Magnetic force drops sharply with every subsequent millimeter of spacing. Note that even the smallest gap (e.g., dirt, paint, veneer) significantly diminishes the holding power. Neodymiums work optimally in perfect adhesion; air break weakens the force. Analyze how flashily the load capacity drop, when the magnet does not adhere flatly to the steel surface. When designing the arrangement, avoid redundant distances.

This section indicates the theoretical holding capacity required to cause the downward movement of the magnet vertically along a upright steel wall (considering standard friction coefficient). The holding force is relative to the air gap between the magnet and the metal.

When hanging a magnet on a upright plane (e.g., a board), it you can count on just about 20%-30% of its nominal power. Gravity and a weak degree of grip mean that products slide down faster than they detach. Planning a hanger? Remember that the sliding force is much weaker than the perpendicular breakaway force. On a painted metal, the holder will slide down under a noticeably lighter weight. Using a rubber pad can effectively improve the result.

A thin metal plate is unable to absorb the entire magnetic field, which wastes potential of the holder. Should you mount a strong magnet to a thin surface, the flux will pass right through and the pull force will drop sharply. To utilize the maximum of this neodymium's potential, you require a sufficiently solid backing of steel. The saturation effect means that on sheet metal structures (e.g., thin profiles), the product shows lower pull force. We recommend selecting the steel dimension according to the table below.

Ordinary NdFeB products irreversibly lose power above the temperature limit. Watch out for overheating – heat can permanently demagnetize this magnet. As the temperature rises, the neodymium's capacity momentarily drops. Avoid using this magnet close to ovens higher than its working range. Too high temperature will lead to destruction of magnetic properties.

*Important note: Heat tolerance depends not only on the material grade, but also on the magnet's shape. Thin magnets (low Pc) are more susceptible to demagnetization under lower heat stress than long magnets. Warning indicator in the table points to a risk of irreversible loss for this particular item.

Two strong neodymiums interact from a wider radius than a magnet and sheet combination. The setup of two magnets produces a massive flux and a larger range of performance. Want to build a powerful holder? Use a pair of magnets instead of a neodymium and a striker plate. Be careful that when connecting a pair of magnets, the pinch force is huge. The repulsion force is a bit weaker than the connection force, but still impressive.
*The magnetic induction in repulsion mode is approximately ~0 Gs at the geometric center between the magnets (caused by magnetic field nullification).
* Estimates refer to friction force of two matching magnets (friction ~0.15 for Ni-Ni plating).

Powerful magnet radiation is a serious hazard to electronics and pacemakers. These neodymiums produce a flux that destroys function of digital equipment. Be aware: the unseen radiation acts through matter and plastic. Exceptional care must be taken by people with hearing aids and insulin pumps. Also at risk are: automatic timepieces, remotes, membranes, and screens. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

Magnetic elements are very brittle – a collision with steel can result in shattering. Watch the impact speed – a neodymium left loose becomes dangerous. Striking energy can trigger coating fragments or injury to skin. Hold the magnet firmly during installation so it doesn't slam with momentum against the metal. A collision at high speed almost guarantees destruction of the magnet. Wear safety glasses when working with large magnets.

Corrosion warning: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

The magnetic field penetrates through water without any losses. 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 surface, the magnet holds merely a fraction of its nominal pull.

2. Efficiency vs thickness

*Thin steel (e.g. computer case) drastically 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) = 0.53

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 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.

MW 38x3.5 / N38 - cylindrical magnet

15.83 ZŁ brutto / pcs

This product is an exceptionally strong cylindrical magnet, produced from advanced NdFeB material, which, with dimensions of Ø70x30 mm, guarantees the highest energy density. The MW 70x30 / N38 component features an accuracy of ±0.1mm and industrial build quality, making it an excellent solution for the most demanding engineers and designers. As a cylindrical magnet with significant force (approx. 144.18 kg), this product is in stock from our warehouse in Poland, ensuring quick order fulfillment. Moreover, its Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

It successfully proves itself in modeling, advanced automation, and broadly understood industry, serving as a fastening or actuating element. Thanks to the pull force of 1414.37 N with a weight of only 865.9 g, this cylindrical magnet 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., 70.1 mm) using epoxy glues. To ensure long-term durability in industry, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.

Magnets NdFeB grade N38 are suitable for the majority of applications in automation and machine building, where excessive miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø70x30), 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 70 mm and height 30 mm. The key parameter here is the holding force amounting to approximately 144.18 kg (force ~1414.37 N), which, with such compact dimensions, proves the high grade 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 30 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 diametrically if your project requires it.

Pros and cons of neodymium magnets.

Pros

In addition to their long-term stability, neodymium magnets provide the following advantages:

They do not lose strength, even over approximately 10 years – the decrease in lifting capacity is only ~1% (theoretically),
They have excellent resistance to magnetic field loss due to opposing magnetic fields,
Thanks to the elegant finish, the layer of nickel, gold, or silver-plated gives an aesthetic appearance,
Magnetic induction on the working part of the magnet remains maximum,
Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
Possibility of accurate forming and adjusting to precise requirements,
Wide application in modern industrial fields – they are commonly used in data components, electromotive mechanisms, medical devices, and technologically advanced constructions.
Thanks to their power density, small magnets offer high operating force, in miniature format,

Weaknesses

Disadvantages of neodymium magnets:

They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only protects 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 drop of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
Limited possibility of producing nuts in the magnet and complex forms - recommended is a housing - mounting mechanism.
Health risk related to microscopic parts of magnets pose a threat, if swallowed, which gains importance in the context of child safety. Furthermore, tiny parts of these magnets can complicate diagnosis medical when they are in the body.
With large orders the cost of neodymium magnets can be a barrier,

Holding force characteristics

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

The force parameter is a result of laboratory testing conducted under standard conditions:

using a base made of mild steel, functioning as a magnetic yoke
possessing a thickness of min. 10 mm to ensure full flux closure
characterized by smoothness
under conditions of ideal adhesion (surface-to-surface)
during pulling in a direction perpendicular to the plane
in stable room temperature

Impact of factors on magnetic holding capacity in practice

It is worth knowing that the working load may be lower depending on elements below, in order of importance:

Space between surfaces – every millimeter of distance (caused e.g. by varnish or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
Angle of force application – maximum parameter is reached only during perpendicular pulling. The resistance to sliding of the magnet along the surface is typically many times smaller (approx. 1/5 of the lifting capacity).
Steel thickness – too thin plate does not close the flux, causing part of the flux to be wasted to the other side.
Material composition – not every steel attracts identically. High carbon content weaken the interaction with the magnet.
Surface condition – ground elements guarantee perfect abutment, which improves force. Uneven metal weaken the grip.
Thermal factor – high temperature reduces magnetic field. Too high temperature can permanently demagnetize the magnet.

Lifting capacity was assessed using a polished steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, however under attempts to slide the magnet the load capacity is reduced by as much as 75%. Moreover, even a small distance between the magnet and the plate lowers the load capacity.

Precautions when working with NdFeB magnets

Electronic hazard

Powerful magnetic fields can erase data on credit cards, HDDs, and other magnetic media. Stay away of at least 10 cm.

Eye protection

NdFeB magnets are sintered ceramics, which means they are very brittle. Impact of two magnets will cause them cracking into small pieces.

Demagnetization risk

Watch the temperature. Heating the magnet to high heat will permanently weaken its properties and strength.

Danger to pacemakers

Patients with a pacemaker must maintain an absolute distance from magnets. The magnetism can stop the operation of the implant.

Do not drill into magnets

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

Finger safety

Big blocks can break fingers instantly. Do not put your hand between two attracting surfaces.

Skin irritation risks

Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If skin irritation occurs, cease working with magnets and wear gloves.

Caution required

Be careful. Neodymium magnets attract from a distance and snap with massive power, often faster than you can react.

Phone sensors

An intense magnetic field interferes with the operation of magnetometers in smartphones and GPS navigation. Maintain magnets close to a device to avoid damaging the sensors.

Choking Hazard

Always keep magnets away from children. Choking hazard is high, and the consequences of magnets clamping inside the body are fatal.
