Pulling power decreases sharply per each millimeter of distance. Note that even a very thin break (e.g., contamination, varnish, rust) strongly diminishes the holding power. Magnets work strongest in perfect adhesion; gap weakens the power. See how rapidly the parameters fall, when the magnet does not adhere directly to the metal substrate. When calculating the assembly, discard additional spacers.

This section shows the theoretical holding capacity sufficient to start the shifting of the magnet down against a vertical metal surface (considering standard friction). The holding force varies with the gap size between the magnet and the metal.

When mounting a holder on a upright surface (e.g., a fridge), it you can count on just about 20%-30% of its nominal power. Gravitational force as well as a weak degree of grip cause that products move down faster than they pull off. Planning a wall mount? Note that the shear force is noticeably lower than the perpendicular breakaway force. On a smooth steel, the magnet will slip down under a noticeably lighter weight. Using a rubber pad can effectively improve the result.

A thin metal plate cannot conduct the full magnetic flux, which weakens actual performance of the magnet. Should you mount a strong magnet to a thin surface, the magnetism will pass right through and the pull force will drop sharply. To squeeze the maximum of this neodymium's power, you require a sufficiently solid element of steel. The material oversaturation means that on delicate walls (e.g., thin profiles), the holder holds weaker. We advise picking the steel cross-section based on the following data.

Standard neodymium magnets change their properties power past the thermal threshold. Watch out for overheating – high temperature can permanently damage this product. With every degree above norm, the magnet's force momentarily drops. Avoid using this magnet in hot environments exceeding its operating temperature limit. Ignoring the limit will result in destruction of magnetic properties.

*Engineering note: Thermal stability depends not only on the material grade, and the Permeance Coefficient Pc. Low-profile magnets (pancake types) may lose charge permanently under lower heat stress than long magnets. Warning indicator in the table signals permanent field degradation for this specific geometry.

Two magnetic products interact from a wider radius than a magnet and steel setup. The connection of magnet-to-magnet generates a stronger field and a larger range of action. Designing a solid fastener? Utilize two neodymiums instead of a neodymium and a striker plate. Be careful that when connecting a pair of magnets, the impact force is huge. The repulsion force is a bit weaker than the connection force, but still significant.
*Field value between like poles drops to ~0 Gs at the geometric center of the gap (due to field cancellation).
Note: Calculations demonstrate sliding force of two same magnets (friction coefficient ~0.15 for Ni-Ni layer).

Powerful magnet radiation poses a real danger to electronics and medical implants. These neodymiums generate a field that prevents correct functioning of digital equipment. Be aware: the unseen radiation passes through tissues and glass. Special caution must be exercised by people with cochlear implants and drug dispensers. Influence will be felt by: mechanical watches, car keys, membranes, and displays. Do not bring the product near payment cards, HDD media, or precise measuring instruments.

NdFeB products are delicate – a collision with steel risks their cracking. Pay attention to connection velocity – a magnet released freely speeds with massive force. Striking energy can trigger coating fragments or dangerous crushing to fingers. Be sure to control the product 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. Use safety goggles when handling with large magnets.

The magnetic field penetrates through water without any losses. Buoyancy helps in lifting finds.

1. Shear force

*Note: On a vertical wall, the magnet holds just a fraction of its nominal pull.

2. Plate thickness effect

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

3. Thermal stability

*For N38 grade, 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) = 0.68

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 extremely powerful cylinder magnet, composed of advanced NdFeB material, which, at dimensions of Ø8x5 mm, guarantees optimal power. The MW 8x5 / N38 model is characterized by high dimensional repeatability and industrial build quality, making it an excellent solution for professional engineers and designers. As a magnetic rod with significant force (approx. 2.17 kg), this product is available off-the-shelf from our European logistics center, ensuring rapid order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating shields it against corrosion in standard 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 21.31 N with a weight of only 1.88 g, this cylindrical magnet is indispensable in miniature devices and wherever every gram matters.

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 professional component. To ensure long-term durability in automation, 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 suitable for the majority of applications in automation and machine building, where extreme miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø8x5), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.

This model is characterized by dimensions Ø8x5 mm, which, at a weight of 1.88 g, makes it an element with high magnetic energy density. The key parameter here is the holding force amounting to approximately 2.17 kg (force ~21.31 N), which, with such defined dimensions, proves the high grade of the NdFeB material. 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 8 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 through the diameter if your project requires it.

Strengths as well as weaknesses of neodymium magnets.

Benefits

Besides their high retention, neodymium magnets are valued for these benefits:

They do not lose strength, even during nearly ten years – the drop in strength is only ~1% (theoretically),
They possess excellent resistance to magnetic field loss due to external magnetic sources,
Thanks to the shimmering finish, the layer of nickel, gold-plated, or silver-plated gives an aesthetic appearance,
Magnetic induction on the working part of the magnet turns out to be exceptional,
Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
Thanks to modularity in constructing and the capacity to customize to client solutions,
Versatile presence in future technologies – they serve a role in mass storage devices, drive modules, medical equipment, also complex engineering applications.
Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,

Cons

Disadvantages of NdFeB magnets:

At strong impacts they can break, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
We recommend a housing - magnetic holder, due to difficulties in creating threads inside the magnet and complex shapes.
Potential hazard to health – tiny shards of magnets can be dangerous, if swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small elements of these magnets can disrupt the diagnostic process medical after entering the body.
Due to complex production process, their price is higher than average,

Lifting parameters

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

The declared magnet strength refers to the peak performance, recorded under laboratory conditions, namely:

using a base made of low-carbon steel, acting as a circuit closing element
with a thickness no less than 10 mm
with a plane perfectly flat
without the slightest insulating layer between the magnet and steel
during detachment in a direction perpendicular to the mounting surface
in neutral thermal conditions

Magnet lifting force in use – key factors

It is worth knowing that the working load may be lower subject to elements below, starting with the most relevant:

Clearance – the presence of any layer (rust, tape, air) interrupts the magnetic circuit, which reduces capacity steeply (even by 50% at 0.5 mm).
Force direction – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
Material composition – different alloys reacts the same. Alloy additives weaken the attraction effect.
Smoothness – full contact is obtained only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
Heat – neodymium magnets have a sensitivity to temperature. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).

Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, whereas under parallel forces the holding force is lower. Moreover, even a small distance between the magnet and the plate lowers the holding force.

H&S for magnets

Permanent damage

Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and strength.

Threat to navigation

Be aware: rare earth magnets generate a field that confuses precision electronics. Maintain a separation from your mobile, device, and navigation systems.

Machining danger

Powder generated during cutting of magnets is flammable. Do not drill into magnets unless you are an expert.

Conscious usage

Handle with care. Neodymium magnets act from a long distance and connect with massive power, often faster than you can move away.

Serious injuries

Big blocks can smash fingers in a fraction of a second. Under no circumstances put your hand betwixt two strong magnets.

Pacemakers

People with a ICD must maintain an safe separation from magnets. The magnetic field can stop the functioning of the implant.

Product not for children

Neodymium magnets are not suitable for play. Swallowing multiple magnets may result in them connecting inside the digestive tract, which constitutes a direct threat to life and requires immediate surgery.

Nickel coating and allergies

Nickel alert: The nickel-copper-nickel coating consists of nickel. If an allergic reaction occurs, immediately stop handling magnets and use protective gear.

Electronic devices

Intense magnetic fields can corrupt files on payment cards, HDDs, and other magnetic media. Keep a distance of at least 10 cm.

Shattering risk

Neodymium magnets are ceramic materials, meaning they are prone to chipping. Collision of two magnets leads to them breaking into small pieces.
