Pulling power decreases drastically with every subsequent millimeter of spacing. Note that even the smallest gap (e.g., contamination, varnish, rust) significantly diminishes the holding power. Magnetic products work optimally in perfect adhesion; gap drastically cuts the power. Observe how rapidly the pull force drop, when the magnet does not touch tightly to the metal substrate. When planning the mounting, eliminate redundant distances.

Table 2: Shear force (vertical surface)
MW 2x10 / N38

The following data calculates the approximate shear load required to initiate the shifting of the magnet vertically on a vertical steel wall (assuming standard friction coefficient). This value depends on the separation distance between the magnet and the surface.

Table 3: Wall mounting (shearing) - vertical pull
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 element on a vertical wall (e.g., a board), it will only hold barely about 1/5 of its nominal power. Gravity as well as a low friction coefficient influence the fact that holders move down faster than they detach. Designing a wall mount? Consider that the shear force is noticeably lower than the perpendicular breakaway force. On a painted metal, the magnet will slide down under a significantly smaller load. Utilizing a rubberized pad can significantly improve the result.

12 mm	100%	0.07 kg / 0.15 pounds 70.0 g / 0.7 N

A too thin steel is unable to absorb the full magnetic flux, which squanders power of the magnet. If you attach a powerful product to a thin surface, the field will penetrate right through and the pull force will drop sharply. To squeeze full efficiency of this neodymium's power, you need a suitably thick element of steel. The saturation phenomenon means that on thin elements (e.g., car bodies), the product works worse. We recommend selecting the steel dimension according to the table below.

Standard neodymium magnets change their properties parameters above the temperature limit. Protect against heat – heat can permanently damage this product. As the temperature rises, the magnet's power briefly drops. Do not use this magnet close to ovens exceeding its working range. Too high temperature will cause irreversible degradation of magnetism.

*Engineering note: Heat tolerance depends not only on the material grade, but also on the magnet's shape. Low-profile magnets (pancake types) risk losing magnetic properties at lower temperatures compared to rod magnets. Red status in the table signals permanent field degradation for this particular item.

Two strong neodymiums interact from a significantly greater distance than a magnet and steel combination. Such a system of magnet-to-magnet generates a stronger field and a wider radius of action. Designing a solid fastener? Use a pair of magnets instead of a neodymium and a steel. Be careful that when attracting two neodymiums, the pinch force is extreme. The levitation is slightly lower than the connection force, but still impressive.
*Flux density for N-N configuration is approximately ~0 Gs at the midpoint between the magnets (resulting from vector opposition).
Note: Results refer to sliding force of a pair of matching magnets (friction coefficient ~0.15 for Ni-Ni plating).

Table 7: Hazards (implants) - warnings
MW 2x10 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	2.0 cm
Hearing aid	10 Gs (1.0 mT)	1.5 cm
Mechanical watch	20 Gs (2.0 mT)	1.5 cm
Mobile device	40 Gs (4.0 mT)	1.0 cm
Remote	50 Gs (5.0 mT)	1.0 cm
Payment card	400 Gs (40.0 mT)	0.5 cm
HDD hard drive	600 Gs (60.0 mT)	0.5 cm

A strong magnetic field poses a large risk to electronics as well as pacemakers. These NdFeB products generate a flux that prevents correct functioning of digital equipment. Be aware: the invisible magnetic field passes through tissues and housings. Special caution must be exercised by people with cochlear implants and insulin pumps. Also at risk are: automatic timepieces, remotes, speakers, and displays. Do not bring the product near payment cards, HDD media, or precise measuring instruments.

Table 8: Collisions (cracking risk) - warning
MW 2x10 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	17.22 km/h (4.78 m/s)	0.00 J
30 mm	29.83 km/h (8.29 m/s)	0.01 J
50 mm	38.51 km/h (10.70 m/s)	0.01 J
100 mm	54.47 km/h (15.13 m/s)	0.03 J

Neodymium magnets are delicate – a strong collision with metal causes immediate chipping. Control the attraction moment – a neodymium left loose speeds with massive force. Kinetic force can trigger coating fragments or injury to skin. Hold the magnet firmly during mounting so it doesn't hit with great force against the metal. A collision at high speed ends with a crack of the magnet. Wear eye protection when handling with powerful specimens.

Water (riverbed)	0.08 kg (+0.01 kg buoyancy gain)	+14.5%

Rust risk: 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. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Vertical hold

*Caution: On a vertical wall, the magnet holds merely ~20% of its max power.

2. Steel thickness impact

*Thin metal sheet (e.g. computer case) drastically limits the holding force.

3. Temperature resistance

*For N38 grade, 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 extremely powerful cylinder magnet, composed of advanced NdFeB material, which, at dimensions of Ø2x10 mm, guarantees optimal power. The MW 2x10 / N38 component boasts high dimensional repeatability and industrial build quality, making it an excellent solution for professional engineers and designers. As a cylindrical magnet with significant force (approx. 0.07 kg), this product is available off-the-shelf from our European logistics center, ensuring quick order fulfillment. Moreover, its Ni-Cu-Ni coating effectively protects it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

This model is created for building electric motors, advanced 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 miniature devices and wherever low weight is crucial.

Due to the brittleness of the NdFeB material, you must not use force-fitting (so-called press-fit), as this risks chipping the coating of this precision component. To ensure long-term durability in automation, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.

Magnets NdFeB grade N38 are suitable 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 (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 secures it against external factors, giving it an aesthetic, silvery shine.

This rod magnet 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 most desirable 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 Nd₂Fe₁₄B magnets.

Pros

In addition to their magnetic capacity, neodymium magnets provide the following advantages:

They do not lose strength, even during around 10 years – the reduction in lifting capacity is only ~1% (based on measurements),
Magnets very well resist against loss of magnetization caused by foreign field sources,
The use of an refined finish of noble metals (nickel, gold, silver) causes the element to present itself better,
Magnetic induction on the working part of the magnet is exceptional,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
Due to the option of flexible forming and adaptation to specialized requirements, neodymium magnets can be created in a variety of geometric configurations, which expands the range of possible applications,
Universal use in advanced technology sectors – they serve a role in magnetic memories, motor assemblies, diagnostic systems, also industrial machines.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Weaknesses

What to avoid - cons of neodymium magnets and ways of using them

To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (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
Magnets exposed to a humid environment can rust. Therefore when using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
Due to limitations in realizing threads and complex shapes in magnets, we propose using casing - magnetic holder.
Potential hazard to health – tiny shards of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. Additionally, tiny parts of these devices can disrupt the diagnostic process medical after entering the body.
High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities

Pull force analysis

Highest magnetic holding force – what affects it?

Breakaway force is the result of a measurement for optimal configuration, taking into account:

with the contact of a sheet made of special test steel, guaranteeing maximum field concentration
possessing a thickness of minimum 10 mm to avoid saturation
characterized by even structure
without any insulating layer between the magnet and steel
for force applied at a right angle (in the magnet axis)
at standard ambient temperature

Practical lifting capacity: influencing factors

During everyday use, the actual holding force is determined by several key aspects, presented from most significant:

Clearance – existence of foreign body (paint, dirt, air) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
Angle of force application – maximum parameter is obtained only during pulling at a 90° angle. The shear force of the magnet along the surface is typically many times lower (approx. 1/5 of the lifting capacity).
Plate thickness – insufficiently thick plate does not close the flux, causing part of the power to be wasted into the air.
Metal type – different alloys attracts identically. Alloy additives weaken the interaction with the magnet.
Surface quality – the more even the surface, the larger the contact zone and higher the lifting capacity. Unevenness acts like micro-gaps.
Thermal factor – hot environment weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity testing was conducted on a smooth plate of suitable thickness, under a perpendicular pulling force, in contrast under shearing force the lifting capacity is smaller. Moreover, even a small distance between the magnet’s surface and the plate decreases the holding force.

Safety rules for work with neodymium magnets

Finger safety

Watch your fingers. Two large magnets will snap together instantly with a force of massive weight, crushing everything in their path. Be careful!

Magnetic interference

An intense magnetic field disrupts the operation of compasses in phones and GPS navigation. Do not bring magnets near a device to avoid breaking the sensors.

Do not underestimate power

Use magnets consciously. Their huge power can shock even experienced users. Be vigilant and respect their force.

Operating temperature

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

Product not for children

Neodymium magnets are not toys. Accidental ingestion of several magnets may result in them connecting inside the digestive tract, which poses a direct threat to life and necessitates immediate surgery.

Fire warning

Dust produced during grinding of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.

Electronic devices

Equipment safety: Strong magnets can ruin data carriers and delicate electronics (pacemakers, hearing aids, mechanical watches).

Sensitization to coating

A percentage of the population suffer from a hypersensitivity to Ni, which is the typical protective layer for NdFeB magnets. Frequent touching might lead to an allergic reaction. It is best to use safety gloves.

Material brittleness

Beware of splinters. Magnets can fracture upon violent connection, ejecting shards into the air. Wear goggles.

Health Danger

For implant holders: Powerful magnets disrupt electronics. Keep minimum 30 cm distance or ask another person to handle the magnets.
