Magnetic force weakens significantly with every subsequent millimeter of spacing. Remember that even the smallest gap (e.g., contamination, paint, veneer) noticeably weakens the grip. Magnetic products operate most effectively in perfect adhesion; gap weakens the force. Notice how quickly the parameters fall, when the magnet does not adhere directly to the metal substrate. When planning the mounting, avoid unnecessary gaps.

This section presents the estimated force sufficient to start the slippage of the magnet vertically against a vertical steel wall (considering standard friction coefficient). This parameter is a function of the distance between the magnet and the surface.

Table 3: Wall mounting (shearing) - vertical pull
MW 30x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	2.61 kg / 5.76 LBS 2613.0 g / 25.6 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.74 kg / 3.84 LBS 1742.0 g / 17.1 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.87 kg / 1.92 LBS 871.0 g / 8.5 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	4.36 kg / 9.60 LBS 4355.0 g / 42.7 N

When placing a element on a upright plane (e.g., a board), it you can count on just about 20%-30% of nominal attraction strength. Gravity and a low friction coefficient mean that products move down faster than they pull off. Want to create a hanger? Consider that the shear force is much weaker than the perpendicular breakaway force. On a painted metal, the magnet will slip down under a noticeably lighter cargo. Application of an anti-slip coating can significantly increase the grip.

A thin metal plate cannot absorb the entire magnetic field, which weakens actual performance of the magnet. If you attach a powerful product to a too thin substrate, the field will penetrate right through and the pull force will drop sharply. To squeeze the maximum of this neodymium's power, you need a suitably thick element of steel. The material oversaturation causes that on sheet metal structures (e.g., car bodies), the magnet holds weaker. We suggest choosing the steel dimension based on the following data.

Ordinary NdFeB products lose power past the thermal threshold. Watch out for overheating – high temperature can permanently destroy this product. As the temperature rises, the magnet's force temporarily decreases. Refrain from using this magnet close to heaters exceeding its working range. Too high temperature will result in irreversible degradation of magnetism.

*Technical advisory: Thermal stability depends not only on the material grade, and the Permeance Coefficient Pc. Flat magnets (low Pc) may lose charge permanently sooner than taller cylinders. The danger warning in the table points to permanent field degradation for this particular item.

Two magnetic products attract each other from a significantly greater distance than a magnet and steel combination. Such a system of two magnets produces a massive flux and a larger range of operation. 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 levitation is marginally weaker than the connection force, but still large.
*The magnetic induction for N-N configuration reaches ~0 Gs at the midpoint of the gap (due to field cancellation).
Note: Calculations apply to friction force of a pair of identical neodymium magnets (friction ~0.15 for Ni-Ni plating).

Table 7: Hazards (implants) - warnings

Powerful magnet radiation is a real danger to electronic devices and medical implants. These neodymiums generate a field that disrupts operation of digital equipment. Notice: the unseen radiation passes through tissues and plastic. Increased vigilance must be taken by people with hearing aids and insulin pumps. The risk also applies to: automatic timepieces, car keys, membranes, and displays. Do not bring the product near payment cards, hard drives, or sensitive navigation tools.

Table 8: Collisions (kinetic energy) - warning
MW 30x5 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	20.77 km/h (5.77 m/s)	0.44 J
30 mm	31.78 km/h (8.83 m/s)	1.03 J
50 mm	40.89 km/h (11.36 m/s)	1.71 J
100 mm	57.81 km/h (16.06 m/s)	3.42 J

NdFeB products are very brittle – a collision with steel can result in shattering. Watch the impact speed – a magnet released freely becomes dangerous. Striking energy can trigger coating fragments or painful pinches to fingers. Hold the magnet firmly during mounting so it doesn't slam with momentum against the steel surface. A contact at a velocity of dozens of km/h ends with a crack of the neodymium. Wear safety glasses when handling with large magnets.

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

The magnetic field penetrates through water without any losses. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Shear force

*Note: On a vertical surface, the magnet holds merely ~20% of its perpendicular strength.

2. Steel saturation

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

3. Thermal stability

*For standard magnets, 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) = 0.25

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 incredibly powerful cylindrical magnet, produced from durable NdFeB material, which, at dimensions of Ø30x5 mm, guarantees the highest energy density. This specific item boasts a tolerance of ±0.1mm and industrial build quality, making it a perfect solution for the most demanding engineers and designers. As a magnetic rod with significant force (approx. 8.71 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring rapid order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is ideal for building generators, advanced Hall effect sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the high power of 85.42 N with a weight of only 26.51 g, this cylindrical magnet is indispensable in miniature devices and wherever every gram matters.

Since our magnets have a very precise dimensions, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 30.1 mm) using two-component epoxy glues. To ensure stability in automation, 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 strong enough 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 (Ø30x5), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.

The presented product is a neodymium magnet with precisely defined parameters: diameter 30 mm and height 5 mm. The value of 85.42 N means that the magnet is capable of holding a weight many times exceeding its own mass of 26.51 g. 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 30 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.

Pros as well as cons of neodymium magnets.

Strengths

Apart from their strong power, neodymium magnets have these key benefits:

They virtually do not lose power, because even after 10 years the performance loss is only ~1% (according to literature),
Magnets effectively resist against demagnetization caused by ambient magnetic noise,
The use of an aesthetic layer of noble metals (nickel, gold, silver) causes the element to have aesthetics,
Magnets exhibit maximum magnetic induction on the outer layer,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
Possibility of accurate shaping as well as adapting to individual needs,
Key role in high-tech industry – they are commonly used in HDD drives, electromotive mechanisms, medical devices, and other advanced devices.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which allows their use in compact constructions

Disadvantages

Characteristics of disadvantages of neodymium magnets and ways of using them

To avoid cracks under impact, we suggest using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
We suggest a housing - magnetic holder, due to difficulties in producing nuts inside the magnet and complex forms.
Health risk related to microscopic parts of magnets can be dangerous, if swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, small components of these devices can be problematic in diagnostics medical in case of swallowing.
Due to complex production process, their price is higher than average,

Lifting parameters

Maximum lifting capacity of the magnet – what contributes to it?

The declared magnet strength concerns the maximum value, measured under optimal environment, specifically:

using a sheet made of mild steel, functioning as a circuit closing element
possessing a thickness of at least 10 mm to avoid saturation
characterized by even structure
under conditions of no distance (surface-to-surface)
during pulling in a direction perpendicular to the mounting surface
at ambient temperature approx. 20 degrees Celsius

Lifting capacity in real conditions – factors

In practice, the real power is determined by several key aspects, ranked from crucial:

Clearance – existence of any layer (paint, tape, air) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
Force direction – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
Material type – the best choice is high-permeability steel. Cast iron may attract less.
Surface condition – smooth surfaces ensure maximum contact, which improves field saturation. Uneven metal reduce efficiency.
Thermal factor – hot environment weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.

Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the load capacity is reduced by as much as 75%. Moreover, even a slight gap between the magnet’s surface and the plate lowers the load capacity.

Safe handling of neodymium magnets

Protect data

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

Warning for allergy sufferers

Allergy Notice: The Ni-Cu-Ni coating contains nickel. If skin irritation appears, cease working with magnets and use protective gear.

Dust is flammable

Dust generated during machining of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.

Phone sensors

Remember: neodymium magnets generate a field that disrupts precision electronics. Keep a safe distance from your mobile, tablet, and GPS.

Risk of cracking

Beware of splinters. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. Wear goggles.

Medical implants

Life threat: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have medical devices.

Do not underestimate power

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

Bone fractures

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

Danger to the youngest

Neodymium magnets are not suitable for play. Accidental ingestion of a few magnets can lead to them pinching intestinal walls, which constitutes a severe health hazard and requires urgent medical intervention.

Heat sensitivity

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