Grip strength drops sharply per each millimeter of spacing. Remember that even a very thin break (e.g., contamination, varnish, veneer) significantly diminishes the holding power. Magnetic products work optimally during direct contact; gap kills the force. Analyze how rapidly the parameters drop, when the product does not touch flatly to the metal substrate. When calculating the arrangement, avoid unnecessary gaps.

The table below calculates the estimated shear load necessary to cause the sliding of the magnet vertically along a upright steel wall (assuming typical friction). This value depends on the gap size between the magnet and the surface.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
MW 38x3.5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	1.53 kg / 3.37 pounds 1527.0 g / 15.0 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.02 kg / 2.24 pounds 1018.0 g / 10.0 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.51 kg / 1.12 pounds 509.0 g / 5.0 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	2.55 kg / 5.61 pounds 2545.0 g / 25.0 N

When mounting a holder on a vertical wall (e.g., a board), it will only hold only approx. 20%-30% of its nominal power. Gravitational force as well as a low friction coefficient mean that magnets slide down faster than they detach. Want to create a vertical fastening? Remember that the shear force is much weaker than the maximum static pull force. On a slippery surface, the element will slide down under a much lighter weight. Application of an anti-slip coating can significantly improve the result.

3 mm	75%	3.82 kg / 8.42 pounds 3817.5 g / 37.4 N
5 mm	100%	5.09 kg / 11.22 pounds 5090.0 g / 49.9 N
10 mm	100%	5.09 kg / 11.22 pounds 5090.0 g / 49.9 N
11 mm	100%	5.09 kg / 11.22 pounds 5090.0 g / 49.9 N
12 mm	100%	5.09 kg / 11.22 pounds 5090.0 g / 49.9 N

A too thin steel is unable to absorb the entire magnetic field, which squanders power of the holder. If you attach a powerful product to a weak sheet, the field will penetrate right through and the pull force will drop sharply. To achieve the maximum of this neodymium's potential, you need a suitably thick piece of steel. The saturation effect causes that on sheet metal structures (e.g., car bodies), the magnet holds weaker. We advise picking the steel dimension according to the table below.

Table 5: Thermal stability (material behavior) - thermal limit
MW 38x3.5 / N38

Ambient temp. (°C)	Power loss	Remaining pull (kg/lbs/g/N)	Status
20 °C	0.0%	5.09 kg / 11.22 pounds 5090.0 g / 49.9 N	OK
40 °C	-2.2%	4.98 kg / 10.97 pounds 4978.0 g / 48.8 N	OK
60 °C	-4.4%	4.87 kg / 10.73 pounds 4866.0 g / 47.7 N
80 °C	-6.6%	4.75 kg / 10.48 pounds 4754.1 g / 46.6 N
100 °C	-28.8%	3.62 kg / 7.99 pounds 3624.1 g / 35.6 N

Standard neodymium magnets change their properties parameters past the thermal threshold. Protect against heat – heat can irreversibly destroy this magnet. As the temperature rises, the magnet's capacity momentarily decreases. Refrain from using this magnet close to heaters higher than its working range. Ignoring the limit will lead to permanent loss of magnetic properties.

*Important note: Heat tolerance is determined by both grade, and the Permeance Coefficient Pc. Thin magnets (low Pc) risk losing magnetic properties under lower heat stress than long magnets. Warning indicator in the table points to permanent field degradation for this specific geometry.

Two magnetic products attract each other from a much further distance than a neodymium and metal setup. The setup of magnet-to-magnet generates a stronger field and a wider radius of performance. Planning to create a solid fastener? Utilize two neodymiums instead of a neodymium and a steel. Remember that when connecting a pair of magnets, the collision energy is massive. The repulsion force is a bit weaker than the connection force, but still impressive.
*Flux density between like poles is approximately ~0 Gs in the exact middle between the magnets (caused by magnetic field nullification).
Attention: Figures refer to shear force of a pair of same neodymium magnets (friction ~0.15 for Ni-Ni coating).

Table 7: Hazards (electronics) - warnings
MW 38x3.5 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	11.5 cm
Hearing aid	10 Gs (1.0 mT)	9.0 cm
Mechanical watch	20 Gs (2.0 mT)	7.0 cm
Mobile device	40 Gs (4.0 mT)	5.5 cm
Car key	50 Gs (5.0 mT)	5.0 cm
Payment card	400 Gs (40.0 mT)	2.0 cm
HDD hard drive	600 Gs (60.0 mT)	1.5 cm

A strong magnetic field is a real danger to IT equipment as well as pacemakers. These magnets generate a flux that prevents correct functioning of sensitive medical devices. Remember: the invisible magnetic field acts through matter and plastic. Increased vigilance must be exercised by people with cochlear implants and insulin pumps. Also at risk are: mechanical watches, remotes, membranes, and displays. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

Table 8: Collisions (cracking risk) - collision effects
MW 38x3.5 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	16.10 km/h (4.47 m/s)	0.30 J
30 mm	23.11 km/h (6.42 m/s)	0.61 J
50 mm	29.52 km/h (8.20 m/s)	1.00 J
100 mm	41.70 km/h (11.58 m/s)	2.00 J

Neodymium magnets are very brittle – a strong collision with metal causes immediate chipping. Pay attention to connection velocity – a magnet released freely becomes dangerous. Striking energy can cause material chips or injury to fingers. Always hold the magnet during installation so it doesn't slam with momentum against the steel surface. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Wear safety glasses when playing 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. Buoyancy helps in lifting finds.

1. Shear force

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

2. Steel thickness impact

*Thin metal sheet (e.g. 0.5mm PC case) drastically weakens the holding force.

3. Temperature resistance

*For N38 material, the critical limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.14

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 incredibly powerful rod magnet, composed of advanced NdFeB material, which, at dimensions of Ø38x3.5 mm, guarantees optimal power. This specific item is characterized by a tolerance of ±0.1mm and industrial build quality, making it an ideal solution for professional engineers and designers. As a magnetic rod with significant force (approx. 5.09 kg), this product is in stock from our European logistics center, ensuring rapid order fulfillment. Additionally, its triple-layer Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

This model is ideal for building generators, advanced Hall effect sensors, and efficient filters, where field concentration on a small surface counts. Thanks to the pull force of 49.91 N with a weight of only 29.77 g, this cylindrical magnet is indispensable in miniature devices and wherever every gram matters.

Since our magnets have a tolerance of ±0.1mm, the best method is to glue them into holes with a slightly larger diameter (e.g., 38.1 mm) using two-component epoxy glues. To ensure long-term durability in automation, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing high repeatability 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 even stronger magnets in the same volume (Ø38x3.5), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.

This model is characterized by dimensions Ø38x3.5 mm, which, at a weight of 29.77 g, makes it an element with high magnetic energy density. The value of 49.91 N means that the magnet is capable of holding a weight many times exceeding its own mass of 29.77 g. The product has a [NiCuNi] coating, which protects the surface 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 38 mm. Such an arrangement is most desirable 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.

Strengths and weaknesses of neodymium magnets.

Advantages

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

They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (in laboratory conditions),
They maintain their magnetic properties even under close interference source,
Thanks to the elegant finish, the layer of nickel, gold-plated, or silver-plated gives an professional appearance,
The surface of neodymium magnets generates a concentrated magnetic field – this is a key feature,
Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
Possibility of custom shaping and modifying to complex applications,
Significant place in innovative solutions – they are commonly used in hard drives, drive modules, advanced medical instruments, and industrial machines.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which enables their usage in compact constructions

Limitations

Disadvantages of neodymium magnets:

They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
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.
Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
Due to limitations in realizing nuts and complex shapes in magnets, we propose using casing - magnetic mount.
Health risk resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, tiny parts of these magnets can complicate diagnosis medical after entering the body.
With large orders the cost of neodymium magnets is economically unviable,

Lifting parameters

Maximum lifting force for a neodymium magnet – what it depends on?

The lifting capacity listed is a measurement result executed under standard conditions:

on a base made of mild steel, perfectly concentrating the magnetic field
possessing a massiveness of minimum 10 mm to ensure full flux closure
with an ground contact surface
with total lack of distance (without coatings)
during detachment in a direction perpendicular to the mounting surface
at conditions approx. 20°C

Key elements affecting lifting force

During everyday use, the real power is determined by a number of factors, listed from most significant:

Space between surfaces – every millimeter of distance (caused e.g. by varnish or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
Base massiveness – insufficiently thick steel does not accept the full field, causing part of the flux to be escaped into the air.
Material type – ideal substrate is pure iron steel. Cast iron may have worse magnetic properties.
Smoothness – ideal contact is possible only on polished steel. Rough texture reduce the real contact area, reducing force.
Operating temperature – neodymium magnets have a negative temperature coefficient. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).

Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under parallel forces the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet and the plate reduces the lifting capacity.

Warnings

Conscious usage

Handle magnets consciously. Their huge power can surprise even professionals. Stay alert and respect their power.

Flammability

Mechanical processing of neodymium magnets poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.

Pinching danger

Big blocks can crush fingers instantly. Do not put your hand between two attracting surfaces.

Demagnetization risk

Standard neodymium magnets (grade N) lose power when the temperature surpasses 80°C. This process is irreversible.

Magnets are brittle

Neodymium magnets are sintered ceramics, which means they are fragile like glass. Collision of two magnets leads to them breaking into small pieces.

Adults only

Only for adults. Small elements can be swallowed, causing serious injuries. Store out of reach of children and animals.

Threat to electronics

Device Safety: Neodymium magnets can damage payment cards and delicate electronics (heart implants, hearing aids, mechanical watches).

Warning for allergy sufferers

Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction happens, immediately stop working with magnets and wear gloves.

Phone sensors

An intense magnetic field interferes with the functioning of magnetometers in smartphones and navigation systems. Keep magnets near a smartphone to prevent breaking the sensors.

Medical interference

For implant holders: Strong magnetic fields affect medical devices. Keep minimum 30 cm distance or request help to handle the magnets.
