Grip strength decreases sharply per each millimeter of distance. Note that even a microscopic distance (e.g., dirt, paint, veneer) strongly diminishes the holding power. Magnets hold most effectively during direct contact; gap weakens the power. Observe how flashily the load capacity fall, when the product does not touch flatly to the metal substrate. When planning the mounting, eliminate additional spacers.

The following data presents the approximate holding capacity necessary to start the downward movement of the magnet down on a vertical metal surface (considering standard friction). The holding force depends on the separation distance between the magnet and the surface.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
MW 8x20 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.39 kg / 0.86 lbs 390.0 g / 3.8 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.26 kg / 0.57 lbs 260.0 g / 2.6 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.13 kg / 0.29 lbs 130.0 g / 1.3 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.65 kg / 1.43 lbs 650.0 g / 6.4 N

When mounting a magnet on a upright plane (e.g., a board), it will maintain just about 1/5 of nominal attraction strength. Gravitational force and a low friction coefficient cause that holders slip faster than they pull off. Designing a vertical fastening? Note that the sliding force is much weaker than the maximum static pull force. On a smooth steel, the magnet will slip down under a significantly smaller cargo. Using a rubber coating can effectively improve the result.

2 mm	50%	0.65 kg / 1.43 lbs 650.0 g / 6.4 N
3 mm	75%	0.98 kg / 2.15 lbs 975.0 g / 9.6 N
5 mm	100%	1.30 kg / 2.87 lbs 1300.0 g / 12.8 N
10 mm	100%	1.30 kg / 2.87 lbs 1300.0 g / 12.8 N
11 mm	100%	1.30 kg / 2.87 lbs 1300.0 g / 12.8 N
12 mm	100%	1.30 kg / 2.87 lbs 1300.0 g / 12.8 N

A too thin steel is incapable of focus the entire magnetic field, which squanders power of the holder. Should you mount a strong magnet to a too thin substrate, the flux will penetrate right through and the holding will be smaller. To utilize the maximum of this magnet's potential, you require a sufficiently solid element of metal. The saturation phenomenon means that on thin elements (e.g., appliance housings), the magnet holds weaker. We recommend selecting the steel cross-section according to the table below.

Table 5: Thermal resistance (stability) - power drop
MW 8x20 / N38

Ordinary NdFeB products lose parameters above the temperature limit. Avoid high temperatures – heat can irreversibly damage this product. With increasing heat, the magnet's force briefly drops. Refrain from using this magnet in hot environments exceeding its safe range. Too high temperature will result in destruction of magnetic properties.

*Engineering note: Heat tolerance depends not only on the material grade, but also on the magnet's shape. Thin magnets (low permeance coefficient) are more susceptible to demagnetization under lower heat stress than taller cylinders. Red status in the table signals a risk of irreversible loss for this particular item.

Two magnets interact from a much further distance than a magnet and sheet setup. The setup of two magnets produces a massive flux and a larger range of performance. Want to build a powerful holder? Apply two magnets instead of one magnet and a steel. Be careful that when connecting a pair of magnets, the pinch force is extreme. The levitation is marginally weaker than the connection force, but still impressive.
*Flux density for N-N configuration reaches ~0 Gs at the midpoint between the magnets (due to field cancellation).
Important: Calculations apply to friction force of two identical magnets (friction coefficient ~0.15 for Ni-Ni layer).

Table 7: Protective zones (implants) - warnings

A strong magnetic field poses a large risk to electronic devices as well as pacemakers. These neodymiums generate a flux that destroys function of sensitive medical devices. Notice: the unseen radiation passes through tissues and housings. Special caution must be exercised by people with cochlear implants and insulin pumps. Also at risk are: mechanical watches, remotes, membranes, and screens. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

Table 8: Impact energy (cracking risk) - warning
MW 8x20 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	13.28 km/h (3.69 m/s)	0.05 J
30 mm	22.94 km/h (6.37 m/s)	0.15 J
50 mm	29.61 km/h (8.23 m/s)	0.26 J
100 mm	41.88 km/h (11.63 m/s)	0.51 J

Magnetic elements are very brittle – a strong collision with metal risks their cracking. Control the attraction moment – a magnet released freely becomes dangerous. Striking energy can cause material chips or dangerous crushing to fingers. Be sure to control the product during mounting so it doesn't hit violently against the metal. A contact at a velocity of dozens of km/h means shattering of the magnet. Wear safety glasses when working with powerful specimens.

Warning: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

In water, the magnet feels stronger thanks to Archimedes' principle. However, remember the water resistance when pulling the rope quickly.

1. Vertical hold

*Note: On a vertical wall, the magnet retains merely a fraction of its nominal pull.

2. Steel saturation

*Thin steel (e.g. computer case) severely weakens the holding force.

3. Thermal stability

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 1.31

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.

This product is an extremely powerful cylinder magnet, composed of advanced NdFeB material, which, at dimensions of Ø8x20 mm, guarantees maximum efficiency. The MW 8x20 / N38 component features a tolerance of ±0.1mm and professional build quality, making it an excellent solution for the most demanding engineers and designers. As a magnetic rod with impressive force (approx. 1.30 kg), this product is in stock from our warehouse in Poland, ensuring lightning-fast order fulfillment. Additionally, its triple-layer Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

This model is ideal for building electric motors, advanced sensors, and efficient magnetic separators, where field concentration on a small surface counts. Thanks to the pull force of 12.75 N with a weight of only 7.54 g, this rod is indispensable in electronics and wherever low weight is crucial.

Since our magnets have a very precise dimensions, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 8.1 mm) using two-component epoxy glues. To ensure long-term durability in automation, 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 strong enough for 90% of applications in automation and machine building, where excessive miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø8x20), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.

This model is characterized by dimensions Ø8x20 mm, which, at a weight of 7.54 g, makes it an element with high magnetic energy density. The key parameter here is the holding force amounting to approximately 1.30 kg (force ~12.75 N), which, with such compact dimensions, proves the high power of the NdFeB material. The product has a [NiCuNi] coating, which protects the surface 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 8 mm. 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.

Strengths and weaknesses of Nd₂Fe₁₄B magnets.

Advantages

In addition to their pulling strength, neodymium magnets provide the following advantages:

They do not lose strength, even during approximately ten years – the reduction in lifting capacity is only ~1% (based on measurements),
Magnets effectively defend themselves against demagnetization caused by ambient magnetic noise,
In other words, due to the metallic layer of gold, the element gains visual value,
They are known for high magnetic induction at the operating surface, which improves attraction properties,
Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
Possibility of exact machining and modifying to precise needs,
Significant place in advanced technology sectors – they are commonly used in mass storage devices, electric motors, diagnostic systems, and technologically advanced constructions.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Limitations

Disadvantages of neodymium magnets:

They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only shields the magnet but also improves its resistance to damage
Neodymium magnets demagnetize 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
Magnets exposed to a humid environment can rust. Therefore during using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
We suggest a housing - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complex forms.
Health risk resulting from small fragments of magnets can be dangerous, in case of ingestion, which becomes key in the context of child health protection. Additionally, small components of these devices are able to complicate diagnosis medical when they are in the body.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Lifting parameters

Maximum magnetic pulling force – what affects it?

Holding force of 1.30 kg is a theoretical maximum value conducted under the following configuration:

on a plate made of mild steel, optimally conducting the magnetic flux
whose thickness is min. 10 mm
characterized by even structure
under conditions of no distance (surface-to-surface)
during pulling in a direction vertical to the mounting surface
at ambient temperature room level

Magnet lifting force in use – key factors

During everyday use, the real power depends on many variables, ranked from most significant:

Space between magnet and steel – every millimeter of distance (caused e.g. by veneer or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
Direction of force – highest force is available only during perpendicular pulling. The resistance to sliding of the magnet along the plate is standardly several times lower (approx. 1/5 of the lifting capacity).
Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the attraction force (the magnet "punches through" it).
Material type – the best choice is pure iron steel. Cast iron may have worse magnetic properties.
Surface quality – the more even the surface, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
Thermal environment – heating the magnet results in weakening of induction. Check the thermal limit for a given model.

Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under shearing force the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the load capacity.

Safe handling of NdFeB magnets

Cards and drives

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

Handling rules

Exercise caution. Rare earth magnets act from a distance and connect with massive power, often quicker than you can react.

Life threat

Patients with a ICD must keep an absolute distance from magnets. The magnetic field can interfere with the functioning of the life-saving device.

Shattering risk

NdFeB magnets are sintered ceramics, meaning they are prone to chipping. Impact of two magnets leads to them cracking into shards.

Heat sensitivity

Regular neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. This process is irreversible.

Keep away from children

Absolutely keep magnets away from children. Risk of swallowing is significant, and the consequences of magnets clamping inside the body are fatal.

Magnetic interference

Navigation devices and smartphones are extremely susceptible to magnetic fields. Close proximity with a strong magnet can ruin the internal compass in your phone.

Skin irritation risks

Medical facts indicate that nickel (standard magnet coating) is a strong allergen. If you have an allergy, refrain from touching magnets with bare hands or select coated magnets.

Mechanical processing

Fire hazard: Neodymium dust is highly flammable. Do not process magnets without safety gear as this may cause fire.

Finger safety

Protect your hands. Two powerful magnets will join immediately with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!
