Grip strength weakens drastically per each millimeter of distance. Note that even a very thin break (e.g., dirt, paint, rust) significantly reduces the pull force. Magnetic products operate optimally during direct contact; air break weakens the power. Notice how quickly the load capacity fall, when the product does not touch tightly to the metal substrate. When planning the assembly, avoid unnecessary gaps.

This section calculates the theoretical weight limit necessary to initiate the downward movement of the magnet downwards against a upright steel plate (assuming typical friction). This parameter varies with the gap size between the magnet and the metal.

Table 3: Vertical assembly (shearing) - behavior on slippery surfaces
MW 100x30 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg)
Raw steel	µ = 0.3 30% Nominalnej Siły	64.55 kg / 64551.0 g 633.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	43.03 kg / 43034.0 g 422.2 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	21.52 kg / 21517.0 g 211.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	107.59 kg / 107585.0 g 1055.4 N

When mounting a element on a upright surface (e.g., a car body), it will only hold only about 1/5 of its nominal power. Gravity and a low friction coefficient influence the fact that holders move down faster than they detach. Planning a vertical fastening? Remember that the shear force is significantly lower than the perpendicular breakaway force. On a slippery surface, the element will slip down under a much lighter cargo. Utilizing a rubberized pad can significantly increase the grip.

Table 4: Material efficiency (substrate influence) - sheet metal selection
MW 100x30 / N38

Steel thickness (mm)	% power	Real pull force (kg)
0.5 mm	3%	7.17 kg / 7172.3 g 70.4 N
1 mm	8%	17.93 kg / 17930.8 g 175.9 N
2 mm	17%	35.86 kg / 35861.7 g 351.8 N
5 mm	42%	89.65 kg / 89654.2 g 879.5 N
10 mm	83%	179.31 kg / 179308.3 g 1759.0 N

A thin metal plate is incapable of conduct the entire magnetic field, which weakens actual performance of the magnet. Should you mount a strong magnet to a thin surface, the magnetism will penetrate right through and the pull force will drop sharply. To achieve full efficiency of this neodymium's power, you require a sufficiently solid piece of steel. The material oversaturation causes that on delicate walls (e.g., car bodies), the magnet works worse. We advise picking the steel cross-section from these parameters.

Classic neodymiums irreversibly lose strength above the temperature limit. Watch out for overheating – heat can permanently demagnetize this product. With increasing heat, the neodymium's power momentarily drops. Do not use this magnet close to ovens exceeding its operating temperature limit. Ignoring the limit will result in irreversible degradation of magnetism.

*Technical advisory: Thermal stability depends not only on the material grade, and the Permeance Coefficient Pc. Low-profile magnets (pancake types) risk losing magnetic properties under lower heat stress than long magnets. Warning indicator in the table points to a risk of irreversible loss for this specific geometry.

Two strong neodymiums interact from a wider radius than a magnet and steel combination. The setup of magnet-to-magnet creates a more powerful interaction and a wider radius of performance. Want to build a strong closure? Apply two magnets instead of a neodymium and a striker plate. Be careful that when attracting two neodymiums, the impact force is huge. The repulsion force is a bit weaker than the connection force, but still significant.
*Flux density between like poles reaches ~0 Gs in the exact middle between the magnets (resulting from vector opposition).

A strong magnetic field poses a serious hazard to electronics and pacemakers. These NdFeB products produce a field that disrupts operation of digital equipment. Notice: the unseen radiation penetrates the body and housings. Special caution must be exercised by people with cochlear implants and insulin pumps. Influence will be felt by: automatic timepieces, car keys, membranes, and displays. Avoid contact with magnetic cards, HDD media, or sensitive navigation tools.

Neodymium magnets are prone to chipping – a collision with steel risks their cracking. Watch the impact speed – a magnet released freely becomes dangerous. Impact energy can destroy the magnet or painful pinches to fingers. Hold the magnet firmly during mounting so it doesn't hit with great force against the steel surface. A collision at high speed ends with a crack of the magnet. Use safety goggles when playing with large magnets.

Warning: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.

In water, the magnet feels stronger thanks to Archimedes' principle. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Vertical hold

*Caution: On a vertical wall, the magnet retains merely a fraction of its max power.

2. Efficiency vs thickness

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

3. Temperature resistance

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.40

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 an incredibly powerful rod magnet, composed of advanced NdFeB material, which, with dimensions of Ø100x30 mm, guarantees the highest energy density. This specific item boasts high dimensional repeatability and industrial build quality, making it an ideal solution for the most demanding engineers and designers. As a magnetic rod with impressive force (approx. 215.17 kg), this product is in stock from our European logistics center, ensuring quick order fulfillment. Additionally, its triple-layer Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

It successfully proves itself in modeling, advanced robotics, and broadly understood industry, serving as a positioning or actuating element. Thanks to the pull force of 2110.78 N with a weight of only 1767.15 g, this rod is indispensable in electronics and wherever low weight is crucial.

Due to the brittleness of the NdFeB material, we absolutely advise against force-fitting (so-called press-fit), as this risks immediate cracking of this precision component. To ensure long-term durability in industry, specialized industrial adhesives are used, which do not react with the nickel coating 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 (Ø100x30), 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 Ø100x30 mm, which, at a weight of 1767.15 g, makes it an element with impressive magnetic energy density. The value of 2110.78 N means that the magnet is capable of holding a weight many times exceeding its own mass of 1767.15 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 30 mm), which means that the N and S poles are located on the flat, circular surfaces. 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 diametrically if your project requires it.

Pros and cons of Nd₂Fe₁₄B magnets.

Pros

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

They retain magnetic properties for almost ten years – the drop is just ~1% (based on simulations),
They maintain their magnetic properties even under external field action,
The use of an aesthetic coating of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
Magnets are characterized by very high magnetic induction on the active area,
Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
Considering the ability of free molding and customization to custom solutions, neodymium magnets can be modeled in a variety of geometric configurations, which increases their versatility,
Wide application in advanced technology sectors – they are utilized in hard drives, brushless drives, medical devices, also modern systems.
Thanks to their power density, small magnets offer high operating force, in miniature format,

Disadvantages

Disadvantages of neodymium magnets:

They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
They rust in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
Limited ability of making threads in the magnet and complicated shapes - recommended is a housing - mounting mechanism.
Potential hazard resulting from small fragments of magnets are risky, when accidentally swallowed, which is particularly important in the context of child safety. It is also worth noting that tiny parts of these products can complicate diagnosis medical in case of swallowing.
Due to complex production process, their price is relatively high,

Holding force characteristics

Optimal lifting capacity of a neodymium magnet – what it depends on?

Magnet power was determined for ideal contact conditions, taking into account:

using a base made of high-permeability steel, functioning as a ideal flux conductor
with a thickness no less than 10 mm
characterized by lack of roughness
under conditions of no distance (metal-to-metal)
during detachment in a direction perpendicular to the plane
at conditions approx. 20°C

Magnet lifting force in use – key factors

In practice, the actual holding force is determined by a number of factors, ranked from most significant:

Air gap (betwixt the magnet and the metal), because even a very small distance (e.g. 0.5 mm) results in a drastic drop in lifting capacity by up to 50% (this also applies to paint, rust or dirt).
Direction of force – maximum parameter is reached only during perpendicular pulling. The force required to slide of the magnet along the surface is standardly many times lower (approx. 1/5 of the lifting capacity).
Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
Chemical composition of the base – low-carbon steel gives the best results. Alloy admixtures decrease magnetic properties and lifting capacity.
Base smoothness – the smoother and more polished the plate, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
Thermal conditions – NdFeB sinters have a negative temperature coefficient. When it is hot they lose power, and in frost gain strength (up to a certain limit).

Lifting capacity was measured by applying a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, in contrast under shearing force the load capacity is reduced by as much as 75%. Additionally, even a minimal clearance between the magnet and the plate decreases the load capacity.

Precautions when working with NdFeB magnets

Heat warning

Standard neodymium magnets (N-type) lose magnetization when the temperature goes above 80°C. Damage is permanent.

Fire warning

Fire warning: Neodymium dust is highly flammable. Do not process magnets without safety gear as this risks ignition.

Adults only

NdFeB magnets are not toys. Swallowing multiple magnets can lead to them connecting inside the digestive tract, which poses a critical condition and requires urgent medical intervention.

Data carriers

Data protection: Strong magnets can ruin payment cards and delicate electronics (heart implants, hearing aids, timepieces).

Compass and GPS

A strong magnetic field negatively affects the functioning of magnetometers in smartphones and GPS navigation. Maintain magnets near a device to avoid breaking the sensors.

Nickel allergy

It is widely known that nickel (the usual finish) is a common allergen. If you have an allergy, prevent direct skin contact and choose encased magnets.

Eye protection

Beware of splinters. Magnets can fracture upon violent connection, launching shards into the air. Wear goggles.

Bone fractures

Large magnets can crush fingers in a fraction of a second. Never put your hand between two strong magnets.

Immense force

Before starting, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.

Life threat

Life threat: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have electronic implants.
