Grip strength weakens significantly with every subsequent millimeter of spacing. Keep in mind that even the smallest gap (e.g., dirt, varnish, dust) noticeably reduces the pull force. Magnets work most effectively during direct contact; gap drastically cuts the power. Notice how flashily the parameters fall, when the magnet does not adhere tightly to the metal substrate. When calculating the arrangement, eliminate additional spacers.

This section presents the theoretical holding capacity required to start the downward movement of the magnet down along a upright metal surface (assuming standard friction). The holding force depends on the distance between the magnet and the surface.

When mounting a holder on a upright wall (e.g., a board), it will maintain just approx. 20%-30% of its nominal power. Gravitational force as well as a weak degree of grip influence the fact that holders slide down easier than they detach. Want to create a hanger? Remember that the shear force is significantly lower than the perpendicular breakaway force. On a slippery surface, the element will give way down under a significantly smaller weight. Utilizing a rubberized layer can drastically improve the result.

A thin metal plate is unable to absorb the entire magnetic field, which weakens actual performance of the holder. Should you attach a powerful product to a thin surface, the magnetism will pass right through and the holding will be smaller. To utilize full efficiency of this magnet's power, you need a suitably thick element of steel. The saturation phenomenon means that on delicate walls (e.g., car bodies), the product works worse. We recommend selecting the steel dimension based on the following data.

Ordinary NdFeB products change their properties strength after exceeding the maximum temperature. Watch out for overheating – high temperature can permanently destroy this product. As the temperature rises, the neodymium's capacity momentarily decreases. Do not use this magnet close to heaters higher than its safe range. Too high temperature will result in destruction of magnetism.

*Engineering note: Heat tolerance is determined by both grade, but also on the magnet's shape. Low-profile magnets (pancake types) are more susceptible to demagnetization under lower heat stress than taller cylinders. Warning indicator in the table signals permanent field degradation for this particular item.

Two magnetic products attract each other from a much further distance than a magnet and steel combination. The setup of magnet-to-magnet creates a more powerful interaction and a wider radius of operation. Planning to create a solid fastener? Utilize two neodymiums instead of a neodymium and a striker plate. Be careful that when connecting a pair of magnets, the collision energy is extreme. The levitation is marginally weaker than the attraction, but still impressive.
*The magnetic induction in repulsion mode drops to ~0 Gs at the midpoint of the gap (due to field cancellation).
Attention: Calculations refer to sliding force of a pair of identical magnets (friction coefficient ~0.15 for Ni-Ni plating).

A strong magnetic field poses a real danger to electronics and medical implants. These neodymiums generate a flux that disrupts operation of sensitive medical devices. Be aware: the unseen radiation acts through matter and housings. Special caution must be exercised by people with cochlear implants and drug dispensers. Influence will be felt by: automatic timepieces, car keys, membranes, and screens. Do not bring the product near payment cards, HDD media, or sensitive navigation tools.

Magnetic elements are prone to chipping – a strong collision with metal causes immediate chipping. Control the attraction moment – a magnet released freely speeds with massive force. Impact energy can trigger coating fragments or injury to skin. Always hold the magnet during installation so it doesn't slam with momentum against the metal. A collision at high speed means shattering of the neodymium. Wear safety glasses when handling with powerful specimens.

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

1. Wall mount (shear)

*Note: On a vertical wall, the magnet retains only approx. 20-30% of its perpendicular strength.

2. Plate thickness effect

*Thin steel (e.g. computer case) drastically limits the holding force.

3. Thermal stability

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.61

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 presented product is a very strong cylindrical magnet, made from durable NdFeB material, which, with dimensions of Ø15x8 mm, guarantees optimal power. The MW 15x8 / N38 component features high dimensional repeatability and professional build quality, making it a perfect solution for the most demanding engineers and designers. As a magnetic rod with impressive force (approx. 7.37 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring lightning-fast order fulfillment. Furthermore, its Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is created for building electric motors, advanced sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the pull force of 72.28 N with a weight of only 10.6 g, this rod is indispensable in electronics and wherever every gram matters.

Since our magnets have a tolerance of ±0.1mm, the best method is to glue them into holes with a slightly larger diameter (e.g., 15.1 mm) using epoxy glues. To ensure stability 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 modeling and machine building, where excessive miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø15x8), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.

This model is characterized by dimensions Ø15x8 mm, which, at a weight of 10.6 g, makes it an element with high magnetic energy density. The key parameter here is the lifting capacity amounting to approximately 7.37 kg (force ~72.28 N), which, with such defined dimensions, proves the high grade of the NdFeB material. The product has a [NiCuNi] coating, which protects the surface against external factors, 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 15 mm. 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.

Advantages as well as disadvantages of neodymium magnets.

Pros

Apart from their strong holding force, neodymium magnets have these key benefits:

Their power is maintained, and after around 10 years it drops only by ~1% (according to research),
Neodymium magnets remain exceptionally resistant to loss of magnetic properties caused by magnetic disturbances,
By using a smooth layer of gold, the element has an proper look,
Magnets are distinguished by very high magnetic induction on the active area,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
Considering the option of precise shaping and customization to unique solutions, NdFeB magnets can be manufactured in a variety of shapes and sizes, which makes them more universal,
Universal use in modern industrial fields – they are commonly used in mass storage devices, electric motors, precision medical tools, as well as other advanced devices.
Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,

Limitations

Drawbacks and weaknesses of neodymium magnets and ways of using them

At very strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop 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
When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
Limited ability of making threads in the magnet and complex shapes - recommended is casing - magnet mounting.
Possible danger resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Additionally, small elements of these magnets are able to disrupt the diagnostic process medical when they are in the body.
With mass production the cost of neodymium magnets is a challenge,

Pull force analysis

Breakaway strength of the magnet in ideal conditions – what contributes to it?

Information about lifting capacity is the result of a measurement for optimal configuration, including:

on a plate made of mild steel, effectively closing the magnetic field
possessing a thickness of at least 10 mm to avoid saturation
with an ground touching surface
under conditions of no distance (surface-to-surface)
during pulling in a direction perpendicular to the mounting surface
at temperature room level

Magnet lifting force in use – key factors

During everyday use, the actual lifting capacity depends on many variables, ranked from crucial:

Gap between surfaces – every millimeter of separation (caused e.g. by varnish or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the maximum value.
Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
Plate material – mild steel gives the best results. Alloy admixtures lower magnetic permeability and holding force.
Surface quality – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Unevenness creates an air distance.
Thermal factor – hot environment weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.

Lifting capacity was assessed with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under vertically applied force, in contrast under shearing force the load capacity is reduced by as much as 5 times. In addition, even a minimal clearance between the magnet’s surface and the plate reduces the holding force.

Precautions when working with NdFeB magnets

Bodily injuries

Watch your fingers. Two powerful magnets will join instantly with a force of several hundred kilograms, crushing anything in their path. Be careful!

Impact on smartphones

A strong magnetic field disrupts the functioning of magnetometers in smartphones and GPS navigation. Maintain magnets close to a smartphone to prevent breaking the sensors.

Electronic devices

Data protection: Neodymium magnets can ruin data carriers and delicate electronics (heart implants, hearing aids, mechanical watches).

Skin irritation risks

Medical facts indicate that nickel (standard magnet coating) is a potent allergen. If your skin reacts to metals, refrain from touching magnets with bare hands and opt for encased magnets.

Handling rules

Before use, read the rules. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.

Flammability

Machining of NdFeB material carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.

Maximum temperature

Control the heat. Exposing the magnet to high heat will destroy its magnetic structure and strength.

Product not for children

Adult use only. Tiny parts pose a choking risk, causing intestinal necrosis. Store out of reach of kids and pets.

Life threat

Patients with a pacemaker have to keep an safe separation from magnets. The magnetic field can interfere with the functioning of the implant.

Eye protection

Despite the nickel coating, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.
