Magnetic force decreases significantly with every mm of gap. Keep in mind that even the smallest gap (e.g., contamination, varnish, rust) strongly diminishes the holding power. Magnets hold strongest during direct contact; distance weakens the power. Analyze how quickly the parameters drop, when the magnet does not touch flatly to the metal substrate. When calculating the assembly, avoid unnecessary gaps.

Table 2: Slippage force (vertical surface)
MW 45x35 / N38

The following data indicates the theoretical weight limit needed to cause the slippage of the magnet down along a upright steel plate (considering typical friction coefficient). This parameter depends on the separation distance between the magnet and the metal.

Table 3: Vertical assembly (shearing) - behavior on slippery surfaces
MW 45x35 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	20.69 kg / 45.62 pounds 20694.0 g / 203.0 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	13.80 kg / 30.41 pounds 13796.0 g / 135.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	6.90 kg / 15.21 pounds 6898.0 g / 67.7 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	34.49 kg / 76.04 pounds 34490.0 g / 338.3 N

When mounting a element on a vertical wall (e.g., a fridge), it will only hold barely about 1/5 of its maximum pull force. Gravity as well as a low friction coefficient mean that products move down easier than they pop off the substrate. Want to create a vertical fastening? Note that the sliding force is significantly lower than the perpendicular breakaway force. On a slippery surface, the holder will slide down under a much lighter load. Utilizing a rubberized pad can drastically increase the grip.

Table 4: Steel thickness (saturation) - sheet metal selection
MW 45x35 / N38

Steel thickness (mm)	% power	Real pull force (kg/lbs/g/N)
0.5 mm	3%	2.30 kg / 5.07 pounds 2299.3 g / 22.6 N
1 mm	8%	5.75 kg / 12.67 pounds 5748.3 g / 56.4 N
2 mm	17%	11.50 kg / 25.35 pounds 11496.7 g / 112.8 N
3 mm	25%	17.25 kg / 38.02 pounds 17245.0 g / 169.2 N
5 mm	42%	28.74 kg / 63.36 pounds 28741.7 g / 282.0 N
10 mm	83%	57.48 kg / 126.73 pounds 57483.3 g / 563.9 N
11 mm	92%	63.23 kg / 139.40 pounds 63231.7 g / 620.3 N
12 mm	100%	68.98 kg / 152.07 pounds 68980.0 g / 676.7 N

A too thin steel is not enough to take in the full magnetic flux, which wastes potential of the holder. If you install a neodymium to a weak sheet, the flux will pass right through and the holding will be smaller. To achieve the maximum of this magnet's potential, you require a sufficiently solid element of metal. The saturation phenomenon causes that on thin elements (e.g., car bodies), the holder shows lower pull force. We recommend selecting the steel dimension based on the following data.

Ordinary NdFeB products irreversibly lose parameters above the temperature limit. Avoid high temperatures – heat can irreversibly destroy this product. With increasing heat, the magnet's capacity momentarily drops. Avoid using this magnet in hot environments exceeding its operating temperature limit. Ignoring the limit will lead to irreversible degradation of magnetism.

*Technical advisory: Heat tolerance depends not only on the material grade, and the Permeance Coefficient Pc. Flat magnets (low Pc) may lose charge permanently under lower heat stress compared to rod magnets. The danger warning in the table signals a risk of irreversible loss for this particular item.

Two strong neodymiums attract each other from a significantly greater distance than a magnet and sheet combination. Such a system of magnet-to-magnet produces a massive flux and a further horizon of action. Planning to create a solid fastener? Apply two magnets instead of one magnet and a striker plate. Be careful that when connecting a pair of magnets, the impact force is massive. The levitation is a bit weaker than the connection force, but still impressive.
*Flux density for N-N configuration drops to ~0 Gs in the exact middle between the magnets (resulting from vector opposition).
Important: Figures refer to shear force of dual same magnets (friction ~0.15 for Ni-Ni plating).

Table 7: Safety (HSE) (implants) - warnings

Extremely neodym field is a large risk to electronics as well as pacemakers. These neodymiums produce a field that prevents correct functioning of digital equipment. Be aware: the invisible magnetic field penetrates the body and glass. Exceptional care must be taken by people with hearing aids and drug dispensers. Also at risk are: automatic timepieces, remotes, speakers, and displays. Do not bring the product near payment cards, HDD media, or precise measuring instruments.

Table 8: Impact energy (kinetic energy) - warning
MW 45x35 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	15.46 km/h (4.29 m/s)	3.85 J
30 mm	22.87 km/h (6.35 m/s)	8.42 J
50 mm	29.06 km/h (8.07 m/s)	13.61 J
100 mm	41.00 km/h (11.39 m/s)	27.07 J

NdFeB products are very brittle – a collision with steel risks their cracking. Pay attention to connection velocity – a neodymium left loose speeds with massive force. Impact energy can trigger coating fragments or dangerous crushing to fingers. Hold the magnet firmly during bringing near metal so it doesn't hit violently against the steel surface. A collision at high speed ends with a crack of the neodymium. Use safety goggles when playing 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!

Contrary to myths, water does not block the magnetic field. However, remember the water resistance when pulling the rope quickly.

1. Sliding resistance

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

2. Steel saturation

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

3. Power loss vs temp

*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) = 0.78

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 offered product is a very strong rod magnet, made from modern NdFeB material, which, at dimensions of Ø45x35 mm, guarantees the highest energy density. The MW 45x35 / N38 model boasts a tolerance of ±0.1mm and industrial build quality, making it an excellent solution for professional engineers and designers. As a cylindrical magnet with significant force (approx. 68.98 kg), this product is available off-the-shelf from our European logistics center, ensuring lightning-fast order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating effectively protects it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is ideal for building electric motors, advanced sensors, and efficient filters, where field concentration on a small surface counts. Thanks to the pull force of 676.73 N with a weight of only 417.49 g, this rod is indispensable in miniature devices and wherever low weight is crucial.

Since our magnets have a very precise dimensions, the best method is to glue them into holes with a slightly larger diameter (e.g., 45.1 mm) using two-component epoxy glues. To ensure stability in industry, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.

Magnets NdFeB grade N38 are suitable for the majority of applications in automation and machine building, where excessive miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø45x35), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.

The presented product is a neodymium magnet with precisely defined parameters: diameter 45 mm and height 35 mm. The value of 676.73 N means that the magnet is capable of holding a weight many times exceeding its own mass of 417.49 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 45 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 diametrically if your project requires it.

Pros as well as cons of Nd₂Fe₁₄B magnets.

Strengths

Apart from their superior magnetism, neodymium magnets have these key benefits:

They do not lose magnetism, even during approximately ten years – the decrease in power is only ~1% (according to tests),
They do not lose their magnetic properties even under external field action,
In other words, due to the aesthetic finish of nickel, the element gains a professional look,
Neodymium magnets ensure maximum magnetic induction on a contact point, which increases force concentration,
Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
Possibility of custom creating as well as adjusting to precise conditions,
Huge importance in modern industrial fields – they are commonly used in hard drives, drive modules, diagnostic systems, also industrial machines.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Limitations

Disadvantages of NdFeB magnets:

They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only protects the magnet but also improves its resistance to damage
When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
Due to limitations in producing threads and complex shapes in magnets, we recommend using cover - magnetic mechanism.
Possible danger resulting from small fragments of magnets pose a threat, if swallowed, which becomes key in the context of child safety. Furthermore, small components of these magnets are able to complicate diagnosis medical after entering the body.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Pull force analysis

Magnetic strength at its maximum – what contributes to it?

The declared magnet strength refers to the peak performance, measured under optimal environment, namely:

using a plate made of high-permeability steel, serving as a magnetic yoke
possessing a massiveness of min. 10 mm to avoid saturation
characterized by even structure
without any clearance between the magnet and steel
under axial force direction (90-degree angle)
in temp. approx. 20°C

Determinants of practical lifting force of a magnet

In practice, the actual holding force results from a number of factors, listed from most significant:

Distance (betwixt the magnet and the plate), as even a tiny clearance (e.g. 0.5 mm) leads to a drastic drop in force by up to 50% (this also applies to varnish, rust or dirt).
Load vector – maximum parameter is available only during perpendicular pulling. The force required to slide of the magnet along the surface is usually several times smaller (approx. 1/5 of the lifting capacity).
Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
Chemical composition of the base – low-carbon steel gives the best results. Alloy admixtures reduce magnetic properties and holding force.
Surface condition – smooth surfaces ensure maximum contact, which increases force. Uneven metal reduce efficiency.
Temperature – temperature increase results in weakening of force. It is worth remembering the thermal limit for a given model.

Lifting capacity testing was performed on a smooth plate of optimal thickness, under perpendicular forces, in contrast under parallel forces the load capacity is reduced by as much as 5 times. Additionally, even a slight gap between the magnet and the plate reduces the holding force.

Safety rules for work with NdFeB magnets

Operating temperature

Do not overheat. NdFeB magnets are sensitive to heat. If you require operation above 80°C, inquire about special high-temperature series (H, SH, UH).

Physical harm

Protect your hands. Two powerful magnets will join instantly with a force of massive weight, crushing everything in their path. Exercise extreme caution!

Keep away from computers

Device Safety: Neodymium magnets can ruin data carriers and sensitive devices (pacemakers, medical aids, timepieces).

Life threat

Patients with a pacemaker must maintain an large gap from magnets. The magnetic field can interfere with the functioning of the life-saving device.

Warning for allergy sufferers

Studies show that nickel (standard magnet coating) is a common allergen. If your skin reacts to metals, prevent touching magnets with bare hands and opt for encased magnets.

No play value

Strictly store magnets out of reach of children. Choking hazard is significant, and the effects of magnets connecting inside the body are tragic.

Handling guide

Handle with care. Rare earth magnets act from a distance and connect with huge force, often faster than you can move away.

Shattering risk

Protect your eyes. Magnets can fracture upon uncontrolled impact, ejecting shards into the air. Wear goggles.

Fire risk

Powder produced during machining of magnets is combustible. Avoid drilling into magnets unless you are an expert.

GPS Danger

Navigation devices and smartphones are highly susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can decalibrate the internal compass in your phone.
