Magnetic force weakens sharply with every subsequent millimeter of distance. Remember that even a very thin break (e.g., dirt, varnish, rust) significantly diminishes the holding power. Magnets work strongest during direct contact; distance weakens the power. Notice how quickly the parameters plummet, when the magnet does not touch tightly to the steel surface. When calculating the assembly, discard unnecessary gaps.

The following data presents the estimated holding capacity sufficient to cause the slippage of the magnet downwards along a vertical metal surface (assuming typical friction coefficient). This parameter varies with the separation distance between the magnet and the metal.

Table 3: Vertical assembly (shearing) - behavior on slippery surfaces

Raw steel	µ = 0.3 30% Nominalnej Siły	9.84 kg / 21.69 lbs 9837.0 g / 96.5 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	6.56 kg / 14.46 lbs 6558.0 g / 64.3 N

Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	16.40 kg / 36.14 lbs 16395.0 g / 160.8 N

When placing a holder on a vertical wall (e.g., a board), it will only hold just about 1/5 of nominal attraction strength. Gravity as well as a weak degree of grip cause that products slip easier than they pop off the substrate. Planning a hanger? Note that the sliding force is noticeably lower than the maximum static pull force. On a slippery surface, the element will slide down under a significantly smaller cargo. Using a rubber layer can drastically improve the result.

A too thin steel is not enough to take in the entire magnetic field, which weakens actual performance of the holder. If you attach a powerful product to a too thin substrate, the field will penetrate right through and the attraction force will be weaker. To utilize the maximum of this magnet's potential, you need a suitably thick backing of steel. The material oversaturation means that on thin elements (e.g., thin profiles), the magnet works worse. We recommend selecting the steel dimension based on the following data.

Ordinary NdFeB products irreversibly lose power past the thermal threshold. Avoid high temperatures – high temperature can irreversibly destroy this product. With every degree above norm, the magnet's force briefly drops. Avoid using this product near heat sources higher than its working range. Exceeding the critical threshold will lead to permanent loss of magnetism.

*Important note: Thermal stability depends not only on the material grade, but also on the magnet's shape. Flat magnets (pancake types) are more susceptible to demagnetization sooner compared to rod magnets. The danger warning in the table signals permanent field degradation for this particular item.

Two strong neodymiums interact from a much further distance than a magnet and steel combination. Such a system of two magnets generates a stronger field and a larger range of operation. Designing a powerful holder? Apply two magnets instead of one magnet and a steel. Be careful that when connecting a pair of magnets, the impact force is massive. The levitation is a bit weaker than the attraction, but still large.
*The magnetic induction between like poles is approximately ~0 Gs at the geometric center of the gap (due to field cancellation).
Note: Estimates refer to sliding force of a pair of matching magnets (friction ~0.15 for Ni-Ni layer).

Powerful magnet radiation is a large risk to IT equipment and pacemakers. These neodymiums produce a field that disrupts operation of digital equipment. Be aware: the unseen radiation acts through matter and plastic. Special caution must be exercised by people with cochlear implants and insulin pumps. Also at risk are: automatic timepieces, car keys, speakers, and displays. Avoid contact with magnetic cards, HDD media, or sensitive navigation tools.

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	21.17 km/h (5.88 m/s)	1.76 J
30 mm	31.61 km/h (8.78 m/s)	3.93 J

100 mm	57.16 km/h (15.88 m/s)	12.87 J

Magnetic elements are delicate – a violent impact against metal causes immediate chipping. Control the attraction moment – a neodymium left loose becomes dangerous. Kinetic force can cause material chips or injury to fingers. Hold the magnet firmly during mounting so it doesn't hit violently against the steel surface. A collision at high speed almost guarantees destruction of the magnet. Wear eye protection when handling with powerful specimens.

Corrosion 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. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Wall mount (shear)

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

2. Plate thickness effect

*Thin metal sheet (e.g. computer case) drastically limits 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) = 0.42

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.

This product is a very strong cylinder magnet, produced from modern NdFeB material, which, with dimensions of Ø38x12 mm, guarantees maximum efficiency. This specific item boasts an accuracy of ±0.1mm and industrial build quality, making it an excellent solution for the most demanding engineers and designers. As a magnetic rod with impressive force (approx. 32.79 kg), this product is in stock from our European logistics center, ensuring rapid order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

It successfully proves itself in modeling, advanced robotics, and broadly understood industry, serving as a fastening or actuating element. Thanks to the high power of 321.71 N with a weight of only 102.07 g, this cylindrical magnet is indispensable in miniature devices and wherever low weight is crucial.

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 stability in industry, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.

Magnets NdFeB grade N38 are strong enough 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 (Ø38x12), 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 Ø38x12 mm, which, at a weight of 102.07 g, makes it an element with high magnetic energy density. The value of 321.71 N means that the magnet is capable of holding a weight many times exceeding its own mass of 102.07 g. The product has a [NiCuNi] coating, which secures it 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 38 mm. 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.

Pros and cons of rare earth magnets.

Benefits

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

Their power remains stable, and after approximately 10 years it decreases only by ~1% (according to research),
They are resistant to demagnetization induced by external field influence,
A magnet with a metallic silver surface has an effective appearance,
The surface of neodymium magnets generates a powerful magnetic field – this is one of their assets,
Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
Possibility of detailed modeling and optimizing to precise applications,
Fundamental importance in modern technologies – they are utilized in data components, electromotive mechanisms, medical devices, as well as complex engineering applications.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Cons

Cons of neodymium magnets: tips and applications.

At very strong impacts they can break, therefore we advise placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (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 rust in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
We recommend cover - magnetic holder, due to difficulties in creating nuts inside the magnet and complex forms.
Potential hazard to health – tiny shards of magnets can be dangerous, in case of ingestion, which gains importance in the aspect of protecting the youngest. Additionally, tiny parts of these products are able to disrupt the diagnostic process medical in case of swallowing.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Lifting parameters

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

Holding force of 32.79 kg is a result of laboratory testing executed under the following configuration:

with the application of a yoke made of low-carbon steel, ensuring maximum field concentration
whose transverse dimension equals approx. 10 mm
with a surface cleaned and smooth
without any clearance between the magnet and steel
for force applied at a right angle (in the magnet axis)
at standard ambient temperature

Lifting capacity in practice – influencing factors

During everyday use, the real power depends on a number of factors, presented from crucial:

Distance – existence of any layer (paint, dirt, air) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the maximum value.
Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
Plate material – mild steel attracts best. Alloy steels reduce magnetic properties and holding force.
Plate texture – smooth surfaces ensure maximum contact, which improves force. Uneven metal reduce efficiency.
Operating temperature – neodymium magnets have a sensitivity to temperature. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity testing was carried out on a smooth plate of optimal thickness, under perpendicular forces, however under parallel forces the holding force is lower. Moreover, even a slight gap between the magnet and the plate decreases the holding force.

Safety rules for work with NdFeB magnets

Life threat

People with a ICD must maintain an absolute distance from magnets. The magnetism can stop the functioning of the implant.

Magnetic media

Very strong magnetic fields can corrupt files on payment cards, hard drives, and storage devices. Stay away of min. 10 cm.

Nickel allergy

A percentage of the population suffer from a hypersensitivity to Ni, which is the common plating for neodymium magnets. Frequent touching might lead to an allergic reaction. We suggest use safety gloves.

Dust explosion hazard

Machining of neodymium magnets poses a fire risk. Neodymium dust reacts violently with oxygen and is hard to extinguish.

Bodily injuries

Big blocks can smash fingers instantly. Under no circumstances place your hand betwixt two strong magnets.

Safe operation

Handle with care. Rare earth magnets attract from a distance and connect with massive power, often quicker than you can move away.

Thermal limits

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

GPS and phone interference

An intense magnetic field negatively affects the functioning of magnetometers in smartphones and GPS navigation. Do not bring magnets near a smartphone to avoid damaging the sensors.

Fragile material

Neodymium magnets are ceramic materials, meaning they are fragile like glass. Collision of two magnets leads to them shattering into shards.
