Magnetic force drops drastically with every mm of gap. Remember that every additional insulation layer (e.g., contamination, varnish, rust) strongly diminishes the holding power. Magnetic products operate most effectively during direct contact; distance kills the power. Observe how rapidly the load capacity plummet, when the product does not adhere flatly to the steel surface. When planning the arrangement, eliminate additional spacers.

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

The table below defines the estimated weight limit required to initiate the sliding of the magnet vertically on a upright steel wall (considering typical friction coefficient). The holding force depends on the distance between the magnet and the surface.

Table 3: Wall mounting (sliding) - behavior on slippery surfaces
MW 2x10 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.02 kg / 0.05 pounds 21.0 g / 0.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.01 kg / 0.03 pounds 14.0 g / 0.1 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.01 kg / 0.02 pounds 7.0 g / 0.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.04 kg / 0.08 pounds 35.0 g / 0.3 N

When hanging a holder on a upright surface (e.g., a fridge), it you can count on only about 1/5 of its nominal power. Gravity and a low friction coefficient cause that holders move down faster than they pop off the substrate. Designing a hanger? Consider that the sliding force is noticeably lower than the maximum static pull force. On a smooth steel, the element will slip down under a significantly smaller load. Using a rubber layer can significantly increase the grip.

Table 4: Steel thickness (substrate influence) - sheet metal selection
MW 2x10 / N38

Steel thickness (mm)	% power	Real pull force (kg/lbs/g/N)
0.5 mm	10%	0.01 kg / 0.02 pounds 7.0 g / 0.1 N
1 mm	25%	0.02 kg / 0.04 pounds 17.5 g / 0.2 N
2 mm	50%	0.04 kg / 0.08 pounds 35.0 g / 0.3 N
3 mm	75%	0.05 kg / 0.12 pounds 52.5 g / 0.5 N
5 mm	100%	0.07 kg / 0.15 pounds 70.0 g / 0.7 N
10 mm	100%	0.07 kg / 0.15 pounds 70.0 g / 0.7 N
11 mm	100%	0.07 kg / 0.15 pounds 70.0 g / 0.7 N
12 mm	100%	0.07 kg / 0.15 pounds 70.0 g / 0.7 N

A too thin steel is incapable of focus the entire magnetic field, which squanders power of the holder. Should you attach a powerful product to a thin surface, the field will penetrate right through and the holding will be smaller. To utilize 100% of this magnet's power, you need a suitably thick element of metal. The material oversaturation means that on delicate walls (e.g., car bodies), the holder shows lower pull force. We recommend selecting the steel thickness according to the table below.

100 °C	-28.8%	0.05 kg / 0.11 pounds 49.8 g / 0.5 N

Standard neodymium magnets lose power above the temperature limit. Protect against heat – excessive heat can irreversibly demagnetize this product. With every degree above norm, the neodymium's force briefly decreases. Refrain from using this magnet close to ovens exceeding its working range. Exceeding the critical threshold will cause permanent loss of magnetism.

*Technical advisory: Thermal stability depends not only on the material grade, but also on the magnet's shape. Flat magnets (low permeance coefficient) risk losing magnetic properties sooner than long magnets. Warning indicator in the table signals a risk of irreversible loss for this particular item.

Two magnets attract each other from a significantly greater distance than a neodymium and metal combination. The connection of two magnets generates a stronger field and a wider radius of operation. Want to build a powerful holder? Apply two magnets instead of one magnet and a steel. Exercise caution that when attracting two neodymiums, the pinch force is extreme. The repulsion force is slightly lower than the connection force, but still impressive.
*The magnetic induction in repulsion mode is approximately ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
Note: Estimates refer to sliding force of dual identical magnets (friction ~0.15 for Ni-Ni coating).

Extremely neodym field is a real danger to IT equipment as well as medical implants. These NdFeB products generate a flux that prevents correct functioning 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, speakers, and screens. Do not bring the product near payment cards, HDD media, or sensitive navigation tools.

Neodymium magnets are prone to chipping – a strong collision with metal risks their cracking. Control the attraction moment – a neodymium left loose speeds with massive force. Striking energy can destroy the magnet or injury to fingers. Hold the magnet firmly during bringing near metal so it doesn't hit with great force against the steel surface. A contact at a velocity of dozens of km/h means shattering of the neodymium. Wear eye protection when working 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. Buoyancy helps in lifting finds.

1. Wall mount (shear)

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

2. Steel saturation

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

3. Heat tolerance

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 1.55

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 incredibly powerful cylindrical magnet, composed of modern NdFeB material, which, with dimensions of Ø2x10 mm, guarantees maximum efficiency. The MW 2x10 / N38 model boasts high dimensional repeatability and professional build quality, making it an excellent solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 0.07 kg), this product is in stock from our European logistics center, ensuring quick order fulfillment. Furthermore, its Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is perfect for building generators, advanced Hall effect sensors, and efficient magnetic separators, where field concentration on a small surface counts. Thanks to the high power of 0.70 N with a weight of only 0.24 g, this rod is indispensable in electronics 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., 2.1 mm) using 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 modeling and machine building, where excessive miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø2x10), 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 Ø2x10 mm, which, at a weight of 0.24 g, makes it an element with high magnetic energy density. The value of 0.70 N means that the magnet is capable of holding a weight many times exceeding its own mass of 0.24 g. The product has a [NiCuNi] coating, which protects the surface against oxidation, 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. 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 rare earth magnets.

Benefits

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

They retain attractive force for around ten years – the drop is just ~1% (based on simulations),
Neodymium magnets prove to be remarkably resistant to loss of magnetic properties caused by magnetic disturbances,
By applying a smooth layer of nickel, the element acquires an aesthetic look,
They show high magnetic induction at the operating surface, making them more effective,
Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for operation at temperatures reaching 230°C and above...
Due to the option of precise molding and customization to unique needs, NdFeB magnets can be manufactured in a variety of geometric configurations, which increases their versatility,
Universal use in modern industrial fields – they find application in magnetic memories, brushless drives, diagnostic systems, and modern systems.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Cons

Disadvantages of neodymium magnets:

They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only shields the magnet but also increases its resistance to damage
Neodymium magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
We recommend cover - magnetic mount, due to difficulties in creating nuts inside the magnet and complex forms.
Potential hazard related to microscopic parts of magnets are risky, if swallowed, which gains importance in the aspect of protecting the youngest. Additionally, small components of these devices are able to be problematic in diagnostics 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

Highest magnetic holding force – what it depends on?

The declared magnet strength represents the peak performance, measured under optimal environment, specifically:

using a sheet made of mild steel, acting as a circuit closing element
with a cross-section minimum 10 mm
with an polished contact surface
with total lack of distance (without paint)
during detachment in a direction perpendicular to the plane
at ambient temperature room level

Impact of factors on magnetic holding capacity in practice

Real force is affected by working environment parameters, including (from most important):

Distance – the presence of foreign body (rust, tape, air) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
Direction of force – maximum parameter is obtained only during perpendicular pulling. The force required to slide of the magnet along the surface is typically several times lower (approx. 1/5 of the lifting capacity).
Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
Metal type – not every steel reacts the same. Alloy additives weaken the interaction with the magnet.
Plate texture – smooth surfaces ensure maximum contact, which increases force. Uneven metal reduce efficiency.
Thermal factor – hot environment reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity was measured with the use of a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, however under parallel forces the lifting capacity is smaller. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.

Safe handling of neodymium magnets

Beware of splinters

Despite metallic appearance, the material is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.

Adults only

Product intended for adults. Tiny parts can be swallowed, leading to serious injuries. Keep away from children and animals.

Mechanical processing

Combustion risk: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this risks ignition.

Respect the power

Before starting, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.

Danger to pacemakers

Health Alert: Neodymium magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.

Electronic devices

Very strong magnetic fields can erase data on credit cards, HDDs, and storage devices. Maintain a gap of min. 10 cm.

Hand protection

Big blocks can smash fingers in a fraction of a second. Never put your hand between two strong magnets.

Phone sensors

Navigation devices and smartphones are extremely sensitive to magnetic fields. Direct contact with a strong magnet can decalibrate the internal compass in your phone.

Do not overheat magnets

Control the heat. Heating the magnet to high heat will permanently weaken its magnetic structure and pulling force.

Nickel coating and allergies

Studies show that the nickel plating (standard magnet coating) is a potent allergen. If you have an allergy, prevent direct skin contact or opt for encased magnets.
