Grip strength decreases sharply with every subsequent millimeter of spacing. Remember that every additional insulation layer (e.g., contamination, varnish, rust) noticeably weakens the grip. Magnets work optimally at the point of direct contact; distance kills the force. Observe how flashily the pull force plummet, when the magnet does not adhere directly to the metal substrate. When designing the arrangement, eliminate additional spacers.

This section defines the estimated shear load required to initiate the downward movement of the magnet down along a upright metal surface (assuming typical friction). This parameter is relative to the separation distance between the magnet and the metal.

Table 3: Wall mounting (shearing) - vertical pull
MW 18x1.5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.29 kg / 0.63 pounds 285.0 g / 2.8 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.19 kg / 0.42 pounds 190.0 g / 1.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.10 kg / 0.21 pounds 95.0 g / 0.9 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.48 kg / 1.05 pounds 475.0 g / 4.7 N

When mounting a magnet on a vertical plane (e.g., a fridge), it will only hold barely about 1/5 of its nominal power. Gravitational force as well as a weak degree of grip mean that products slip easier than they pop off the substrate. Want to create a wall mount? Remember that the sliding force is significantly lower than the perpendicular breakaway force. On a smooth steel, the element will slide down under a much lighter load. Using a rubber pad can drastically improve the result.

12 mm	100%	0.95 kg / 2.09 pounds 950.0 g / 9.3 N

A too thin steel is incapable of focus the full magnetic flux, which weakens actual performance of the magnet. If you attach a powerful product to a thin surface, the field will pass right through and the attraction force will be weaker. To squeeze full efficiency of this magnet's potential, you need a suitably thick backing of steel. The saturation phenomenon causes that on delicate walls (e.g., thin profiles), the holder shows lower pull force. We advise picking the steel thickness from these parameters.

Classic neodymiums change their properties strength past the thermal threshold. Avoid high temperatures – heat can permanently demagnetize this product. As the temperature rises, the magnet's power temporarily lowers. Do not use this magnet near heat sources exceeding its working range. Ignoring the limit will lead to destruction of magnetic properties.

*Engineering note: Thermal stability depends not only on the material grade, as well as the dimension ratios. Low-profile magnets (pancake types) are more susceptible to demagnetization under lower heat stress compared to rod magnets. Red status in the table signals a risk of irreversible loss for this particular item.

Two magnetic products attract each other from a much further distance than a neodymium and metal setup. The setup of magnet-to-magnet generates a stronger field and a larger range of operation. Designing a strong closure? Apply two magnets instead of one magnet and a striker plate. Be careful that when connecting a pair of magnets, the pinch force is extreme. The repulsion force is slightly lower than the connection force, but still large.
*The magnetic induction in repulsion mode reaches ~0 Gs at the midpoint between the magnets (resulting from vector opposition).
Note: Estimates demonstrate sliding force of two matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni coating).

A strong magnetic field poses a serious hazard to electronics and pacemakers. These magnets produce a flux that disrupts operation of digital equipment. Notice: the unseen radiation penetrates the body and glass. Increased vigilance must be exercised by people with cochlear implants and insulin pumps. The risk also applies to: mechanical watches, remotes, membranes, and displays. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Table 8: Dynamics (kinetic energy) - collision effects
MW 18x1.5 / N38

Start from (mm)	Speed (km/h)	Energy (J)

100 mm	58.12 km/h (16.15 m/s)	0.37 J

Neodymium magnets are delicate – a collision with steel risks their cracking. Pay attention to connection velocity – a neodymium left loose turns into a projectile. Striking energy can cause material chips or dangerous crushing to fingers. Be sure to control the product during mounting so it doesn't hit violently against the steel surface. A contact at a velocity of dozens of km/h means shattering of the neodymium. Wear safety glasses when working with large magnets.

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

In water, the magnet feels stronger thanks to Archimedes' principle. However, remember the water resistance when pulling the rope quickly.

1. Sliding resistance

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

2. Steel thickness impact

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

3. Power loss vs temp

*For N38 material, 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) = 0.13

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 cylindrical magnet, produced from modern NdFeB material, which, with dimensions of Ø18x1.5 mm, guarantees maximum efficiency. This specific item features high dimensional repeatability and industrial build quality, making it an ideal solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 0.95 kg), this product is in stock from our European logistics center, ensuring quick order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

It successfully proves itself in DIY projects, advanced automation, and broadly understood industry, serving as a positioning or actuating element. Thanks to the pull force of 9.34 N with a weight of only 2.86 g, this cylindrical magnet is indispensable in miniature devices and wherever every gram matters.

Due to the brittleness of the NdFeB material, we absolutely advise against force-fitting (so-called press-fit), as this risks chipping the coating of this professional component. To ensure long-term durability in automation, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.

Magnets NdFeB grade N38 are strong enough for the majority of applications in modeling and machine building, where extreme miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø18x1.5), 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 Ø18x1.5 mm, which, at a weight of 2.86 g, makes it an element with impressive magnetic energy density. The key parameter here is the holding force amounting to approximately 0.95 kg (force ~9.34 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.

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 18 mm. 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 rare earth magnets.

Benefits

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

Their power remains stable, and after around 10 years it drops only by ~1% (according to research),
Neodymium magnets are characterized by highly resistant to demagnetization caused by external interference,
The use of an refined finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
Magnetic induction on the surface of the magnet remains very high,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
In view of the option of precise molding and adaptation to individualized projects, NdFeB magnets can be manufactured in a wide range of shapes and sizes, which makes them more universal,
Huge importance in innovative solutions – they serve a role in mass storage devices, electric drive systems, precision medical tools, as well as technologically advanced constructions.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Limitations

Disadvantages of neodymium magnets:

To avoid cracks under impact, we recommend using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
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 usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
Due to limitations in creating nuts and complex forms in magnets, we recommend using casing - magnetic holder.
Potential hazard resulting from small fragments of magnets pose a threat, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, tiny parts of these products can complicate diagnosis medical after entering the body.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Holding force characteristics

Maximum lifting capacity of the magnet – what contributes to it?

Holding force of 0.95 kg is a theoretical maximum value performed under specific, ideal conditions:

using a plate made of mild steel, functioning as a ideal flux conductor
with a thickness no less than 10 mm
characterized by even structure
with total lack of distance (no impurities)
under perpendicular force direction (90-degree angle)
at temperature approx. 20 degrees Celsius

Lifting capacity in practice – influencing factors

Bear in mind that the application force may be lower depending on the following factors, starting with the most relevant:

Distance (betwixt the magnet and the plate), since even a tiny clearance (e.g. 0.5 mm) leads to a drastic drop in force by up to 50% (this also applies to varnish, rust or dirt).
Force direction – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet holds much less (often approx. 20-30% of maximum force).
Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
Material composition – not every steel attracts identically. High carbon content weaken the interaction with the magnet.
Surface structure – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Roughness creates an air distance.
Heat – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).

Lifting capacity was determined with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular detachment force, in contrast under shearing force the load capacity is reduced by as much as 75%. In addition, even a slight gap between the magnet’s surface and the plate lowers the load capacity.

Warnings

Physical harm

Risk of injury: The attraction force is so great that it can result in hematomas, crushing, and broken bones. Use thick gloves.

Adults only

These products are not suitable for play. Swallowing a few magnets may result in them attracting across intestines, which poses a direct threat to life and necessitates urgent medical intervention.

Handling guide

Handle magnets with awareness. Their huge power can shock even professionals. Stay alert and respect their power.

Mechanical processing

Powder produced during machining of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.

Nickel allergy

Nickel alert: The Ni-Cu-Ni coating contains nickel. If an allergic reaction appears, cease working with magnets and wear gloves.

Do not overheat magnets

Standard neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. Damage is permanent.

Beware of splinters

NdFeB magnets are ceramic materials, meaning they are prone to chipping. Collision of two magnets will cause them shattering into shards.

Danger to pacemakers

Patients with a heart stimulator must maintain an safe separation from magnets. The magnetism can stop the functioning of the implant.

Compass and GPS

GPS units and smartphones are extremely susceptible to magnetic fields. Close proximity with a strong magnet can ruin the sensors in your phone.

Safe distance

Do not bring magnets close to a purse, laptop, or screen. The magnetic field can irreversibly ruin these devices and erase data from cards.
