Grip strength drops drastically with every mm of gap. Keep in mind that even the smallest gap (e.g., contamination, varnish, veneer) strongly weakens the grip. Magnets operate strongest during direct contact; air break drastically cuts the force. Notice how quickly the load capacity plummet, when the magnet does not touch directly to the metal substrate. When calculating the mounting, discard unnecessary gaps.

This section shows the approximate force needed to cause the sliding of the magnet down along a upright steel wall (assuming standard friction). This parameter varies with the separation distance between the magnet and the metal.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
MW 50x20 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	21.03 kg / 46.36 pounds 21030.0 g / 206.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	14.02 kg / 30.91 pounds 14020.0 g / 137.5 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	7.01 kg / 15.45 pounds 7010.0 g / 68.8 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	35.05 kg / 77.27 pounds 35050.0 g / 343.8 N

When mounting a holder on a upright wall (e.g., a car body), it will only hold just approx. 1/5 of nominal attraction strength. Gravitational force and a low friction coefficient mean that holders slide down easier than they pull off. Planning a vertical fastening? Consider that the shear force is significantly lower than the perpendicular breakaway force. On a smooth steel, the holder will slide down under a noticeably lighter cargo. Using a rubber layer can significantly improve the result.

12 mm	100%	70.10 kg / 154.54 pounds 70100.0 g / 687.7 N

A thin sheet is incapable of focus the full magnetic flux, which wastes potential of the magnet. Should you attach a powerful product to a too thin substrate, the magnetism will penetrate right through and the pull force will drop sharply. To squeeze the maximum of this magnet's potential, you require a sufficiently solid backing of metal. The saturation phenomenon causes that on thin elements (e.g., car bodies), the holder shows lower pull force. We suggest choosing the steel thickness based on the following data.

Standard neodymium magnets lose power after exceeding the maximum temperature. Watch out for overheating – excessive heat can irreversibly destroy this product. As the temperature rises, the magnet's power briefly lowers. Do not use this product near heat sources higher than its safe range. Exceeding the critical threshold will result in destruction of magnetic properties.

*Important note: Heat tolerance is determined by both grade, and the Permeance Coefficient Pc. Flat magnets (low Pc) risk losing magnetic properties at lower temperatures compared to rod magnets. Warning indicator in the table points to permanent field degradation for this particular item.

Two magnetic products attract each other from a much further distance than a magnet and sheet setup. The setup of two magnets produces a massive flux and a larger range of performance. Designing a powerful holder? Utilize two neodymiums instead of one magnet and a steel. Remember that when bringing together two magnets, the pinch force is extreme. The levitation is marginally weaker than the attraction, but still large.
*Flux density in repulsion mode reaches ~0 Gs at the midpoint of the gap (caused by magnetic field nullification).
Note: Figures refer to sliding force of a pair of same neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

A strong magnetic field poses a large risk to electronics and medical implants. These NdFeB products produce a flux that destroys function of digital equipment. Notice: the invisible magnetic field passes through tissues and plastic. Increased vigilance must be taken by people with cochlear implants and drug dispensers. Also at risk are: mechanical watches, car keys, membranes, and screens. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

Magnetic elements are delicate – a violent impact against metal can result in shattering. Pay attention to connection velocity – a magnet released freely becomes dangerous. Kinetic force can destroy the magnet or injury to skin. Always hold the magnet during installation so it doesn't hit violently against the metal. A contact at a velocity of dozens of km/h ends with a crack of the neodymium. Wear eye protection when working with powerful specimens.

Warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

Contrary to myths, water does not block the magnetic field. Buoyancy helps in lifting finds.

1. Shear force

*Warning: On a vertical surface, the magnet retains just approx. 20-30% of its max power.

2. Steel saturation

*Thin metal sheet (e.g. computer case) severely weakens the holding force.

3. Power loss vs temp

*For standard magnets, the safety limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.50

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 offered product is an exceptionally strong rod magnet, manufactured from modern NdFeB material, which, with dimensions of Ø50x20 mm, guarantees the highest energy density. The MW 50x20 / N38 component features high dimensional repeatability and professional build quality, making it an excellent solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 70.10 kg), this product is available off-the-shelf from our European logistics center, ensuring quick 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 finds application in DIY projects, advanced robotics, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 687.66 N with a weight of only 294.52 g, this rod is indispensable in electronics and wherever every gram matters.

Since our magnets have a very precise dimensions, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 50.1 mm) using epoxy glues. To ensure stability in industry, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.

Grade N38 is the most frequently chosen standard for industrial neodymium magnets, offering an optimal price-to-power ratio and operational stability. If you need the strongest magnets in the same volume (Ø50x20), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.

The presented product is a neodymium magnet with precisely defined parameters: diameter 50 mm and height 20 mm. The value of 687.66 N means that the magnet is capable of holding a weight many times exceeding its own mass of 294.52 g. The product has a [NiCuNi] coating, which secures it 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 50 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.

Pros and cons of neodymium magnets.

Benefits

In addition to their pulling strength, neodymium magnets provide the following advantages:

They retain full power for nearly ten years – the loss is just ~1% (based on simulations),
They retain their magnetic properties even under close interference source,
In other words, due to the metallic layer of silver, the element gains visual value,
Neodymium magnets deliver maximum magnetic induction on a contact point, which increases force concentration,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
Possibility of custom forming and modifying to concrete requirements,
Significant place in advanced technology sectors – they serve a role in magnetic memories, brushless drives, precision medical tools, as well as other advanced devices.
Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which makes them useful in miniature devices

Limitations

Characteristics of disadvantages of neodymium magnets: tips and applications.

To avoid cracks under impact, we recommend using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
Magnets exposed to a humid environment can rust. Therefore while using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
Limited possibility of creating threads in the magnet and complicated forms - recommended is cover - mounting mechanism.
Health risk resulting from small fragments of magnets pose a threat, if swallowed, which becomes key in the aspect of protecting the youngest. Additionally, tiny parts of these magnets can disrupt the diagnostic process medical after entering the body.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Holding force characteristics

Maximum lifting capacity of the magnet – what it depends on?

The lifting capacity listed is a theoretical maximum value conducted under specific, ideal conditions:

using a plate made of mild steel, acting as a circuit closing element
whose transverse dimension reaches at least 10 mm
characterized by even structure
under conditions of gap-free contact (metal-to-metal)
under axial force direction (90-degree angle)
in neutral thermal conditions

Practical lifting capacity: influencing factors

During everyday use, the actual lifting capacity depends on several key aspects, presented from crucial:

Clearance – existence of foreign body (rust, tape, air) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
Loading method – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet holds significantly lower power (typically approx. 20-30% of maximum force).
Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
Plate material – mild steel attracts best. Alloy admixtures reduce magnetic properties and lifting capacity.
Base smoothness – the more even the plate, the larger the contact zone and higher the lifting capacity. Roughness acts like micro-gaps.
Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, in contrast under shearing force the holding force is lower. Additionally, even a slight gap between the magnet’s surface and the plate reduces the holding force.

Precautions when working with neodymium magnets

Warning for heart patients

People with a pacemaker should keep an large gap from magnets. The magnetism can stop the operation of the implant.

Dust explosion hazard

Mechanical processing of NdFeB material carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is difficult to extinguish.

Danger to the youngest

Absolutely store magnets out of reach of children. Choking hazard is significant, and the effects of magnets connecting inside the body are very dangerous.

Caution required

Exercise caution. Neodymium magnets attract from a long distance and snap with huge force, often quicker than you can move away.

Eye protection

Neodymium magnets are ceramic materials, meaning they are prone to chipping. Clashing of two magnets will cause them cracking into shards.

Keep away from electronics

Be aware: neodymium magnets generate a field that interferes with precision electronics. Maintain a separation from your mobile, device, and navigation systems.

Maximum temperature

Standard neodymium magnets (grade N) lose magnetization when the temperature goes above 80°C. This process is irreversible.

Finger safety

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

Nickel coating and allergies

Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If an allergic reaction appears, cease working with magnets and wear gloves.
