Pulling power decreases significantly per each millimeter of spacing. Note that every additional insulation layer (e.g., contamination, varnish, veneer) significantly weakens the grip. Neodymiums hold optimally at the point of direct contact; air break nullifies the power. Observe how quickly the pull force plummet, when the magnet does not adhere directly to the metal substrate. When calculating the assembly, discard additional spacers.

This section presents the approximate force required to start the slippage of the magnet vertically along a vertical steel plate (considering typical friction coefficient). The holding force depends on the gap size between the magnet and the surface.

Table 3: Wall mounting (sliding) - 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 hanging a magnet on a upright wall (e.g., a board), it you can count on barely approx. 1/5 of nominal attraction strength. Gravitational force and a low friction coefficient cause that holders slide down easier than they detach. Designing a vertical fastening? Note that the shear force is significantly lower than the maximum static pull force. On a painted metal, the element will give way down under a much lighter load. Application of an anti-slip layer can significantly increase the grip.

Table 4: Material efficiency (saturation) - sheet metal selection
MW 2x4 / N38

Steel thickness (mm)	% power	Real pull force (kg/lbs/g/N)
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
5 mm	100%	0.09 kg / 0.20 pounds 90.0 g / 0.9 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 sheet is unable to absorb the full magnetic flux, which wastes potential of the holder. Should you install a neodymium to a thin surface, the flux will penetrate right through and the holding will be smaller. To squeeze full efficiency of this magnet's power, you require a sufficiently solid backing of steel. The saturation effect means that on delicate walls (e.g., car bodies), the magnet works worse. We suggest choosing the steel dimension based on the following data.

Table 5: Thermal resistance (material behavior) - thermal limit

100 °C	-28.8%	0.06 kg / 0.14 pounds 64.1 g / 0.6 N

Ordinary NdFeB products change their properties power after exceeding the maximum temperature. Avoid high temperatures – high temperature can permanently demagnetize this magnet. As the temperature rises, the neodymium's power temporarily decreases. Do not use this product close to ovens higher than its working range. Exceeding the critical threshold will lead to irreversible degradation of magnetism.

*Engineering note: Temperature resistance depends not only on the material grade, as well as the dimension ratios. Flat magnets (low permeance coefficient) risk losing magnetic properties under lower heat stress compared to rod magnets. The danger warning in the table signals a risk of irreversible loss for this specific geometry.

Two magnetic products attract each other from a much further distance than a magnet and sheet setup. The connection of two magnets generates a stronger field and a wider radius of performance. Designing a strong closure? Use a pair of magnets instead of a neodymium and a striker plate. Be careful that when connecting a pair of magnets, the collision energy is huge. The levitation is slightly lower than the connection force, but still impressive.
*The magnetic induction in repulsion mode drops to ~0 Gs in the exact middle between the magnets (due to field cancellation).
Attention: Figures show friction force of two same magnets (friction ~0.15 for Ni-Ni layer).

Powerful magnet radiation poses a serious hazard to electronics as well as medical implants. These neodymiums produce a field that destroys function of digital equipment. Notice: the unseen radiation penetrates the body and glass. Special caution must be exercised by people with hearing aids and insulin pumps. The risk also applies to: mechanical watches, remotes, membranes, and displays. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Table 8: Impact energy (kinetic energy) - collision effects
MW 2x4 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	31.89 km/h (8.86 m/s)	0.00 J
30 mm	55.24 km/h (15.34 m/s)	0.01 J
50 mm	71.31 km/h (19.81 m/s)	0.02 J
100 mm	100.85 km/h (28.01 m/s)	0.04 J

Neodymium magnets are prone to chipping – a strong collision with metal can result in shattering. Control the attraction moment – a magnet released freely speeds with massive force. Impact energy can destroy the magnet or dangerous crushing to skin. Always hold the magnet during mounting so it doesn't hit with great force against the steel surface. A collision at high speed means shattering of the neodymium. Wear eye protection when handling with large magnets.

Rust risk: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

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

*Warning: On a vertical wall, the magnet holds just approx. 20-30% of its nominal pull.

2. Steel thickness impact

*Thin steel (e.g. 0.5mm PC case) drastically reduces the holding force.

3. Temperature resistance

*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) = 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.

This product is an extremely powerful cylindrical magnet, composed of modern NdFeB material, which, at dimensions of Ø2x4 mm, guarantees optimal power. The MW 2x4 / N38 model features an accuracy of ±0.1mm and professional build quality, making it an excellent solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 0.09 kg), this product is available off-the-shelf from our European logistics center, ensuring quick order fulfillment. Additionally, 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 fastening or actuating element. Thanks to the high power of 0.86 N with a weight of only 0.09 g, this rod is indispensable in electronics and wherever every gram matters.

Due to the delicate structure of the ceramic sinter, you must not use force-fitting (so-called press-fit), as this risks immediate cracking of this professional component. To ensure long-term durability in industry, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.

Magnets N38 are strong enough 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.

This model is characterized by dimensions Ø2x4 mm, which, at a weight of 0.09 g, makes it an element with impressive magnetic energy density. The value of 0.86 N means that the magnet is capable of holding a weight many times exceeding its own mass of 0.09 g. The product has a [NiCuNi] coating, which protects the surface against oxidation, giving it an aesthetic, silvery shine.

This rod magnet is magnetized axially (along the height of 4 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 diametrically if your project requires it.

Strengths as well as weaknesses of Nd₂Fe₁₄B magnets.

Advantages

In addition to their long-term stability, neodymium magnets provide the following advantages:

They retain magnetic properties for almost 10 years – the drop is just ~1% (in theory),
Neodymium magnets prove to be remarkably resistant to loss of magnetic properties caused by external magnetic fields,
Thanks to the metallic finish, the layer of nickel, gold, or silver-plated gives an elegant appearance,
The surface of neodymium magnets generates a maximum magnetic field – this is one of their assets,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
Thanks to versatility in forming and the ability to adapt to individual projects,
Huge importance in innovative solutions – they serve a role in magnetic memories, electric motors, medical devices, and industrial machines.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which allows their use in compact constructions

Disadvantages

Problematic aspects of neodymium magnets and proposals for their use:

At strong impacts they can crack, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
Due to limitations in realizing nuts and complicated forms in magnets, we propose using a housing - magnetic mechanism.
Potential hazard resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which is particularly important in the context of child safety. Additionally, small elements of these devices are able to be problematic in diagnostics medical after entering the body.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities

Lifting parameters

Maximum magnetic pulling force – what affects it?

Breakaway force was determined for the most favorable conditions, including:

with the application of a yoke made of low-carbon steel, guaranteeing maximum field concentration
whose transverse dimension reaches at least 10 mm
characterized by lack of roughness
without the slightest insulating layer between the magnet and steel
under perpendicular force direction (90-degree angle)
at room temperature

Determinants of practical lifting force of a magnet

It is worth knowing that the application force will differ depending on elements below, in order of importance:

Gap between surfaces – every millimeter of distance (caused e.g. by veneer or dirt) diminishes the pulling force, often by half at just 0.5 mm.
Angle of force application – highest force is obtained only during perpendicular pulling. The resistance to sliding of the magnet along the surface is standardly many times smaller (approx. 1/5 of the lifting capacity).
Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
Metal type – different alloys attracts identically. High carbon content worsen the interaction with the magnet.
Smoothness – full contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
Thermal factor – high temperature reduces pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.

Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under shearing force the load capacity is reduced by as much as 5 times. Moreover, even a slight gap between the magnet and the plate reduces the lifting capacity.

H&S for magnets

Bodily injuries

Large magnets can smash fingers in a fraction of a second. Under no circumstances place your hand betwixt two attracting surfaces.

Power loss in heat

Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will destroy its magnetic structure and pulling force.

GPS and phone interference

Note: rare earth magnets produce a field that confuses sensitive sensors. Keep a separation from your mobile, tablet, and GPS.

Combustion hazard

Powder generated during machining of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.

Electronic hazard

Intense magnetic fields can erase data on payment cards, hard drives, and other magnetic media. Stay away of at least 10 cm.

Skin irritation risks

Some people suffer from a contact allergy to nickel, which is the common plating for neodymium magnets. Frequent touching might lead to a rash. We strongly advise wear safety gloves.

Handling guide

Be careful. Neodymium magnets act from a distance and snap with huge force, often quicker than you can react.

Do not give to children

Always keep magnets away from children. Choking hazard is high, and the effects of magnets clamping inside the body are life-threatening.

Fragile material

Watch out for shards. Magnets can fracture upon uncontrolled impact, launching shards into the air. Wear goggles.

Warning for heart patients

People with a ICD should maintain an absolute distance from magnets. The magnetic field can disrupt the operation of the implant.
