Pulling power drops drastically with every mm of spacing. Note that even the smallest gap (e.g., dirt, paint, veneer) significantly diminishes the holding power. Neodymiums hold optimally during direct contact; distance weakens the force. Analyze how flashily the load capacity drop, when the product does not touch directly to the steel surface. When planning the arrangement, eliminate redundant distances.

Table 2: Shear force (vertical surface)

This section defines the estimated shear load required to cause the sliding of the magnet downwards against a upright steel plate (considering standard friction coefficient). This value varies with the separation distance between the magnet and the metal.

Table 3: Vertical assembly (shearing) - vertical pull
MW 2x4 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.03 kg / 0.06 pounds 27.0 g / 0.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.02 kg / 0.04 pounds 18.0 g / 0.2 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.01 kg / 0.02 pounds 9.0 g / 0.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.05 kg / 0.10 pounds 45.0 g / 0.4 N

When placing a element on a vertical wall (e.g., a fridge), it will maintain barely approx. 20%-30% of its nominal power. Gravity as well as a low friction coefficient influence the fact that holders slide down easier than they pop off the substrate. Designing a hanger? Remember that the shear force is noticeably lower than the maximum static pull force. On a painted metal, the element will give way down under a significantly smaller weight. Using a rubber pad can significantly increase the grip.

0.5 mm	10%	0.01 kg / 0.02 pounds 9.0 g / 0.1 N
1 mm	25%	0.02 kg / 0.05 pounds 22.5 g / 0.2 N
2 mm	50%	0.05 kg / 0.10 pounds 45.0 g / 0.4 N
3 mm	75%	0.07 kg / 0.15 pounds 67.5 g / 0.7 N

10 mm	100%	0.09 kg / 0.20 pounds 90.0 g / 0.9 N
11 mm	100%	0.09 kg / 0.20 pounds 90.0 g / 0.9 N
12 mm	100%	0.09 kg / 0.20 pounds 90.0 g / 0.9 N

A thin metal plate is not enough to focus the full magnetic flux, which wastes potential of the holder. Should you install a neodymium to a thin surface, the flux will pass right through and the holding will be smaller. To achieve 100% of this neodymium's power, you need a suitably thick piece of metal. The saturation effect means that on delicate walls (e.g., car bodies), the product holds weaker. We recommend selecting the steel thickness based on the following data.

Table 5: Working in heat (stability) - thermal limit
MW 2x4 / N38

Ambient temp. (°C)	Power loss	Remaining pull (kg/lbs/g/N)	Status
20 °C	0.0%	0.09 kg / 0.20 pounds 90.0 g / 0.9 N	OK
40 °C	-2.2%	0.09 kg / 0.19 pounds 88.0 g / 0.9 N	OK
60 °C	-4.4%	0.09 kg / 0.19 pounds 86.0 g / 0.8 N	OK
80 °C	-6.6%	0.08 kg / 0.19 pounds 84.1 g / 0.8 N
100 °C	-28.8%	0.06 kg / 0.14 pounds 64.1 g / 0.6 N

Ordinary NdFeB products change their properties parameters after exceeding the maximum temperature. Watch out for overheating – excessive heat can permanently damage this magnet. As the temperature rises, the neodymium's power briefly drops. Do not use this magnet close to heaters higher than its safe range. Ignoring the limit will result in permanent loss of magnetism.

*Engineering note: Thermal stability is determined by both grade, and the Permeance Coefficient Pc. Low-profile magnets (low permeance coefficient) are more susceptible to demagnetization under lower heat stress compared to rod magnets. The danger warning in the table indicates a risk of irreversible loss for this specific geometry.

Two magnetic products attract each other from a wider radius than a magnet and steel setup. The setup of magnet-to-magnet creates a more powerful interaction and a further horizon of operation. Planning to create a powerful holder? Use a pair of magnets instead of one magnet and a striker plate. Exercise caution that when connecting a pair of magnets, the collision energy is massive. The levitation is marginally weaker than the connection force, but still significant.
*Field value between like poles drops to ~0 Gs at the geometric center of the gap (resulting from vector opposition).
Attention: Calculations show sliding force of a pair of matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

Extremely neodym field is a serious hazard to IT equipment and medical implants. These magnets produce a field that destroys function of sensitive medical devices. Notice: the invisible magnetic field penetrates the body and glass. Special caution must be exercised by people with cochlear implants and insulin pumps. The risk also applies to: automatic timepieces, car keys, speakers, and displays. Do not bring the product near payment cards, HDD media, or sensitive navigation tools.

NdFeB products are delicate – a collision with steel can result in shattering. Pay attention to connection velocity – a neodymium left loose becomes dangerous. Impact energy can cause material chips or painful pinches to skin. Hold the magnet firmly during bringing near metal so it doesn't hit violently against the metal. A collision at high speed means shattering of the magnet. Wear eye protection when handling with powerful specimens.

Rust risk: 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. Buoyancy helps in lifting finds.

1. Vertical hold

*Note: On a vertical wall, the magnet retains just ~20% of its max power.

2. Plate thickness effect

*Thin steel (e.g. 0.5mm PC case) severely weakens the holding force.

3. Thermal stability

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 1.21

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 exceptionally strong rod magnet, made from modern NdFeB material, which, with dimensions of Ø2x4 mm, guarantees maximum efficiency. The MW 2x4 / N38 component features a tolerance of ±0.1mm and professional build quality, making it an ideal solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 0.09 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, guaranteeing an aesthetic appearance and durability for years.

This model is perfect for building electric motors, advanced sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the pull force of 0.86 N with a weight of only 0.09 g, this rod is indispensable in electronics and wherever every gram matters.

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., 2.1 mm) using two-component epoxy glues. 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 90% 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 (Ø2x4), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.

The presented product is a neodymium magnet with precisely defined parameters: diameter 2 mm and height 4 mm. The key parameter here is the lifting capacity amounting to approximately 0.09 kg (force ~0.86 N), which, with such defined dimensions, proves the high power 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 2 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.

Strengths and weaknesses of rare earth magnets.

Benefits

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

Their magnetic field is durable, and after approximately ten years it decreases only by ~1% (theoretically),
Neodymium magnets are extremely resistant to demagnetization caused by magnetic disturbances,
Thanks to the metallic finish, the plating of Ni-Cu-Ni, gold-plated, or silver gives an modern appearance,
Magnets possess exceptionally strong magnetic induction on the surface,
Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
Possibility of accurate machining and adapting to precise requirements,
Key role in modern technologies – they are commonly used in hard drives, motor assemblies, diagnostic systems, also technologically advanced constructions.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Weaknesses

What to avoid - cons of neodymium magnets: application proposals

Brittleness is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a steel housing, which not only protects them against impacts but also increases their durability
NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation as well as corrosion.
Due to limitations in producing threads and complex shapes in magnets, we propose using casing - magnetic holder.
Health risk resulting from small fragments of magnets pose a threat, in case of ingestion, which becomes key in the context of child safety. Additionally, small components of these products are able to complicate diagnosis medical after entering the body.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Holding force characteristics

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

The force parameter is a result of laboratory testing executed under specific, ideal conditions:

with the contact of a sheet made of special test steel, guaranteeing full magnetic saturation
whose thickness reaches at least 10 mm
with a surface perfectly flat
with zero gap (no coatings)
under perpendicular force direction (90-degree angle)
in stable room temperature

Key elements affecting lifting force

Effective lifting capacity is influenced by working environment parameters, mainly (from priority):

Distance – the presence of any layer (paint, dirt, gap) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
Direction of force – highest force is obtained only during pulling at a 90° angle. The shear force of the magnet along the surface is standardly several times smaller (approx. 1/5 of the lifting capacity).
Base massiveness – insufficiently thick steel does not close the flux, causing part of the flux to be wasted to the other side.
Material type – the best choice is pure iron steel. Hardened steels may attract less.
Plate texture – smooth surfaces ensure maximum contact, which improves field saturation. Uneven metal reduce efficiency.
Thermal conditions – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and in frost gain strength (up to a certain limit).

Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, however under parallel forces the load capacity is reduced by as much as 5 times. In addition, even a minimal clearance between the magnet and the plate lowers the load capacity.

Safety rules for work with NdFeB magnets

Fire warning

Drilling and cutting of NdFeB material carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.

Compass and GPS

Navigation devices and smartphones are highly susceptible to magnetism. Direct contact with a strong magnet can decalibrate the sensors in your phone.

Danger to the youngest

These products are not intended for children. Accidental ingestion of several magnets can lead to them attracting across intestines, which poses a direct threat to life and necessitates urgent medical intervention.

Caution required

Before use, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Be predictive.

Warning for heart patients

Medical warning: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have electronic implants.

Avoid contact if allergic

Nickel alert: The Ni-Cu-Ni coating contains nickel. If an allergic reaction appears, immediately stop working with magnets and wear gloves.

Thermal limits

Control the heat. Exposing the magnet above 80 degrees Celsius will ruin its magnetic structure and strength.

Electronic devices

Do not bring magnets near a purse, laptop, or TV. The magnetism can permanently damage these devices and erase data from cards.

Eye protection

Neodymium magnets are ceramic materials, which means they are fragile like glass. Collision of two magnets leads to them cracking into small pieces.

Bone fractures

Large magnets can crush fingers in a fraction of a second. Under no circumstances put your hand between two attracting surfaces.
