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.

Magnetic force drops significantly with every subsequent millimeter of distance. Remember that even a microscopic distance (e.g., contamination, varnish, dust) significantly reduces the pull force. Neodymiums operate optimally during direct contact; gap kills the power. Observe how quickly the pull force plummet, when the magnet does not touch tightly to the steel surface. When planning the assembly, eliminate unnecessary gaps.

This section presents the estimated shear load necessary to initiate the downward movement of the magnet vertically along a upright steel wall (assuming standard friction coefficient). This value is a function of the gap size between the magnet and the surface.

When mounting a element on a upright wall (e.g., a car body), it you can count on only about 20%-30% of its nominal power. Gravity and a low friction coefficient cause that holders move down faster than they pop off the substrate. Planning a hanger? Note that the sliding force is much weaker than the perpendicular breakaway force. On a painted metal, the element will slide down under a much lighter weight. Application of an anti-slip coating can drastically raise the stability.

A too thin steel is not enough to focus the entire magnetic field, which squanders power of the magnet. If you install a neodymium to a weak sheet, the field will pass right through and the holding will be smaller. To squeeze full efficiency of this neodymium's potential, you require a sufficiently solid element of steel. The material oversaturation means that on sheet metal structures (e.g., car bodies), the magnet shows lower pull force. We suggest choosing the steel dimension according to the table below.

Classic neodymiums irreversibly lose parameters past the thermal threshold. Watch out for overheating – excessive heat can permanently damage this magnet. As the temperature rises, the neodymium's capacity momentarily decreases. Avoid using this magnet near heat sources exceeding its operating temperature limit. Ignoring the limit will cause permanent loss of magnetism.
*Engineering note: Temperature resistance is determined by both grade, as well as the dimension ratios. Low-profile magnets (pancake types) are more susceptible to demagnetization sooner than taller cylinders. The danger warning in the table indicates permanent field degradation for this specific geometry.

Two strong neodymiums interact from a much further distance than a neodymium and metal combination. The connection of two magnets generates a stronger field and a larger range of operation. Designing a solid fastener? Apply two magnets instead of a neodymium and a steel. Be careful that when attracting two neodymiums, the collision energy is extreme. The levitation is marginally weaker than the connection force, but still impressive.
*Field value between like poles is approximately ~0 Gs at the midpoint of the gap (due to field cancellation).
Note: Figures demonstrate shear force of dual same neodymium magnets (friction ~0.15 for Ni-Ni plating).

Powerful magnet radiation is a serious hazard to electronics and medical implants. These magnets produce a field that prevents correct functioning of digital equipment. Notice: the invisible magnetic field penetrates the body and glass. Special caution must be exercised by people with hearing aids and insulin pumps. The risk also applies to: mechanical watches, remotes, speakers, and displays. Do not bring the product near payment cards, HDD media, or sensitive navigation tools.

NdFeB products are very brittle – a collision with steel causes immediate chipping. Pay attention to connection velocity – a magnet released freely speeds with massive force. Kinetic force can destroy the magnet or painful pinches to skin. Be sure to control the product during mounting so it doesn't hit violently against the steel surface. A collision at high speed almost guarantees destruction of the magnet. Wear eye protection when handling with powerful specimens.

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

*Caution: On a vertical wall, the magnet retains just ~20% of its perpendicular strength.

2. Efficiency vs thickness

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

3. Heat tolerance

*For N38 material, the safety limit is 80°C.

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.89

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 a very strong cylinder magnet, composed of durable NdFeB material, which, at dimensions of Ø10x10 mm, guarantees maximum efficiency. The MW 10x10 / N38 model features high dimensional repeatability and professional build quality, making it an ideal solution for the most demanding engineers and designers. As a cylindrical magnet with impressive force (approx. 3.18 kg), this product is in stock from our warehouse in Poland, ensuring rapid order fulfillment. Additionally, 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 Hall effect sensors, and efficient filters, where field concentration on a small surface counts. Thanks to the pull force of 31.19 N with a weight of only 5.89 g, this rod 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., 10.1 mm) using epoxy glues. To ensure long-term durability in industry, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.
Grade N38 is the most frequently chosen standard for professional neodymium magnets, offering a great economic balance and operational stability. If you need the strongest magnets in the same volume (Ø10x10), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.
The presented product is a neodymium magnet with precisely defined parameters: diameter 10 mm and height 10 mm. The key parameter here is the holding force amounting to approximately 3.18 kg (force ~31.19 N), which, with such compact 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 10 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.

Advantages and disadvantages of rare earth magnets.

Benefits

Apart from their notable magnetism, neodymium magnets have these key benefits:
  • They retain full power for around ten years – the loss is just ~1% (according to analyses),
  • They feature excellent resistance to weakening of magnetic properties as a result of opposing magnetic fields,
  • The use of an metallic finish of noble metals (nickel, gold, silver) causes the element to present itself better,
  • Magnetic induction on the working layer of the magnet remains exceptional,
  • Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling functioning at temperatures reaching 230°C and above...
  • Possibility of precise modeling and modifying to concrete requirements,
  • Significant place in innovative solutions – they are used in mass storage devices, electric drive systems, medical equipment, as well as complex engineering applications.
  • Thanks to their power density, small magnets offer high operating force, occupying minimum space,

Cons

Disadvantages of neodymium magnets:
  • To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
  • We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
  • When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
  • Due to limitations in producing nuts and complicated forms in magnets, we propose using a housing - magnetic mechanism.
  • Potential hazard to health – tiny shards of magnets are risky, in case of ingestion, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small elements of these products can disrupt the diagnostic process medical in case of swallowing.
  • Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Lifting parameters

Maximum lifting capacity of the magnet – what contributes to it?

The specified lifting capacity refers to the peak performance, measured under optimal environment, meaning:
  • using a sheet made of mild steel, functioning as a magnetic yoke
  • possessing a massiveness of at least 10 mm to ensure full flux closure
  • characterized by even structure
  • with zero gap (no coatings)
  • under axial force vector (90-degree angle)
  • at temperature room level

Lifting capacity in practice – influencing factors

In real-world applications, the real power results from many variables, presented from most significant:
  • Distance – the presence of foreign body (rust, dirt, air) interrupts the magnetic circuit, which lowers power rapidly (even by 50% at 0.5 mm).
  • Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the maximum value.
  • Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
  • Material composition – different alloys reacts the same. Alloy additives weaken the attraction effect.
  • Surface finish – full contact is possible only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
  • Temperature influence – high temperature reduces pulling force. Too high temperature can permanently damage the magnet.

Lifting capacity was determined with the use of a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under attempts to slide the magnet the load capacity is reduced by as much as fivefold. In addition, even a small distance between the magnet and the plate decreases the lifting capacity.

H&S for magnets
Thermal limits

Watch the temperature. Exposing the magnet above 80 degrees Celsius will ruin its magnetic structure and strength.

Product not for children

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

Life threat

For implant holders: Powerful magnets affect electronics. Keep minimum 30 cm distance or request help to handle the magnets.

Handling rules

Before starting, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.

Risk of cracking

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

Combustion hazard

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

Crushing force

Pinching hazard: The attraction force is so great that it can cause hematomas, crushing, and even bone fractures. Use thick gloves.

Skin irritation risks

Nickel alert: The Ni-Cu-Ni coating contains nickel. If redness appears, cease working with magnets and wear gloves.

GPS Danger

Be aware: rare earth magnets generate a field that confuses precision electronics. Keep a separation from your mobile, device, and GPS.

Cards and drives

Do not bring magnets near a purse, computer, or screen. The magnetic field can irreversibly ruin these devices and wipe information from cards.
