Grip strength weakens sharply with every subsequent millimeter of distance. Note that even a very thin break (e.g., dirt, paint, dust) noticeably weakens the grip. Magnetic products hold most effectively during direct contact; distance nullifies the power. Analyze how rapidly the parameters drop, when the product does not touch tightly to the steel surface. When planning the mounting, avoid additional spacers.

Table 2: Sliding load (wall)

50 mm	Stal (~0.2)	0.00 kg / 0.00 pounds 0.0 g / 0.0 N

This section presents the approximate weight limit necessary to initiate the sliding of the magnet down against a vertical steel plate (assuming standard friction coefficient). This parameter depends on the distance between the magnet and the metal.

Table 3: Wall mounting (shearing) - vertical pull
MW 20x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	2.08 kg / 4.58 pounds 2079.0 g / 20.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.39 kg / 3.06 pounds 1386.0 g / 13.6 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.69 kg / 1.53 pounds 693.0 g / 6.8 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	3.47 kg / 7.64 pounds 3465.0 g / 34.0 N

When hanging a magnet on a vertical wall (e.g., a car body), it will only hold just approx. 20%-30% of its nominal power. Gravity as well as a low friction coefficient cause that products slip faster than they pull off. Planning a wall mount? Remember that the shear force is significantly lower than the maximum static pull force. On a smooth steel, the holder will slide down under a much lighter load. Utilizing a rubberized coating can drastically increase the grip.

Table 4: Material efficiency (saturation) - power losses
MW 20x5 / N38

Steel thickness (mm)	% power	Real pull force (kg/lbs/g/N)
0.5 mm	10%	0.69 kg / 1.53 pounds 693.0 g / 6.8 N
1 mm	25%	1.73 kg / 3.82 pounds 1732.5 g / 17.0 N
2 mm	50%	3.47 kg / 7.64 pounds 3465.0 g / 34.0 N
3 mm	75%	5.20 kg / 11.46 pounds 5197.5 g / 51.0 N
5 mm	100%	6.93 kg / 15.28 pounds 6930.0 g / 68.0 N
10 mm	100%	6.93 kg / 15.28 pounds 6930.0 g / 68.0 N
11 mm	100%	6.93 kg / 15.28 pounds 6930.0 g / 68.0 N
12 mm	100%	6.93 kg / 15.28 pounds 6930.0 g / 68.0 N

A thin metal plate is unable to absorb the entire magnetic field, which weakens actual performance of the holder. Should you mount a strong magnet to a thin surface, the field will penetrate right through and the pull force will drop sharply. To utilize full efficiency of this magnet's power, you require a sufficiently solid element of metal. The material oversaturation causes that on delicate walls (e.g., appliance housings), the holder holds weaker. We recommend selecting the steel cross-section based on the following data.

Table 5: Thermal resistance (material behavior) - power drop
MW 20x5 / N38

Ambient temp. (°C)	Power loss	Remaining pull (kg/lbs/g/N)	Status

40 °C	-2.2%	6.78 kg / 14.94 pounds 6777.5 g / 66.5 N	OK
60 °C	-4.4%	6.63 kg / 14.61 pounds 6625.1 g / 65.0 N
80 °C	-6.6%	6.47 kg / 14.27 pounds 6472.6 g / 63.5 N
100 °C	-28.8%	4.93 kg / 10.88 pounds 4934.2 g / 48.4 N

Standard neodymium magnets change their properties power after exceeding the maximum temperature. Avoid high temperatures – high temperature can irreversibly damage this magnet. With every degree above norm, the magnet's force briefly decreases. Refrain from using this magnet near heat sources higher than its safe range. Exceeding the critical threshold will result in destruction of magnetic properties.

*Engineering note: Thermal stability depends not only on the material grade, but also on the magnet's shape. Flat magnets (low Pc) are more susceptible to demagnetization at lower temperatures compared to rod magnets. Warning indicator in the table points to a risk of irreversible loss for this particular item.

Two strong neodymiums interact from a significantly greater distance than a neodymium and metal combination. The setup of magnet-to-magnet generates a stronger field and a larger range of performance. Planning to create a solid fastener? Utilize two neodymiums instead of one magnet and a striker plate. Remember that when attracting two neodymiums, the pinch force is massive. The levitation is slightly lower than the connection force, but still significant.
*Field value in repulsion mode is approximately ~0 Gs at the geometric center of the gap (resulting from vector opposition).
* Estimates refer to sliding force of two matching magnets (friction coefficient ~0.15 for Ni-Ni layer).

Extremely neodym field is a serious hazard to electronics and medical implants. These NdFeB products generate a flux that disrupts operation of digital equipment. Be aware: the invisible magnetic field acts through matter and plastic. Increased vigilance must be exercised by people with cochlear implants and drug dispensers. The risk also applies to: mechanical watches, car keys, membranes, and screens. Do not bring the product near payment cards, hard drives, or sensitive navigation tools.

Table 8: Collisions (cracking risk) - collision effects
MW 20x5 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	25.63 km/h (7.12 m/s)	0.30 J
30 mm	42.39 km/h (11.77 m/s)	0.82 J
50 mm	54.70 km/h (15.19 m/s)	1.36 J
100 mm	77.35 km/h (21.49 m/s)	2.72 J

Magnetic elements are prone to chipping – a strong collision with metal causes immediate chipping. Watch the impact speed – a magnet released freely becomes dangerous. Impact energy can trigger coating fragments or painful pinches to fingers. Always hold the magnet during installation so it doesn't slam with momentum against the steel surface. A contact at a velocity of dozens of km/h means shattering of the neodymium. Wear safety glasses when playing 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.

Water displaces steel, making heavy objects slightly lighter. However, remember the water resistance when pulling the rope quickly.

1. Vertical hold

*Note: On a vertical surface, the magnet retains just approx. 20-30% of its max power.

2. Efficiency vs thickness

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

3. Thermal stability

*For N38 material, 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) = 0.35

The chart above illustrates the magnetic characteristics of the material within the second quadrant of the hysteresis loop. 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 exceptionally strong cylinder magnet, composed of advanced NdFeB material, which, at dimensions of Ø20x5 mm, guarantees the highest energy density. The MW 20x5 / N38 component features high dimensional repeatability and industrial build quality, making it an excellent solution for the most demanding engineers and designers. As a cylindrical magnet with impressive force (approx. 6.93 kg), this product is in stock from our warehouse in Poland, ensuring quick order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

It successfully proves itself in modeling, advanced robotics, and broadly understood industry, serving as a fastening or actuating element. Thanks to the high power of 67.95 N with a weight of only 11.78 g, this cylindrical magnet 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., 20.1 mm) using two-component epoxy glues. To ensure stability in industry, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.

Grade N38 is the most popular standard for industrial neodymium magnets, offering a great economic balance and operational stability. If you need the strongest magnets in the same volume (Ø20x5), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.

This model is characterized by dimensions Ø20x5 mm, which, at a weight of 11.78 g, makes it an element with high magnetic energy density. The value of 67.95 N means that the magnet is capable of holding a weight many times exceeding its own mass of 11.78 g. The product has a [NiCuNi] coating, which secures it against external factors, giving it an aesthetic, silvery shine.

This rod magnet is magnetized axially (along the height of 5 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.

Advantages and disadvantages of rare earth magnets.

Pros

Besides their tremendous field intensity, neodymium magnets offer the following advantages:

Their magnetic field is durable, and after around ten years it drops only by ~1% (according to research),
Magnets perfectly defend themselves against demagnetization caused by foreign field sources,
A magnet with a metallic nickel surface has better aesthetics,
They are known for high magnetic induction at the operating surface, which increases their power,
Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for functioning at temperatures approaching 230°C and above...
Considering the possibility of accurate shaping and customization to custom projects, magnetic components can be produced in a broad palette of shapes and sizes, which makes them more universal,
Versatile presence in modern technologies – they are used in mass storage devices, brushless drives, diagnostic systems, and multitasking production systems.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Limitations

Disadvantages of NdFeB magnets:

At strong impacts they can break, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
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 oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
We recommend a housing - magnetic mount, due to difficulties in producing nuts inside the magnet and complex forms.
Potential hazard to health – tiny shards of magnets can be dangerous, if swallowed, which gains importance in the context of child safety. Furthermore, tiny parts of these products are able to disrupt the diagnostic process medical in case of swallowing.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Holding force characteristics

Breakaway strength of the magnet in ideal conditions – what affects it?

The specified lifting capacity represents the maximum value, measured under laboratory conditions, meaning:

on a block made of mild steel, effectively closing the magnetic flux
with a cross-section minimum 10 mm
with an polished touching surface
under conditions of gap-free contact (metal-to-metal)
for force applied at a right angle (pull-off, not shear)
at ambient temperature room level

Practical lifting capacity: influencing factors

It is worth knowing that the application force may be lower influenced by elements below, in order of importance:

Distance – the presence of foreign body (paint, tape, gap) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
Loading method – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet exhibits much less (typically approx. 20-30% of nominal force).
Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
Steel type – mild steel attracts best. Alloy admixtures lower magnetic properties and lifting capacity.
Surface structure – the more even the plate, the better the adhesion and stronger the hold. Unevenness creates an air distance.
Thermal environment – heating the magnet results in weakening of induction. It is worth remembering the thermal limit for a given model.

Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under parallel forces the holding force is lower. In addition, even a slight gap between the magnet and the plate lowers the load capacity.

Warnings

Serious injuries

Risk of injury: The pulling power is so immense that it can result in hematomas, crushing, and even bone fractures. Protective gloves are recommended.

Product not for children

Always keep magnets out of reach of children. Risk of swallowing is significant, and the consequences of magnets connecting inside the body are tragic.

Protect data

Do not bring magnets near a wallet, laptop, or screen. The magnetic field can permanently damage these devices and erase data from cards.

Pacemakers

For implant holders: Powerful magnets affect electronics. Maintain minimum 30 cm distance or request help to work with the magnets.

Heat sensitivity

Standard neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. The loss of strength is permanent.

Caution required

Handle magnets with awareness. Their huge power can shock even experienced users. Be vigilant and do not underestimate their power.

Allergy Warning

Some people suffer from a contact allergy to Ni, which is the standard coating for NdFeB magnets. Frequent touching can result in a rash. We strongly advise use protective gloves.

Threat to navigation

An intense magnetic field interferes with the functioning of magnetometers in phones and GPS navigation. Maintain magnets close to a smartphone to prevent breaking the sensors.

Eye protection

Neodymium magnets are sintered ceramics, meaning they are very brittle. Clashing of two magnets will cause them breaking into small pieces.

Flammability

Fire warning: Rare earth powder is explosive. Do not process magnets without safety gear as this may cause fire.
