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 decreases sharply per each millimeter of distance. Remember that every additional insulation layer (e.g., contamination, paint, veneer) strongly reduces the pull force. Magnetic products work optimally at the point of direct contact; air break drastically cuts the power. Observe how rapidly the load capacity fall, when the magnet does not touch flatly to the metal substrate. When designing the mounting, discard additional spacers.

When placing a magnet on a upright surface (e.g., a board), it you can count on just about 1/5 of nominal attraction strength. Gravity as well as a weak degree of grip mean that holders slide down faster than they pull off. Designing a hanger? Consider that the sliding force is significantly lower than the maximum static pull force. On a slippery surface, the element will slip down under a much lighter weight. Using a rubber coating can effectively improve the result.

A too thin steel is not enough to focus the full magnetic flux, which squanders power of the holder. If you mount a strong magnet to a thin surface, the flux will penetrate right through and the attraction force will be weaker. To achieve full efficiency of this magnet's potential, you require a sufficiently solid backing of steel. The saturation effect means that on thin elements (e.g., appliance housings), the holder works worse. We suggest choosing the steel thickness from these parameters.

Classic neodymiums irreversibly lose parameters after exceeding the maximum temperature. Avoid high temperatures – heat can permanently damage this magnet. With increasing heat, the neodymium's force briefly drops. Refrain from using this magnet close to ovens exceeding its safe range. Ignoring the limit will result in irreversible degradation of magnetism.
*Important note: Thermal stability is determined by both grade, and the Permeance Coefficient Pc. Low-profile magnets (low permeance coefficient) may lose charge permanently under lower heat stress than taller cylinders. The danger warning in the table points to a risk of irreversible loss for this particular item.

Two strong neodymiums interact from a significantly greater distance than a magnet and steel setup. The setup of magnet-to-magnet generates a stronger field and a further horizon of action. Planning to create a powerful holder? Use a pair of magnets instead of a neodymium and a steel. Exercise caution that when bringing together two magnets, the impact force is massive. The levitation is a bit weaker than the connection force, but still large.
*The magnetic induction in repulsion mode reaches ~0 Gs at the geometric center of the gap (resulting from vector opposition).
Important: Calculations show shear force of dual identical magnets (friction ~0.15 for Ni-Ni plating).

A strong magnetic field poses a serious hazard to electronic devices as well as medical implants. These neodymiums produce a field that destroys function of digital equipment. Be aware: the invisible magnetic field penetrates the body and glass. Exceptional care must be taken by people with hearing aids and insulin pumps. Influence will be felt by: automatic timepieces, remotes, membranes, and displays. Do not place the magnet near cards, hard drives, or precise measuring instruments.

Neodymium magnets are very brittle – a strong collision with metal risks their cracking. Pay attention to connection velocity – a magnet released freely becomes dangerous. Impact energy can cause material chips or painful pinches to fingers. Always hold the magnet during installation so it doesn't hit with great force against the metal. A collision at high speed ends with a crack of the neodymium. Wear eye protection when handling with powerful specimens.

Contrary to myths, water does not block the magnetic field. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Shear force

*Warning: On a vertical wall, the magnet holds only approx. 20-30% of its max power.

2. Steel thickness impact

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

3. Temperature resistance

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

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.22

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.

This product is an exceptionally strong cylindrical magnet, manufactured from durable NdFeB material, which, with dimensions of Ø35x5 mm, guarantees maximum efficiency. This specific item 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 impressive force (approx. 9.25 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring quick order fulfillment. Furthermore, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.
This model is ideal for building generators, advanced Hall effect sensors, and efficient filters, where field concentration on a small surface counts. Thanks to the pull force of 90.73 N with a weight of only 36.08 g, this rod is indispensable in miniature devices and wherever low weight is crucial.
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., 35.1 mm) using epoxy glues. To ensure stability in automation, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.
Grade N38 is the most frequently chosen standard for industrial neodymium magnets, offering an optimal price-to-power ratio and high resistance to demagnetization. If you need the strongest magnets in the same volume (Ø35x5), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.
The presented product is a neodymium magnet with precisely defined parameters: diameter 35 mm and height 5 mm. The value of 90.73 N means that the magnet is capable of holding a weight many times exceeding its own mass of 36.08 g. The product has a [NiCuNi] coating, which protects the surface against oxidation, giving it an aesthetic, silvery shine.
Standardly, the magnetic axis runs through the center of the cylinder, causing the greatest attraction force to occur on the bases with a diameter of 35 mm. 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 as well as weaknesses of neodymium magnets.

Pros

Apart from their strong magnetic energy, neodymium magnets have these key benefits:
  • They retain full power for around 10 years – the drop is just ~1% (according to analyses),
  • Magnets effectively protect themselves against loss of magnetization caused by ambient magnetic noise,
  • A magnet with a shiny gold surface looks better,
  • Magnetic induction on the top side of the magnet is maximum,
  • Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
  • Thanks to versatility in shaping and the ability to modify to individual projects,
  • Key role in modern industrial fields – they are utilized in HDD drives, drive modules, diagnostic systems, also other advanced devices.
  • Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Disadvantages

Cons of neodymium magnets and ways of using them
  • They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only shields the magnet but also increases its resistance to damage
  • Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
  • They rust in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
  • We suggest cover - magnetic mount, due to difficulties in realizing nuts inside the magnet and complicated forms.
  • Potential hazard related to microscopic parts of magnets are risky, if swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that tiny parts of these products can complicate diagnosis medical when they are in the body.
  • High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Pull force analysis

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

Information about lifting capacity was determined for the most favorable conditions, taking into account:
  • on a base made of structural steel, perfectly concentrating the magnetic field
  • possessing a thickness of minimum 10 mm to avoid saturation
  • characterized by lack of roughness
  • without the slightest air gap between the magnet and steel
  • for force acting at a right angle (in the magnet axis)
  • at room temperature

Impact of factors on magnetic holding capacity in practice

Please note that the working load will differ influenced by elements below, in order of importance:
  • Clearance – the presence of foreign body (rust, dirt, air) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
  • Force direction – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
  • Base massiveness – insufficiently thick sheet causes magnetic saturation, causing part of the power to be lost into the air.
  • Metal type – different alloys attracts identically. Alloy additives weaken the attraction effect.
  • Surface quality – the more even the surface, the larger the contact zone and higher the lifting capacity. Roughness acts like micro-gaps.
  • Temperature – temperature increase causes a temporary drop of induction. Check the thermal limit for a given model.

Lifting capacity was assessed by applying a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular pulling force, however under parallel forces the holding force is lower. In addition, even a slight gap between the magnet’s surface and the plate reduces the load capacity.

Safe handling of neodymium magnets
Fragile material

Watch out for shards. Magnets can explode upon violent connection, ejecting sharp fragments into the air. We recommend safety glasses.

Conscious usage

Handle with care. Neodymium magnets act from a distance and snap with massive power, often faster than you can react.

No play value

These products are not suitable for play. Accidental ingestion of several magnets may result in them connecting inside the digestive tract, which poses a direct threat to life and necessitates urgent medical intervention.

Skin irritation risks

Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction happens, cease working with magnets and use protective gear.

Health Danger

Patients with a pacemaker must keep an safe separation from magnets. The magnetic field can interfere with the operation of the implant.

Data carriers

Powerful magnetic fields can corrupt files on credit cards, hard drives, and storage devices. Keep a distance of at least 10 cm.

Fire risk

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

Heat warning

Avoid heat. Neodymium magnets are susceptible to heat. If you need operation above 80°C, look for special high-temperature series (H, SH, UH).

GPS Danger

Note: rare earth magnets produce a field that confuses sensitive sensors. Maintain a separation from your phone, tablet, and navigation systems.

Physical harm

Large magnets can smash fingers in a fraction of a second. Do not place your hand betwixt two attracting surfaces.
