Grip strength weakens drastically with every subsequent millimeter of gap. Remember that even the smallest gap (e.g., dirt, paint, dust) noticeably weakens the grip. Magnetic products work optimally during direct contact; gap weakens the power. Observe how flashily the parameters fall, when the product does not adhere directly to the steel surface. When designing the mounting, eliminate unnecessary gaps.

The following data shows the estimated shear load necessary to cause the slippage of the magnet downwards against a vertical metal surface (considering typical friction coefficient). This parameter depends on the gap size between the magnet and the metal.

Table 3: Vertical assembly (shearing) - vertical pull
MW 10x10 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.95 kg / 2.10 pounds 954.0 g / 9.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.64 kg / 1.40 pounds 636.0 g / 6.2 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.32 kg / 0.70 pounds 318.0 g / 3.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.59 kg / 3.51 pounds 1590.0 g / 15.6 N

When hanging a element on a vertical plane (e.g., a fridge), it will maintain only approx. 1/5 of nominal attraction strength. Gravity as well as a low friction coefficient influence the fact that magnets slip faster than they detach. Planning a hanger? Note that the shear force is much weaker than the maximum static pull force. On a slippery surface, the holder will give way down under a much lighter weight. Using a rubber coating can drastically raise the stability.

3 mm	75%	2.39 kg / 5.26 pounds 2385.0 g / 23.4 N
5 mm	100%	3.18 kg / 7.01 pounds 3180.0 g / 31.2 N
10 mm	100%	3.18 kg / 7.01 pounds 3180.0 g / 31.2 N

12 mm	100%	3.18 kg / 7.01 pounds 3180.0 g / 31.2 N

A thin sheet is incapable of absorb the full magnetic flux, which squanders power of the holder. Should you attach a powerful product to a thin surface, the magnetism will pass right through and the holding will be smaller. To utilize the maximum of this magnet's power, you require a sufficiently solid piece of metal. The saturation phenomenon causes that on delicate walls (e.g., thin profiles), the holder shows lower pull force. We recommend selecting the steel thickness according to the table below.

Classic neodymiums change their properties parameters past the thermal threshold. Protect against heat – heat can irreversibly damage this product. With increasing heat, the magnet's power briefly lowers. Do not use this product near heat sources higher than its safe range. Too high temperature will lead to irreversible degradation of magnetic properties.

*Engineering note: Heat tolerance is determined by both grade, as well as the dimension ratios. Thin magnets (pancake types) risk losing magnetic properties under lower heat stress than long magnets. Red status in the table signals a risk of irreversible loss for this particular item.

Two magnets attract each other from a much further distance than a neodymium and metal setup. The connection of two magnets creates a more powerful interaction and a further horizon of performance. Designing a powerful holder? Utilize two neodymiums instead of a neodymium and a steel. Remember that when connecting a pair of magnets, the impact force is massive. The levitation is marginally weaker than the connection force, but still large.
*Field value between like poles reaches ~0 Gs at the geometric center of the gap (due to field cancellation).
Attention: Figures demonstrate shear force of dual identical magnets (friction ~0.15 for Ni-Ni layer).

Table 7: Protective zones (implants) - precautionary measures
MW 10x10 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	6.5 cm

A strong magnetic field is a real danger to electronics and pacemakers. These neodymiums generate a flux that disrupts operation of sensitive medical devices. Notice: the invisible magnetic field penetrates the body and glass. Increased vigilance must be exercised by people with cochlear implants and insulin pumps. Influence will be felt by: mechanical watches, remotes, membranes, and screens. Do not bring the product near payment cards, HDD media, or sensitive navigation tools.

Table 8: Impact energy (cracking risk) - warning
MW 10x10 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	23.54 km/h (6.54 m/s)	0.13 J
30 mm	40.59 km/h (11.27 m/s)	0.37 J
50 mm	52.40 km/h (14.56 m/s)	0.62 J
100 mm	74.10 km/h (20.58 m/s)	1.25 J

NdFeB products are very brittle – a strong collision with metal risks their cracking. Watch the impact speed – a neodymium left loose becomes dangerous. Striking energy can cause material chips or injury to fingers. Be sure to control the product during bringing near metal so it doesn't hit with great force against the metal. A collision at high speed means shattering of the neodymium. Use safety goggles when playing with large magnets.

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

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

1. Sliding resistance

*Warning: On a vertical wall, the magnet holds merely ~20% of its nominal pull.

2. Steel saturation

*Thin metal sheet (e.g. 0.5mm PC case) significantly reduces the holding force.

3. Temperature resistance

*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) = 0.89

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, composed of modern NdFeB material, which, with dimensions of Ø10x10 mm, guarantees the highest energy density. This specific item boasts an accuracy of ±0.1mm and professional build quality, making it an ideal solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 3.18 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring lightning-fast 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 finds application in modeling, advanced automation, and broadly understood industry, serving as a fastening or actuating element. Thanks to the pull force of 31.15 N with a weight of only 5.89 g, this cylindrical magnet 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., 10.1 mm) using two-component epoxy glues. To ensure long-term durability in automation, anaerobic resins 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 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 (Ø10x10), 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 Ø10x10 mm, which, at a weight of 5.89 g, makes it an element with high magnetic energy density. The value of 31.15 N means that the magnet is capable of holding a weight many times exceeding its own mass of 5.89 g. The product has a [NiCuNi] coating, which secures it against external factors, giving it an aesthetic, silvery shine.

This cylinder is magnetized axially (along the height of 10 mm), which means that the N and S poles are located on the flat, circular surfaces. 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 through the diameter if your project requires it.

Pros as well as cons of rare earth magnets.

Advantages

Besides their remarkable magnetic power, neodymium magnets offer the following advantages:

They do not lose power, even over approximately 10 years – the decrease in lifting capacity is only ~1% (theoretically),
They retain their magnetic properties even under external field action,
A magnet with a shiny nickel surface has better aesthetics,
They are known for high magnetic induction at the operating surface, which increases their power,
Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
Thanks to modularity in constructing and the capacity to adapt to individual projects,
Universal use in high-tech industry – they are used in data components, electric motors, medical devices, and industrial machines.
Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which enables their usage in small systems

Disadvantages

Disadvantages of NdFeB magnets:

At very strong impacts they can crack, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
We suggest casing - magnetic mechanism, due to difficulties in creating threads inside the magnet and complex forms.
Possible danger resulting from small fragments of magnets can be dangerous, if swallowed, which becomes key in the context of child safety. Additionally, small elements of these devices can be problematic in diagnostics medical when they are in the body.
Due to expensive raw materials, their price is higher than average,

Pull force analysis

Maximum lifting capacity of the magnet – what affects it?

Information about lifting capacity is the result of a measurement for ideal contact conditions, including:

using a plate made of mild steel, serving as a magnetic yoke
possessing a massiveness of min. 10 mm to ensure full flux closure
with an ideally smooth contact surface
under conditions of no distance (surface-to-surface)
under perpendicular application of breakaway force (90-degree angle)
at temperature room level

Impact of factors on magnetic holding capacity in practice

Real force is affected by specific conditions, including (from most important):

Space between magnet and steel – every millimeter of distance (caused e.g. by varnish or dirt) diminishes the pulling force, often by half at just 0.5 mm.
Force direction – catalog parameter refers to detachment vertically. When attempting to slide, the magnet holds much less (often approx. 20-30% of maximum force).
Steel thickness – insufficiently thick plate does not accept the full field, causing part of the flux to be escaped to the other side.
Steel type – mild steel attracts best. Higher carbon content lower magnetic permeability and lifting capacity.
Plate texture – smooth surfaces ensure maximum contact, which increases force. Uneven metal weaken the grip.
Thermal conditions – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).

Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under shearing force the lifting capacity is smaller. In addition, even a slight gap between the magnet’s surface and the plate decreases the lifting capacity.

Precautions when working with neodymium magnets

Avoid contact if allergic

Allergy Notice: The nickel-copper-nickel coating contains nickel. If redness appears, cease working with magnets and wear gloves.

Do not overheat magnets

Do not overheat. NdFeB magnets are susceptible to heat. If you require operation above 80°C, look for HT versions (H, SH, UH).

Magnetic media

Data protection: Strong magnets can ruin payment cards and delicate electronics (heart implants, medical aids, mechanical watches).

Choking Hazard

Only for adults. Small elements can be swallowed, leading to severe trauma. Store away from kids and pets.

Pinching danger

Risk of injury: The pulling power is so immense that it can cause blood blisters, pinching, and even bone fractures. Protective gloves are recommended.

Warning for heart patients

People with a ICD should maintain an absolute distance from magnets. The magnetism can disrupt the operation of the life-saving device.

Dust explosion hazard

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

Safe operation

Use magnets with awareness. Their powerful strength can shock even professionals. Be vigilant and do not underestimate their force.

Phone sensors

Note: neodymium magnets generate a field that interferes with sensitive sensors. Keep a safe distance from your mobile, tablet, and navigation systems.

Material brittleness

Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.
