Magnetic force decreases sharply with every mm of spacing. Keep in mind that every additional insulation layer (e.g., contamination, paint, veneer) noticeably weakens the grip. Magnetic products hold optimally during direct contact; gap nullifies the power. See how rapidly the parameters drop, when the magnet does not touch tightly to the metal substrate. When designing the assembly, eliminate redundant distances.

This section indicates the approximate shear load necessary to initiate the shifting of the magnet vertically against a upright steel wall (considering typical friction coefficient). This value depends on the gap size between the magnet and the surface.

Table 3: Wall mounting (shearing) - vertical pull
MW 45x15 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	14.56 kg / 32.11 lbs 14565.0 g / 142.9 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	9.71 kg / 21.41 lbs 9710.0 g / 95.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	4.86 kg / 10.70 lbs 4855.0 g / 47.6 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	24.28 kg / 53.52 lbs 24275.0 g / 238.1 N

When placing a element on a vertical wall (e.g., a car body), it you can count on just about 1/5 of nominal attraction strength. Gravitational force as well as a weak degree of grip cause that holders slide down faster than they pop off the substrate. Planning a vertical fastening? Note that the shear force is noticeably lower than the maximum static pull force. On a painted metal, the holder will slip down under a significantly smaller cargo. Utilizing a rubberized pad can drastically increase the grip.

Steel thickness (mm)	% power	Real pull force (kg/lbs/g/N)
0.5 mm	5%	2.43 kg / 5.35 lbs 2427.5 g / 23.8 N

2 mm	25%	12.14 kg / 26.76 lbs 12137.5 g / 119.1 N
3 mm	38%	18.21 kg / 40.14 lbs 18206.2 g / 178.6 N
5 mm	63%	30.34 kg / 66.90 lbs 30343.8 g / 297.7 N
10 mm	100%	48.55 kg / 107.03 lbs 48550.0 g / 476.3 N
11 mm	100%	48.55 kg / 107.03 lbs 48550.0 g / 476.3 N
12 mm	100%	48.55 kg / 107.03 lbs 48550.0 g / 476.3 N

A thin sheet is not enough to focus the entire magnetic field, which squanders power of the magnet. If you install a neodymium to a thin surface, the flux will penetrate right through and the holding will be smaller. To squeeze the maximum of this magnet's power, you need a suitably thick backing of metal. The saturation phenomenon means that on delicate walls (e.g., car bodies), the product works worse. We suggest choosing the steel cross-section based on the following data.

Standard neodymium magnets irreversibly lose strength past the thermal threshold. Avoid high temperatures – heat can irreversibly demagnetize this magnet. With every degree above norm, the neodymium's force momentarily decreases. Refrain from using this product close to heaters higher than its safe range. Too high temperature will lead to irreversible degradation of magnetism.

*Engineering note: Temperature resistance is determined by both grade, as well as the dimension ratios. Low-profile magnets (low Pc) risk losing magnetic properties under lower heat stress compared to rod magnets. Red status in the table points to permanent field degradation for this particular item.

Two magnetic products interact from a significantly greater distance than a magnet and steel setup. The connection of two magnets generates a stronger field and a further horizon of operation. Designing a powerful holder? Use a pair of magnets instead of a neodymium and a steel. Exercise caution that when bringing together two magnets, the pinch force is extreme. The levitation is marginally weaker than the attraction, but still significant.
*Field value in repulsion mode reaches ~0 Gs at the midpoint of the gap (caused by magnetic field nullification).
Attention: Calculations apply to sliding force of two same magnets (friction ~0.15 for Ni-Ni coating).

Table 7: Protective zones (electronics) - warnings
MW 45x15 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	20.5 cm

Extremely neodym field poses a real danger to electronics as well as pacemakers. These magnets generate a flux that prevents correct functioning of digital equipment. Remember: the invisible magnetic field acts through matter and glass. Increased vigilance must be exercised by people with cochlear implants and insulin pumps. Also at risk are: automatic timepieces, car keys, membranes, and screens. Do not place the magnet near cards, hard drives, or precise measuring instruments.

Table 8: Impact energy (cracking risk) - warning
MW 45x15 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	20.09 km/h (5.58 m/s)	2.79 J
30 mm	29.29 km/h (8.14 m/s)	5.92 J
50 mm	37.23 km/h (10.34 m/s)	9.57 J
100 mm	52.54 km/h (14.59 m/s)	19.05 J

Magnetic elements are very brittle – a violent impact against metal causes immediate chipping. Watch the impact speed – a magnet released freely turns into a projectile. Impact energy can cause material chips or injury to skin. Always hold the magnet during installation so it doesn't hit with great force against the steel surface. A collision at high speed ends with a crack of the neodymium. Wear eye protection when handling 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.

The magnetic field penetrates through water without any losses. However, remember the water resistance when pulling the rope quickly.

1. Sliding resistance

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

2. Plate thickness effect

*Thin steel (e.g. computer case) significantly limits the holding force.

3. Thermal stability

*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) = 0.44

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.

The presented product is an incredibly powerful cylinder magnet, composed of advanced NdFeB material, which, at dimensions of Ø45x15 mm, guarantees maximum efficiency. The MW 45x15 / N38 component features 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. 48.55 kg), this product is in stock from our warehouse in Poland, ensuring quick order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating secures it against corrosion in typical 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 high power of 476.32 N with a weight of only 178.92 g, this rod is indispensable in miniature devices and wherever low weight is crucial.

Since our magnets have a tolerance of ±0.1mm, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 45.1 mm) using epoxy glues. 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 strong enough for 90% of applications in modeling and machine building, where excessive miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø45x15), 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 Ø45x15 mm, which, at a weight of 178.92 g, makes it an element with impressive magnetic energy density. The value of 476.32 N means that the magnet is capable of holding a weight many times exceeding its own mass of 178.92 g. The product has a [NiCuNi] coating, which protects the surface against external factors, giving it an aesthetic, silvery shine.

This cylinder is magnetized axially (along the height of 15 mm), which means that the N and S poles are located on the flat, circular surfaces. 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.

Strengths and weaknesses of Nd₂Fe₁₄B magnets.

Strengths

Besides their remarkable magnetic power, neodymium magnets offer the following advantages:

Their magnetic field remains stable, and after approximately ten years it drops only by ~1% (theoretically),
Magnets perfectly defend themselves against loss of magnetization caused by ambient magnetic noise,
By covering with a lustrous coating of nickel, the element presents an proper look,
Magnets exhibit excellent magnetic induction on the outer side,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
Considering the option of free shaping and customization to individualized solutions, NdFeB magnets can be modeled in a variety of geometric configurations, which amplifies use scope,
Wide application in modern technologies – they serve a role in hard drives, motor assemblies, medical devices, and multitasking production systems.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which enables their usage in miniature devices

Disadvantages

Characteristics of disadvantages of neodymium magnets: application proposals

At 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.
We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
Magnets exposed to a humid environment can rust. Therefore during using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
Limited possibility of creating nuts in the magnet and complicated forms - preferred is a housing - mounting mechanism.
Possible danger resulting from small fragments of magnets pose a threat, if swallowed, which gains importance in the context of child safety. It is also worth noting that small elements of these products can complicate diagnosis medical when they are in the body.
With large orders the cost of neodymium magnets is a challenge,

Holding force characteristics

Best holding force of the magnet in ideal parameters – what it depends on?

Information about lifting capacity was determined for optimal configuration, assuming:

with the contact of a yoke made of special test steel, guaranteeing maximum field concentration
possessing a thickness of minimum 10 mm to avoid saturation
with an polished contact surface
without the slightest insulating layer between the magnet and steel
during pulling in a direction vertical to the plane
at conditions approx. 20°C

Lifting capacity in real conditions – factors

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

Gap between surfaces – even a fraction of a millimeter of distance (caused e.g. by veneer 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.
Substrate thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
Plate material – low-carbon steel attracts best. Alloy admixtures reduce magnetic properties and holding force.
Surface finish – full contact is obtained only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
Heat – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity was assessed with the use of a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, however under attempts to slide the magnet the load capacity is reduced by as much as 75%. Moreover, even a slight gap between the magnet and the plate lowers the lifting capacity.

Safe handling of NdFeB magnets

Dust is flammable

Fire hazard: Neodymium dust is explosive. Do not process magnets without safety gear as this may cause fire.

Allergic reactions

Certain individuals suffer from a contact allergy to nickel, which is the standard coating for neodymium magnets. Extended handling may cause an allergic reaction. We strongly advise wear protective gloves.

Fragile material

Despite the nickel coating, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.

Health Danger

For implant holders: Powerful magnets affect electronics. Keep at least 30 cm distance or ask another person to handle the magnets.

Precision electronics

A powerful magnetic field negatively affects the operation of magnetometers in smartphones and GPS navigation. Keep magnets close to a device to prevent damaging the sensors.

Keep away from children

Neodymium magnets are not toys. Eating several magnets may result in them attracting across intestines, which poses a critical condition and necessitates urgent medical intervention.

Bodily injuries

Mind your fingers. Two powerful magnets will join instantly with a force of several hundred kilograms, destroying anything in their path. Be careful!

Power loss in heat

Do not overheat. NdFeB magnets are susceptible to heat. If you require operation above 80°C, look for HT versions (H, SH, UH).

Data carriers

Avoid bringing magnets close to a purse, laptop, or TV. The magnetism can irreversibly ruin these devices and erase data from cards.

Caution required

Handle magnets with awareness. Their huge power can surprise even professionals. Be vigilant and respect their force.
