Grip strength drops sharply per each millimeter of distance. Keep in mind that even a microscopic distance (e.g., contamination, paint, rust) noticeably diminishes the holding power. Neodymiums hold strongest during direct contact; gap kills the force. Notice how quickly the load capacity plummet, when the magnet does not touch tightly to the metal substrate. When planning the arrangement, avoid unnecessary gaps.

This section indicates the approximate shear load sufficient to initiate the sliding of the magnet vertically on a vertical metal surface (considering standard friction coefficient). This parameter varies with the distance between the magnet and the metal.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
MW 12x4 / N52

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	1.40 kg / 3.10 LBS 1404.0 g / 13.8 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.94 kg / 2.06 LBS 936.0 g / 9.2 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.47 kg / 1.03 LBS 468.0 g / 4.6 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	2.34 kg / 5.16 LBS 2340.0 g / 23.0 N

When hanging a magnet on a upright surface (e.g., a car body), it you can count on only approx. 1/5 of its maximum pull force. Gravitational force as well as a low friction coefficient influence the fact that holders slip faster than they pull off. Designing a vertical fastening? Consider that the sliding force is significantly lower than the perpendicular breakaway force. On a painted metal, the element will slide down under a significantly smaller cargo. Using a rubber layer can effectively raise the stability.

A too thin steel cannot absorb the full magnetic flux, which weakens actual performance of the holder. If you attach a powerful product to a weak sheet, the flux will pass right through and the attraction force will be weaker. To utilize 100% of this neodymium's power, you need a suitably thick piece of metal. The saturation effect means that on thin elements (e.g., thin profiles), the product shows lower pull force. We advise picking the steel dimension from these parameters.

Ordinary NdFeB products irreversibly lose strength after exceeding the maximum temperature. Protect against heat – excessive heat can permanently demagnetize this product. As the temperature rises, the magnet's power temporarily decreases. Refrain from using this product close to heaters higher than its working range. Ignoring the limit will cause irreversible degradation of magnetic properties.

*Important note: Temperature resistance depends not only on the material grade, as well as the dimension ratios. Thin magnets (low Pc) risk losing magnetic properties under lower heat stress than taller cylinders. Warning indicator in the table indicates permanent field degradation for this specific geometry.

Two magnets attract each other from a wider radius than a magnet and steel setup. The connection of magnet-to-magnet creates a more powerful interaction and a larger range of performance. Planning to create a solid fastener? Use a pair of magnets instead of a neodymium and a steel. Be careful that when bringing together two magnets, the impact force is huge. The levitation is marginally weaker than the connection force, but still significant.
*The magnetic induction between like poles drops to ~0 Gs in the exact middle between the magnets (due to field cancellation).
Important: Calculations refer to shear force of two matching magnets (friction ~0.15 for Ni-Ni layer).

Powerful magnet radiation poses a large risk to electronic devices and pacemakers. These NdFeB products generate a flux that destroys function of sensitive medical devices. Remember: the invisible magnetic field penetrates the body and housings. Exceptional care must be exercised by people with hearing aids and drug dispensers. Also at risk are: automatic timepieces, remotes, speakers, and displays. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

Magnetic elements are very brittle – a collision with steel risks their cracking. Pay attention to connection velocity – a neodymium left loose speeds with massive force. Striking energy can destroy the magnet or injury to fingers. Hold the magnet firmly during mounting so it doesn't hit violently against the metal. A contact at a velocity of dozens of km/h almost guarantees destruction of the neodymium. Wear eye protection when handling 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!

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. Shear force

*Note: On a vertical wall, the magnet holds merely a fraction of its perpendicular strength.

2. Steel saturation

*Thin metal sheet (e.g. computer case) significantly weakens 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) = 0.44

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.

The presented product is an extremely powerful rod magnet, produced from modern NdFeB material, which, with dimensions of Ø12x4 mm, guarantees optimal power. This specific item boasts an accuracy of ±0.1mm and professional build quality, making it a perfect solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 4.68 kg), this product is in stock from our European logistics center, ensuring quick order fulfillment. Furthermore, its Ni-Cu-Ni coating effectively protects it against corrosion in standard 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 positioning or actuating element. Thanks to the pull force of 45.89 N with a weight of only 3.39 g, this cylindrical magnet is indispensable in electronics and wherever every gram matters.

Due to the brittleness of the NdFeB material, you must not use force-fitting (so-called press-fit), as this risks immediate cracking 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 industrial neodymium magnets, offering a great economic balance and high resistance to demagnetization. If you need the strongest magnets in the same volume (Ø12x4), 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 Ø12x4 mm, which, at a weight of 3.39 g, makes it an element with high magnetic energy density. The value of 45.89 N means that the magnet is capable of holding a weight many times exceeding its own mass of 3.39 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 12 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.

Strengths as well as weaknesses of rare earth magnets.

Advantages

Besides their magnetic performance, neodymium magnets are valued for these benefits:

They have stable power, and over more than ten years their performance decreases symbolically – ~1% (in testing),
They maintain their magnetic properties even under external field action,
By covering with a decorative coating of nickel, the element has an professional look,
They show high magnetic induction at the operating surface, which improves attraction properties,
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...
Thanks to freedom in designing and the ability to modify to specific needs,
Versatile presence in modern industrial fields – they are utilized in computer drives, brushless drives, precision medical tools, as well as other advanced devices.
Thanks to their power density, small magnets offer high operating force, occupying minimum space,

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 shields the magnet but also improves its resistance to damage
Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (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
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
Due to limitations in realizing nuts and complicated shapes in magnets, we recommend using cover - magnetic mechanism.
Health risk related to microscopic parts of magnets pose a threat, in case of ingestion, which becomes key in the aspect of protecting the youngest. Furthermore, small elements of these devices 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

Lifting parameters

Maximum magnetic pulling force – what contributes to it?

The force parameter is a theoretical maximum value executed under the following configuration:

with the use of a sheet made of low-carbon steel, guaranteeing maximum field concentration
with a thickness minimum 10 mm
characterized by lack of roughness
without the slightest air gap between the magnet and steel
during detachment in a direction perpendicular to the mounting surface
in stable room temperature

Lifting capacity in real conditions – factors

In practice, the actual holding force depends on several key aspects, listed from the most important:

Distance – existence of any layer (rust, dirt, air) interrupts the magnetic circuit, which reduces capacity steeply (even by 50% at 0.5 mm).
Force direction – declared lifting capacity refers to detachment vertically. When slipping, the magnet holds much less (typically approx. 20-30% of nominal force).
Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of generating force.
Steel type – mild steel attracts best. Alloy admixtures reduce magnetic permeability and lifting capacity.
Base smoothness – the more even the plate, the better the adhesion and stronger the hold. Unevenness creates an air distance.
Temperature – heating the magnet causes a temporary drop of induction. Check the thermal limit for a given model.

Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the holding force is lower. Additionally, even a slight gap between the magnet’s surface and the plate lowers the load capacity.

Safe handling of neodymium magnets

Crushing risk

Mind your fingers. Two large magnets will snap together immediately with a force of several hundred kilograms, destroying anything in their path. Exercise extreme caution!

Flammability

Fire warning: Neodymium dust is highly flammable. Do not process magnets without safety gear as this risks ignition.

Conscious usage

Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.

Nickel allergy

Medical facts indicate that the nickel plating (standard magnet coating) is a potent allergen. If you have an allergy, refrain from touching magnets with bare hands and choose versions in plastic housing.

Danger to the youngest

Only for adults. Small elements can be swallowed, leading to serious injuries. Keep away from kids and pets.

Keep away from electronics

An intense magnetic field disrupts the functioning of compasses in phones and navigation systems. Do not bring magnets near a device to prevent breaking the sensors.

Protective goggles

NdFeB magnets are ceramic materials, which means they are fragile like glass. Impact of two magnets leads to them breaking into small pieces.

Keep away from computers

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

ICD Warning

Medical warning: Neodymium magnets can deactivate pacemakers and defibrillators. Do not approach if you have electronic implants.

Heat warning

Keep cool. Neodymium magnets are sensitive to temperature. If you need resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
