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 weakens significantly per each millimeter of distance. Note that even the smallest gap (e.g., dirt, paint, rust) significantly reduces the pull force. Magnets hold optimally at the point of direct contact; distance kills the force. Analyze how flashily the load capacity plummet, when the product does not adhere tightly to the steel surface. When designing the arrangement, discard additional spacers.

When mounting a element on a vertical surface (e.g., a board), it you can count on just approx. 1/5 of its nominal power. Gravity as well as a low friction coefficient influence the fact that holders slide down easier than they detach. Designing a hanger? Note that the shear force is significantly lower than the maximum static pull force. On a smooth steel, the element will give way down under a significantly smaller load. Utilizing a rubberized coating can drastically improve the result.

A thin sheet cannot conduct the entire magnetic field, which weakens actual performance of the holder. Should you attach a powerful product to a weak sheet, the magnetism will pass right through and the holding will be smaller. To squeeze 100% of this neodymium's power, you require a sufficiently solid element of metal. The material oversaturation causes that on thin elements (e.g., appliance housings), the product holds weaker. We advise picking the steel cross-section from these parameters.

Classic neodymiums irreversibly lose power above the temperature limit. Protect against heat – excessive heat can irreversibly destroy this product. As the temperature rises, the magnet's capacity briefly decreases. Refrain from using this product in hot environments higher than its safe range. Ignoring the limit will cause permanent loss of magnetic properties.
*Engineering note: Heat tolerance depends not only on the material grade, as well as the dimension ratios. Thin magnets (pancake types) are more susceptible to demagnetization sooner than long magnets. The danger warning in the table points to a risk of irreversible loss for this particular item.

Two magnetic products attract each other from a significantly greater distance than a magnet and steel combination. Such a system of magnet-to-magnet produces a massive flux and a larger range of action. Designing a strong closure? Utilize two neodymiums instead of a neodymium and a striker plate. Exercise caution that when connecting a pair of magnets, the impact force is huge. The levitation is a bit weaker than the attraction, but still large.
*Flux density for N-N configuration reaches ~0 Gs at the geometric center of the gap (resulting from vector opposition).
Note: Results apply to shear force of dual identical magnets (friction ~0.15 for Ni-Ni coating).

Powerful magnet radiation poses a real danger to electronics and medical implants. These neodymiums generate a flux that prevents correct functioning of digital equipment. Remember: the invisible magnetic field acts through matter and plastic. Special caution must be taken by people with cochlear implants and drug dispensers. Also at risk are: automatic timepieces, car keys, membranes, and screens. Do not bring the product near payment cards, hard drives, or sensitive navigation tools.

Magnetic elements are very brittle – a strong collision with metal can result in shattering. Watch the impact speed – a magnet released freely becomes dangerous. Impact energy can cause material chips or injury to skin. Always hold the magnet during mounting so it doesn't hit violently against the metal. A contact at a velocity of dozens of km/h ends with a crack of the neodymium. Wear eye protection when working with large magnets.

Contrary to myths, water does not block the magnetic field. However, remember the water resistance when pulling the rope quickly.

1. Vertical hold

*Note: On a vertical surface, the magnet holds just ~20% of its perpendicular strength.

2. Steel saturation

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

3. Temperature resistance

*For standard magnets, the safety limit is 80°C.

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.44

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 presented product is an exceptionally strong cylinder magnet, made from durable NdFeB material, which, with dimensions of Ø45x15 mm, guarantees optimal power. The MW 45x15 / N38 component features an accuracy of ±0.1mm and industrial build quality, making it a perfect solution for professional engineers and designers. As a magnetic rod with significant force (approx. 48.55 kg), this product is in stock from our warehouse in Poland, ensuring rapid order fulfillment. Additionally, its Ni-Cu-Ni coating effectively protects it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.
This model is perfect for building generators, advanced sensors, and efficient magnetic separators, where maximum induction on a small surface counts. Thanks to the pull force of 476.32 N with a weight of only 178.92 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 chipping the coating of this precision component. To ensure stability in industry, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.
Grade N38 is the most popular standard for industrial neodymium magnets, offering an optimal price-to-power ratio and high resistance to demagnetization. If you need even stronger magnets in the same volume (Ø45x15), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.
The presented product is a neodymium magnet with precisely defined parameters: diameter 45 mm and height 15 mm. The key parameter here is the lifting capacity amounting to approximately 48.55 kg (force ~476.32 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 oxidation, giving it an aesthetic, silvery shine.
This rod magnet is magnetized axially (along the height of 15 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.

Strengths as well as weaknesses of rare earth magnets.

Pros

Besides their magnetic performance, neodymium magnets are valued for these benefits:
  • They do not lose power, even after around ten years – the reduction in lifting capacity is only ~1% (according to tests),
  • They retain their magnetic properties even under strong external field,
  • In other words, due to the metallic surface of nickel, the element becomes visually attractive,
  • The surface of neodymium magnets generates a strong magnetic field – this is a key feature,
  • Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
  • Possibility of accurate modeling as well as modifying to complex conditions,
  • Wide application in modern technologies – they are commonly used in computer drives, motor assemblies, medical devices, also modern systems.
  • Compactness – despite small sizes they generate large force, making them ideal for precision applications

Cons

Drawbacks and weaknesses of neodymium magnets: weaknesses and usage proposals
  • They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
  • When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
  • When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
  • Limited ability of producing threads in the magnet and complicated shapes - recommended is a housing - magnet mounting.
  • Health risk related to microscopic parts of magnets pose a threat, if swallowed, which becomes key in the context of child health protection. Additionally, tiny parts of these devices are able to be problematic in diagnostics medical when they are in the body.
  • High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

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

Breakaway force is the result of a measurement for ideal contact conditions, including:
  • with the use of a yoke made of low-carbon steel, ensuring maximum field concentration
  • possessing a thickness of at least 10 mm to avoid saturation
  • with a surface perfectly flat
  • without any air gap between the magnet and steel
  • for force applied at a right angle (in the magnet axis)
  • at temperature room level

Determinants of practical lifting force of a magnet

Effective lifting capacity is affected by working environment parameters, including (from priority):
  • Gap (between the magnet and the metal), as even a microscopic distance (e.g. 0.5 mm) results in a drastic drop in force by up to 50% (this also applies to paint, corrosion or debris).
  • Force direction – remember that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
  • Plate thickness – too thin steel causes magnetic saturation, causing part of the power to be escaped into the air.
  • Material composition – not every steel attracts identically. High carbon content worsen the interaction with the magnet.
  • Surface finish – ideal contact is obtained only on polished steel. Rough texture create air cushions, reducing force.
  • Operating temperature – NdFeB sinters have a sensitivity to temperature. At higher temperatures they are weaker, and at low temperatures gain strength (up to a certain limit).

Lifting capacity was assessed using a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, in contrast under parallel forces the load capacity is reduced by as much as fivefold. Additionally, even a small distance between the magnet and the plate lowers the lifting capacity.

Warnings
Fragile material

Despite the nickel coating, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may crumble into hazardous fragments.

Magnetic interference

A powerful magnetic field negatively affects the functioning of magnetometers in smartphones and navigation systems. Keep magnets close to a device to avoid breaking the sensors.

Demagnetization risk

Do not overheat. NdFeB magnets are sensitive to temperature. If you need resistance above 80°C, ask us about HT versions (H, SH, UH).

Do not underestimate power

Handle magnets consciously. Their powerful strength can surprise even professionals. Plan your moves and do not underestimate their power.

Pinching danger

Big blocks can smash fingers in a fraction of a second. Under no circumstances put your hand between two strong magnets.

Keep away from computers

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

Medical implants

For implant holders: Powerful magnets disrupt electronics. Maintain at least 30 cm distance or request help to work with the magnets.

Keep away from children

Strictly keep magnets out of reach of children. Choking hazard is high, and the effects of magnets clamping inside the body are life-threatening.

Dust explosion hazard

Fire hazard: Rare earth powder is highly flammable. Do not process magnets in home conditions as this risks ignition.

Sensitization to coating

Allergy Notice: The Ni-Cu-Ni coating contains nickel. If an allergic reaction happens, immediately stop handling magnets and use protective gear.
