Magnetic force weakens sharply with every subsequent millimeter of spacing. Note that even a very thin break (e.g., dirt, paint, dust) significantly diminishes the holding power. Neodymiums work optimally at the point of direct contact; gap kills the force. Observe how quickly the parameters fall, when the magnet does not touch flatly to the metal substrate. When calculating the arrangement, discard unnecessary gaps.

The table below presents the theoretical weight limit needed to cause the slippage of the magnet vertically against a upright steel plate (considering typical friction coefficient). The holding force is relative to the distance between the magnet and the metal.

Table 3: Wall mounting (shearing) - vertical pull
MW 5x2 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.21 kg / 0.46 LBS 210.0 g / 2.1 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.14 kg / 0.31 LBS 140.0 g / 1.4 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.07 kg / 0.15 LBS 70.0 g / 0.7 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.35 kg / 0.77 LBS 350.0 g / 3.4 N

When mounting a holder on a upright plane (e.g., a board), it will maintain barely about 20%-30% of its nominal power. Gravitational force and a low friction coefficient cause that products move down faster than they detach. Designing a hanger? Consider that the shear force is significantly lower than the perpendicular breakaway force. On a smooth steel, the magnet will give way down under a much lighter load. Application of an anti-slip coating can effectively improve the result.

12 mm	100%	0.70 kg / 1.54 LBS 700.0 g / 6.9 N

A too thin steel cannot focus the entire magnetic field, which squanders power of the magnet. If you attach a powerful product to a thin surface, the magnetism will penetrate right through and the holding will be smaller. To achieve 100% of this neodymium's power, you need a suitably thick piece of steel. The saturation effect means that on sheet metal structures (e.g., car bodies), the holder holds weaker. We recommend selecting the steel dimension based on the following data.

Standard neodymium magnets lose parameters after exceeding the maximum temperature. Avoid high temperatures – excessive heat can permanently damage this magnet. As the temperature rises, the magnet's capacity momentarily lowers. Refrain from using this magnet close to heaters higher than its safe range. Ignoring the limit will result in destruction of magnetic properties.

*Engineering note: Heat tolerance is determined by both grade, as well as the dimension ratios. Flat magnets (low permeance coefficient) may lose charge permanently under lower heat stress compared to rod 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 magnet and steel combination. The connection of two magnets creates a more powerful interaction and a wider radius of operation. Want to build a strong closure? Utilize two neodymiums instead of a neodymium and a steel. Exercise caution that when bringing together two magnets, the collision energy is huge. The levitation is slightly lower than the attraction, but still impressive.
*Flux density between like poles drops to ~0 Gs in the exact middle of the gap (resulting from vector opposition).
* Calculations apply to friction force of dual matching magnets (friction ~0.15 for Ni-Ni plating).

A strong magnetic field poses a real danger to IT equipment and medical implants. These magnets produce a field that disrupts operation of sensitive medical devices. Remember: the invisible magnetic field acts through matter and glass. Special caution must be taken by people with cochlear implants and insulin pumps. Also at risk are: automatic timepieces, remotes, membranes, and screens. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Neodymium magnets are very brittle – a violent impact against metal risks their cracking. Pay attention to connection velocity – a neodymium left loose speeds with massive force. Impact energy can destroy the magnet or painful pinches to fingers. Be sure to control the product during installation 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. Use safety goggles when working with powerful specimens.

Rust risk: 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. 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 only approx. 20-30% of its max power.

2. Steel saturation

*Thin steel (e.g. computer case) drastically reduces the holding force.

3. Heat tolerance

*For standard magnets, the safety limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.50

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 modern NdFeB material, which, at dimensions of Ø5x2 mm, guarantees maximum efficiency. The MW 5x2 / N38 model features 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. 0.70 kg), this product is available off-the-shelf from our European logistics center, ensuring quick 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 robotics, and broadly understood industry, serving as a positioning or actuating element. Thanks to the pull force of 6.83 N with a weight of only 0.29 g, this cylindrical magnet is indispensable in electronics and wherever low weight is crucial.

Due to the delicate structure of the ceramic sinter, we absolutely advise against force-fitting (so-called press-fit), as this risks immediate cracking of this precision component. To ensure long-term durability in industry, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.

Magnets N38 are strong enough for the majority of applications in modeling and machine building, where extreme miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø5x2), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.

The presented product is a neodymium magnet with precisely defined parameters: diameter 5 mm and height 2 mm. The value of 6.83 N means that the magnet is capable of holding a weight many times exceeding its own mass of 0.29 g. The product has a [NiCuNi] coating, which secures it against oxidation, giving it an aesthetic, silvery shine.

This cylinder is magnetized axially (along the height of 2 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.

Strengths as well as weaknesses of neodymium magnets.

Advantages

Besides their exceptional field intensity, neodymium magnets offer the following advantages:

They do not lose magnetism, even after nearly 10 years – the reduction in power is only ~1% (based on measurements),
Neodymium magnets prove to be extremely resistant to loss of magnetic properties caused by external interference,
By covering with a lustrous coating of silver, the element presents an elegant look,
The surface of neodymium magnets generates a unique magnetic field – this is a distinguishing feature,
Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures reaching 230°C and above...
Considering the potential of accurate molding and customization to unique solutions, magnetic components can be produced in a wide range of shapes and sizes, which makes them more universal,
Key role in electronics industry – they find application in mass storage devices, motor assemblies, medical equipment, as well as technologically advanced constructions.
Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,

Weaknesses

Disadvantages of NdFeB magnets:

To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation as well as corrosion.
Due to limitations in producing threads and complex forms in magnets, we propose using casing - magnetic mechanism.
Potential hazard resulting from small fragments of magnets are risky, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that small components of these magnets are able to complicate diagnosis medical after entering the body.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities

Pull force analysis

Maximum magnetic pulling force – what affects it?

Magnet power was determined for ideal contact conditions, assuming:

using a base made of mild steel, acting as a magnetic yoke
possessing a massiveness of at least 10 mm to avoid saturation
characterized by even structure
without the slightest air gap between the magnet and steel
for force applied at a right angle (pull-off, not shear)
in neutral thermal conditions

Impact of factors on magnetic holding capacity in practice

Effective lifting capacity is affected by specific conditions, mainly (from most important):

Space between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the nominal value.
Metal thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of converting into lifting capacity.
Material type – ideal substrate is pure iron steel. Stainless steels may have worse magnetic properties.
Base smoothness – the smoother and more polished the surface, the larger the contact zone and stronger the hold. Unevenness acts like micro-gaps.
Heat – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).

Lifting capacity testing was carried out on a smooth plate of suitable thickness, under perpendicular forces, however under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.

Warnings

Metal Allergy

Certain individuals have a hypersensitivity to nickel, which is the common plating for NdFeB magnets. Frequent touching might lead to skin redness. We suggest use protective gloves.

Heat warning

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

Hand protection

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

Shattering risk

Despite the nickel coating, the material is delicate and cannot withstand shocks. Do not hit, as the magnet may shatter into sharp, dangerous pieces.

Keep away from computers

Do not bring magnets close to a purse, laptop, or TV. The magnetic field can destroy these devices and erase data from cards.

Pacemakers

Patients with a pacemaker should keep an absolute distance from magnets. The magnetic field can disrupt the operation of the implant.

This is not a toy

Only for adults. Small elements can be swallowed, causing intestinal necrosis. Store out of reach of children and animals.

Flammability

Machining of neodymium magnets poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.

Threat to navigation

Navigation devices and mobile phones are highly sensitive to magnetic fields. Direct contact with a strong magnet can permanently damage the internal compass in your phone.

Powerful field

Use magnets with awareness. Their huge power can surprise even professionals. Be vigilant and do not underestimate their force.
