface of neodymium magnets generates a strong magnetic field – this is one of their assets,
  • Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
  • Thanks to flexibility in shaping and the capacity to modify to unusual requirements,
  • Universal use in electronics industry – they are utilized in data components, electric motors, precision medical tools, and multitasking production systems.
  • Thanks to their power density, small magnets offer high operating force, with minimal size,

Limitations

Disadvantages of neodymium magnets:
  • At strong impacts they can break, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
  • Neodymium magnets lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
  • Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
  • Limited ability of creating nuts in the magnet and complicated forms - preferred is casing - magnetic holder.
  • Possible danger to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small elements of these devices can complicate diagnosis medical after entering the body.
  • High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities

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

The specified lifting capacity refers to the limit force, recorded under laboratory conditions, specifically:
  • with the use of a sheet made of low-carbon steel, guaranteeing full magnetic saturation
  • possessing a massiveness of min. 10 mm to avoid saturation
  • with a plane cleaned and smooth
  • with zero gap (no paint)
  • for force acting at a right angle (in the magnet axis)
  • at ambient temperature approx. 20 degrees Celsius

Practical aspects of lifting capacity – factors

It is worth knowing that the working load will differ influenced by elements below, starting with the most relevant:
  • Gap (between the magnet and the plate), because even a very small clearance (e.g. 0.5 mm) results in a reduction in force by up to 50% (this also applies to varnish, corrosion or dirt).
  • Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
  • Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
  • Plate material – mild steel gives the best results. Higher carbon content decrease magnetic permeability and lifting capacity.
  • Surface condition – ground elements guarantee perfect abutment, which increases force. Uneven metal weaken the grip.
  • Temperature influence – high temperature weakens pulling force. Too high temperature can permanently damage the magnet.

Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under shearing force the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet and the plate decreases the lifting capacity.

Warnings
Protect data

Avoid bringing magnets close to a purse, computer, or screen. The magnetic field can destroy these devices and erase data from cards.

Do not drill into magnets

Dust generated during machining of magnets is self-igniting. Do not drill into magnets unless you are an expert.

Powerful field

Before starting, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Be predictive.

GPS and phone interference

Be aware: rare earth magnets generate a field that disrupts sensitive sensors. Maintain a separation from your mobile, tablet, and GPS.

Permanent damage

Regular neodymium magnets (grade N) lose power when the temperature goes above 80°C. The loss of strength is permanent.

Bodily injuries

Mind your fingers. Two large magnets will snap together immediately with a force of massive weight, crushing anything in their path. Be careful!

Beware of splinters

Beware of splinters. Magnets can fracture upon violent connection, launching shards into the air. Wear goggles.

Warning for heart patients

For implant holders: Powerful magnets disrupt medical devices. Maintain minimum 30 cm distance or request help to handle the magnets.

Nickel allergy

It is widely known that nickel (the usual finish) is a common allergen. For allergy sufferers, prevent touching magnets with bare hands or choose versions in plastic housing.

Swallowing risk

Always store magnets away from children. Ingestion danger is significant, and the consequences of magnets connecting inside the body are life-threatening.
