Pulling power weakens drastically with every mm of spacing. Remember that even a very thin break (e.g., contamination, paint, veneer) significantly weakens the grip. Magnets operate most effectively in perfect adhesion; distance kills the force. Notice how flashily the load capacity drop, when the product does not touch tightly to the steel surface. When calculating the mounting, avoid redundant distances.

Table 2: Slippage capacity (vertical surface)

The table below calculates the theoretical holding capacity necessary to cause the slippage of the magnet vertically on a upright steel plate (assuming typical friction). This value is a function of the distance between the magnet and the surface.

Table 3: Vertical assembly (sliding) - vertical pull
MW 9x3 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.58 kg / 1.28 pounds 582.0 g / 5.7 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.39 kg / 0.86 pounds 388.0 g / 3.8 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.19 kg / 0.43 pounds 194.0 g / 1.9 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.97 kg / 2.14 pounds 970.0 g / 9.5 N

When hanging a magnet on a upright plane (e.g., a board), it you can count on only approx. 1/5 of its nominal power. Gravity as well as a weak degree of grip cause that products move down faster than they pull off. Planning a hanger? Note that the shear force is significantly lower than the perpendicular breakaway force. On a painted metal, the element will slip down under a significantly smaller load. Application of an anti-slip coating can drastically increase the grip.

A thin sheet is incapable of focus the entire magnetic field, which weakens actual performance of the holder. If you install a neodymium to a too thin substrate, the magnetism will penetrate right through and the holding will be smaller. To utilize full efficiency of this magnet's potential, you require a sufficiently solid backing of steel. The saturation effect causes that on thin elements (e.g., car bodies), the magnet shows lower pull force. We suggest choosing the steel cross-section according to the table below.

Table 5: Thermal resistance (stability) - power drop
MW 9x3 / N38

Ambient temp. (°C)	Power loss	Remaining pull (kg/lbs/g/N)	Status

40 °C	-2.2%	1.90 kg / 4.18 pounds 1897.3 g / 18.6 N	OK
60 °C	-4.4%	1.85 kg / 4.09 pounds 1854.6 g / 18.2 N

100 °C	-28.8%	1.38 kg / 3.05 pounds 1381.3 g / 13.6 N

Ordinary NdFeB products lose power after exceeding the maximum temperature. Watch out for overheating – excessive heat can irreversibly demagnetize this magnet. As the temperature rises, the neodymium's power briefly drops. Avoid using this product close to ovens higher than its operating temperature limit. Exceeding the critical threshold will result in permanent loss of magnetic properties.

*Engineering note: Heat tolerance is determined by both grade, and the Permeance Coefficient Pc. Thin magnets (pancake types) may lose charge permanently sooner than long magnets. The danger warning in the table points to permanent field degradation for this particular item.

Two magnets interact from a significantly greater distance than a neodymium and metal combination. Such a system of magnet-to-magnet generates a stronger field and a larger range of performance. Want to build a strong closure? Utilize two neodymiums instead of one magnet and a steel. Remember that when bringing together two magnets, the collision energy is extreme. The levitation is marginally weaker than the attraction, but still large.
*Field value between like poles reaches ~0 Gs in the exact middle of the gap (due to field cancellation).
* Calculations apply to friction force of two identical neodymium magnets (friction ~0.15 for Ni-Ni layer).

Extremely neodym field is a serious hazard to electronic devices and medical implants. These NdFeB products produce a flux that disrupts operation of sensitive medical devices. Remember: the invisible magnetic field passes through tissues and housings. Exceptional care must be taken by people with hearing aids and insulin pumps. Also at risk are: mechanical watches, remotes, membranes, and displays. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Neodymium magnets are very brittle – a strong collision with metal risks their cracking. Watch the impact speed – a magnet released freely turns into a projectile. Impact energy can cause material chips or injury to skin. Hold the magnet firmly during mounting so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h means shattering of the magnet. Use safety goggles when working with large magnets.

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

1. Sliding resistance

*Warning: On a vertical surface, the magnet holds only a fraction of its perpendicular strength.

2. Plate thickness effect

*Thin metal sheet (e.g. computer case) significantly reduces the holding force.

3. Temperature resistance

*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) = 0.44

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.

This product is an incredibly powerful rod magnet, composed of advanced NdFeB material, which, with dimensions of Ø9x3 mm, guarantees optimal power. This specific item features high dimensional repeatability and professional build quality, making it a perfect solution for the most demanding engineers and designers. As a cylindrical magnet with impressive force (approx. 1.94 kg), this product is available off-the-shelf from our European logistics center, ensuring lightning-fast order fulfillment. Additionally, its Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

It successfully proves itself in modeling, advanced automation, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 18.99 N with a weight of only 1.43 g, this cylindrical magnet is indispensable in miniature devices and wherever low weight is crucial.

Due to the delicate structure of the ceramic sinter, we absolutely advise against force-fitting (so-called press-fit), as this risks chipping the coating of this precision component. To ensure stability in automation, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.

Grade N38 is the most popular standard for professional neodymium magnets, offering an optimal price-to-power ratio and operational stability. If you need even stronger magnets in the same volume (Ø9x3), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.

The presented product is a neodymium magnet with precisely defined parameters: diameter 9 mm and height 3 mm. The value of 18.99 N means that the magnet is capable of holding a weight many times exceeding its own mass of 1.43 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 3 mm), which means that the N and S poles are located on the flat, circular surfaces. 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.

Advantages as well as disadvantages of Nd₂Fe₁₄B magnets.

Strengths

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

They retain full power for almost 10 years – the loss is just ~1% (in theory),
Neodymium magnets remain highly resistant to magnetic field loss caused by external magnetic fields,
A magnet with a smooth gold surface has an effective appearance,
They are known for high magnetic induction at the operating surface, making them more effective,
Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for operation at temperatures approaching 230°C and above...
Possibility of custom modeling and adjusting to specific requirements,
Versatile presence in modern technologies – they are used in hard drives, drive modules, medical devices, and other advanced devices.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Disadvantages

What to avoid - cons of neodymium magnets: weaknesses and usage proposals

They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also increases its resistance to damage
When exposed to high temperature, neodymium magnets experience 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
Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
We recommend a housing - magnetic mechanism, due to difficulties in realizing threads inside the magnet and complicated forms.
Possible danger to health – tiny shards of magnets pose a threat, when accidentally swallowed, which becomes key 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 have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities

Pull force analysis

Detachment force of the magnet in optimal conditions – what it depends on?

Holding force of 1.94 kg is a measurement result conducted under specific, ideal conditions:

on a plate made of structural steel, perfectly concentrating the magnetic flux
possessing a massiveness of minimum 10 mm to avoid saturation
with a surface cleaned and smooth
with direct contact (no paint)
for force applied at a right angle (pull-off, not shear)
at temperature room level

Determinants of lifting force in real conditions

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

Gap (between the magnet and the metal), since even a microscopic distance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to varnish, corrosion or dirt).
Load vector – maximum parameter is available only during perpendicular pulling. The shear force of the magnet along the surface is usually several times lower (approx. 1/5 of the lifting capacity).
Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
Chemical composition of the base – low-carbon steel gives the best results. Alloy admixtures lower magnetic properties and holding force.
Plate texture – smooth surfaces guarantee perfect abutment, which improves force. Rough surfaces reduce efficiency.
Temperature – heating the magnet results in weakening of force. It is worth remembering the maximum operating temperature for a given model.

Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under attempts to slide the magnet 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 holding force.

Precautions when working with NdFeB magnets

Demagnetization risk

Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will permanently weaken its properties and pulling force.

Danger to the youngest

Strictly store magnets away from children. Choking hazard is significant, and the effects of magnets connecting inside the body are very dangerous.

Avoid contact if allergic

Nickel alert: The nickel-copper-nickel coating consists of nickel. If skin irritation appears, immediately stop handling magnets and wear gloves.

Medical interference

Patients with a pacemaker should keep an safe separation from magnets. The magnetism can interfere with the functioning of the life-saving device.

Dust is flammable

Dust generated during machining of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.

Handling guide

Use magnets consciously. Their immense force can surprise even experienced users. Plan your moves and do not underestimate their power.

Risk of cracking

Despite the nickel coating, the material is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.

GPS Danger

A powerful magnetic field negatively affects the operation of compasses in smartphones and navigation systems. Keep magnets close to a smartphone to prevent breaking the sensors.

Pinching danger

Danger of trauma: The pulling power is so great that it can result in hematomas, pinching, and broken bones. Protective gloves are recommended.

Threat to electronics

Intense magnetic fields can destroy records on credit cards, HDDs, and other magnetic media. Keep a distance of at least 10 cm.
