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.

Grip strength decreases drastically with every mm of gap. Keep in mind that every additional insulation layer (e.g., dirt, varnish, rust) noticeably weakens the grip. Magnetic products hold optimally in perfect adhesion; distance weakens the force. See how rapidly the load capacity drop, when the product does not adhere tightly to the metal substrate. When calculating the arrangement, eliminate redundant distances.

The table below defines the estimated shear load necessary to initiate the sliding of the magnet down along a upright steel plate (assuming standard friction). This parameter varies with the distance between the magnet and the metal.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
MW 15x10 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	2.31 kg / 5.09 LBS 2310.0 g / 22.7 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.54 kg / 3.40 LBS 1540.0 g / 15.1 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.77 kg / 1.70 LBS 770.0 g / 7.6 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	3.85 kg / 8.49 LBS 3850.0 g / 37.8 N

When mounting a element on a upright surface (e.g., a car body), it will maintain barely approx. 1/5 of its maximum pull force. Gravitational force and a weak degree of grip mean that magnets move down easier than they pull off. Want to create a wall mount? Note that the sliding force is much weaker than the maximum static pull force. On a painted metal, the magnet will slip down under a much lighter load. Utilizing a rubberized coating can significantly increase the grip.

A thin sheet is unable to conduct the full magnetic flux, which squanders power of the holder. Should you attach a powerful product to a weak sheet, the flux will pass right through and the pull force will drop sharply. To squeeze the maximum of this magnet's power, you need a suitably thick backing of metal. The saturation phenomenon means that on sheet metal structures (e.g., car bodies), the holder shows lower pull force. We recommend selecting the steel thickness according to the table below.

Standard neodymium magnets lose strength after exceeding the maximum temperature. Watch out for overheating – excessive heat can permanently damage this product. As the temperature rises, the neodymium's power momentarily drops. Refrain from using this product close to heaters higher than its operating temperature limit. Too high temperature will result in destruction of magnetism.

*Important note: Temperature resistance is determined by both grade, and the Permeance Coefficient Pc. Low-profile magnets (low Pc) risk losing magnetic properties sooner compared to rod magnets. Warning indicator in the table indicates a risk of irreversible loss for this specific geometry.

Two magnets interact from a wider radius than a neodymium and metal combination. The connection of magnet-to-magnet produces a massive flux and a further horizon of operation. Designing a solid fastener? Apply two magnets instead of one magnet and a steel. Remember that when bringing together two magnets, the collision energy is extreme. The repulsion force is a bit weaker than the connection force, but still impressive.
*The magnetic induction between like poles drops to ~0 Gs at the midpoint of the gap (due to field cancellation).
Attention: Estimates apply to sliding force of two matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni coating).

Neodymium magnets are delicate – a collision with steel can result in shattering. Control the attraction moment – a neodymium left loose speeds with massive force. Impact energy can cause material chips or dangerous crushing to skin. Be sure to control the product during mounting so it doesn't hit with great force against the metal. A collision at high speed means shattering of the magnet. Wear safety glasses when working with powerful specimens.

Corrosion warning: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.

Water displaces steel, making heavy objects slightly lighter. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Vertical hold

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

2. Efficiency vs thickness

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

3. Temperature resistance

*For standard magnets, the max working temp is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.71

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 P_c (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 P_c 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 rod magnet, composed of durable NdFeB material, which, at dimensions of Ø15x10 mm, guarantees maximum efficiency. The MW 15x10 / N38 component is characterized by a tolerance of ±0.1mm and professional build quality, making it an excellent solution for professional engineers and designers. As a magnetic rod with significant force (approx. 7.70 kg), this product is in stock from our European logistics center, ensuring quick order fulfillment. Additionally, its triple-layer Ni-Cu-Ni coating effectively protects it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

It finds application in DIY projects, advanced robotics, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 75.51 N with a weight of only 13.25 g, this cylindrical magnet is indispensable in electronics 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 precision component. To ensure long-term durability in automation, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.

Grade N38 is the most popular standard for professional neodymium magnets, offering a great economic balance and operational stability. If you need even stronger magnets in the same volume (Ø15x10), 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 Ø15x10 mm, which, at a weight of 13.25 g, makes it an element with impressive magnetic energy density. The value of 75.51 N means that the magnet is capable of holding a weight many times exceeding its own mass of 13.25 g. The product has a [NiCuNi] coating, which protects the surface against oxidation, giving it an aesthetic, silvery shine.

This cylinder is magnetized axially (along the height of 10 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 through the diameter if your project requires it.

Strengths and weaknesses of Nd₂Fe₁₄B magnets.

Benefits

Besides their durability, neodymium magnets are valued for these benefits:

They retain magnetic properties for around ten years – the loss is just ~1% (according to analyses),
They are extremely resistant to demagnetization induced by external disturbances,
A magnet with a metallic silver surface has better aesthetics,
Magnetic induction on the top side of the magnet turns out to be very high,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
Possibility of custom machining as well as adapting to defined applications,
Wide application in future technologies – they serve a role in mass storage devices, drive modules, precision medical tools, and technologically advanced constructions.
Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,

Weaknesses

Drawbacks and weaknesses of neodymium magnets and ways of using them

To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and 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 usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
Limited possibility of producing nuts in the magnet and complex forms - preferred is cover - magnetic holder.
Health risk resulting from small fragments of magnets pose a threat, in case of ingestion, which gains importance in the context of child health protection. Furthermore, tiny parts of these devices are able to complicate diagnosis medical in case of swallowing.
With mass production the cost of neodymium magnets is economically unviable,

Pull force analysis

Best holding force of the magnet in ideal parameters – what affects it?

The force parameter is a result of laboratory testing executed under specific, ideal conditions:

on a plate made of mild steel, optimally conducting the magnetic field
possessing a thickness of min. 10 mm to ensure full flux closure
characterized by lack of roughness
without any clearance between the magnet and steel
for force applied at a right angle (pull-off, not shear)
at ambient temperature room level

What influences lifting capacity in practice

In practice, the actual lifting capacity depends on many variables, ranked from the most important:

Clearance – existence of any layer (rust, tape, gap) interrupts the magnetic circuit, which lowers power rapidly (even by 50% at 0.5 mm).
Direction of force – highest force is obtained only during perpendicular pulling. The shear force of the magnet along the surface is usually many times lower (approx. 1/5 of the lifting capacity).
Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
Steel grade – the best choice is pure iron steel. Hardened steels may generate lower lifting capacity.
Surface finish – ideal contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
Thermal factor – high temperature reduces pulling force. Too high temperature can permanently demagnetize the magnet.

Lifting capacity was assessed with the use of a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, in contrast under parallel forces the load capacity is reduced by as much as 75%. Moreover, even a slight gap between the magnet’s surface and the plate decreases the load capacity.

H&S for magnets

Data carriers

Data protection: Strong magnets can ruin data carriers and delicate electronics (pacemakers, medical aids, mechanical watches).

Pacemakers

Life threat: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have electronic implants.

Compass and GPS

An intense magnetic field interferes with the operation of magnetometers in smartphones and GPS navigation. Maintain magnets near a device to prevent breaking the sensors.

Mechanical processing

Dust generated during machining of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.

Choking Hazard

Neodymium magnets are not suitable for play. Accidental ingestion of multiple magnets may result in them attracting across intestines, which poses a severe health hazard and necessitates immediate surgery.

Do not overheat magnets

Regular neodymium magnets (grade N) lose power when the temperature goes above 80°C. This process is irreversible.

Material brittleness

NdFeB magnets are ceramic materials, which means they are fragile like glass. Impact of two magnets will cause them shattering into shards.

Conscious usage

Be careful. Rare earth magnets act from a distance and connect with huge force, often faster than you can move away.

Allergic reactions

Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If skin irritation appears, cease handling magnets and use protective gear.

Hand protection

Watch your fingers. Two powerful magnets will snap together instantly with a force of massive weight, destroying everything in their path. Exercise extreme caution!
